Activity Concentrations Of Natural Radionuclides Research Articles

The dependence of natural radioactivity levels and its radiological hazards on the texture of agricultural soil in Upper Egypt

To control outdoor exposure to natural radiation, assessment of activity concentrations of the radionuclides in soils is substantial. In this paper, the activity concentration of natural radionuclides (226Ra, 232Th, 40K) was estimated for 174 agriculture soil samples using a sodium iodide detector (NaI) of (3” × 3”). Soil samples were collected from seven regions (56 locations) in EL-Minya governorate, Upper Egypt. The variability of natural activity concentration with soil’s textures was checked. The texture types of soil samples were silt clay loam, clay loam, sandy clay loam, and sandy silt loam. The obtained results indicate that the mean values of specific activity ranged from 11.3 ± 0.5 (sandy silt loam) to 21 ± 1(silt clay loam), 6.8 ± 0.3 (sandy silt loam) to 13.7 ± 0.7 (sandy clay loam), and 112 ± 5 (sandy silt loam) to 272 ± 13.6 (sandy clay loam) Bq kg−1 for 226Ra, 232Th, and 40 K, respectively. The obtained results were compared with the global average and tolerable limits as recommended in UNSCEAR 2008. On the other side, the radiological hazard resulting from the total natural radioactivity in the studied soil samples was estimated by different approaches. The obtained values were within the recommended safety limit and do not pose significant radiation hazards.

Radioactive investigation of Malaysia’s building materials containing NORM and potential radiological risks analysis using RESRAD-BUILD computer code

ABSTRACTThe activity concentrations of natural radionuclides from 80 samples of Malaysia’s building materials sourced from either manufacturers or local suppliers were studied using high-purity germanium (HPGe) detector. The radiological hazards associated with building materials under study were evaluated by calculating radium equivalent activity (Raeq). The calculated values of Raeq range from 29.7 ± 0.9 to 564.8 ± 13.6 Bq kg−1 with an overall average value of 198.1 ± 98.5 Bq kg−1. The calculated activity concentrations of 226Ra, 232Th and 40 K were further subjected to RESRAD-BUILD computer code with a view to determine long-term indoor external and internal doses received by a dweller from zero to 70 years. A significant variation in the indoor doses from zero to 30 years was observed while a relatively constant behaviour was observed from 30 to 70 years. The assessment of the indoor doses also showed that the indoor doses from walls are significantly high compared with indoor doses from the room floor. The calculated Raeq and long-term projection of indoor doses received by the dweller was below the recommended maximum values of 370 Bq kg−1 and 1000 µSv y−1, respectively. Therefore, the potential radiological hazards associated with building materials under study are negligible.

Assessment of excess lifetime cancer risk of sand samples used as building materials in Tiruvannamalai district, Tamil Nadu, India by gamma ray spectrometry

The radionuclide activity data of riverbed sand samples collected from 15 different locations along the banks of Thenpennai River flows within Tiruvannamalai district of Tamilnadu, India were implemented to evaluate the radio- logical safety of the geographical area. The activity concentrations of natural radionuclides were determined using gamma ray spectrometry. The sand samples believed to be undisturbed, were collected from a number of locations at a depth of 5–20 cm from the surface. In this region, the mean activity concentrations for the radionuclides utilized to conduct the calculations were; 226Ra at 5.24 Bq/Kg, 232Th at 112.19 Bq/Kg, and 40K at 360.96 Bq/Kg. The radiation hazard for residents was assessed by radium equivalent activity (Raeq), indoor air absorbed dose rate (D), annual effective dose (AEDE) and excess lifetime cancer risk (ELCR). The results reported were all below the recommended maximum values. Therefore, the radiological hazards attributed to building materials under study are negligible. The use of sand in construction of dwellings is considered to be safe for inhabitants.

Natural radioactivity and radiological hazard of red-clay brick produced in Shangluo, China

The radiological hazard of building materials originating from clay, rock and other mineral wastes has attracted more attention because they contain natural radionuclides (226Ra, 232Th, and 40K). The activity concentration of radionuclides in red-clay brick samples obtained from three different brickyards in Shangluo, China waHs measured. Various indexes, including radium equivalent activities, Raeq, external hazard index, Hex, internal hazard index, Hin, indoor air absorbed dose rate, D, and annual effective dose, AED, of the aforementioned radionuclides in the bricks were used to assess the radiation hazard for people. The average activity concentrations of 226Ra, 232Th, and 40K were respectively 34.5 ? 1.9, 62.5 ? 2.1, and 713.7 ? 19.8 Bqkg?1 for the studied red-clay bricks. The Raeq values of the red-clay brick samples varied from 167.0 to 184.7 Bqkg?1, which are lower than the limit of 370 Bqkg?1. Moreover, the activity concentrations of natural radionuclides in unfired brick, clay and coal were also determined and the results were compared with that in the red-clay brick samples. This study shows that the red-clay bricks produced in Shangluo, China can be used safely in construction industries.

Environmental radon, its exhalation rates and activity concentration of 226Ra, 232Th, and 40kK in Northern India

Human beings are constantly exposed to radioactivity in the environment. As they are major sources of harmful radiation, radionuclides found in the atmosphere might result in a substantial potential risk to living beings. On the Earth's surface, the radioactive elements uranium and radium are naturally present, contributing to radon and thoron gases in the indoor as well as outdoor climate, soil and water. Radon is one of the most important toxins that, after cigarette smoking, is the second most common cause of generating lung cancer. Due to these health-related concerns, a lot of work has been undertaken by numerous research organizations to determine their levels at different locations throughout the world. This paper is an attempt to comprehensively report with different techniques all those studies being carried out in this part of India so that a current assessment of the indoor radon levels should be available for further work in this field. Six northern Indian states, viz. Punjab, Haryana, Himachal Pradesh, Rajasthan , Uttar Pradesh and Uttarakhand are considered for this examination. This study also provides data on exhalation rates and activity concentration of natural radionuclides (226Ra, 232Th, and 40K) present in these states.

Radiometric and environmental impacts of mill tailings at experimental plant processing unit, Allouga, Egypt

Uranium mining and ore processing are known to be harmful to the environment and human health if the waste generated is not managed properly. The aim of the present study is to determine the radiological indices in the mill tailings and review the possible attempts to utilize and minimize its hazardous effect. The activity concentrations of natural radionuclides, 238U, 232Th, 226Ra, and 40K have been measured by gamma spectrometry using HP-Ge detector. The average activity concentrations of 238U, 232Th, 226Ra, and 40K in the tailings wastes were 2071.8, 59.92, 6921.262, and 445. 57 Bq/kg respectively which are higher than the international average limit. The ranges of hazard indices such as Radium equivalent activity (Raeq), external hazard index (Hex), internal hazard index (Hin), γ-radiation hazard index Iγ, Dose rate (nGy/h) and annual effective dose equivalent (AED), were estimated. Uraniumm isotopic ratios in the ore –material and mill tailing samples indicate migration out of radionuclides to the surrounding environment causing contamination and many dangerous diseases. Fairly, all investigated tailing waste samples do not satisfy the universal standards, the studied wastes relatively still have high uranium contents and need reprocessing.

P.472 Cognition and language in Parkinson´s disease

In topsoils, the activity concentrations of natural radionuclides (hereafter NRs) increase due to the addition of NRs from fertilizers, irrigation water, and air dust pollution. On the other hand, various physical-chemical and environmental processes such as radioactive decay, volatilization, leaching, erosion, and plant uptake were responsible for the decrease of the activity concentrations of NRs in the topsoils. In this study, behaviours of 40K, 210Pb, 226Ra, 238U, and 232Th in topsoils were modelled by the CEMC soil model and the HYDRUS-1D model. An exponential equation was proposed for estimating the accumulation rates of these radionuclides in the topsoils. Long-term accumulation of radionuclides was assessed for water spinach (Ipomoea Aquatica Forssk.) soil (hereafter VES) and rice (Oryza sativa L.) soil (hereafter RIS). We found that the current agricultural practices caused the increase of 40K activity concentration in the water spinach soil, and 40K, 210Pb, 226Ra, and 232Th activity concentrations in the rice soil. The accumulation rates of radionuclides were in the order 238U < 232Th < 226Ra < 210Pb < 40K. 25 years of cultivation with water spinach can increase/decrease + (165 ± 6) Bq of 40K, – (8.2 ± 0.7) Bq of 210Pb, – (4.3 ± 0.2) Bq of 226Ra, – (7 0.3 ± 0.3) Bq of 238U, and – (1.8 ± 0.1) Bq of 232Th in 1 kg soil. For rice cultivation, these values are + (1004 ± 39), + (3.3 ± 0.2), + (3.0 ± 0.2), – (5.1 ± 0.3), (2.2 ± 0.1) Bq kg−1 for 40K, 210Pb, 226Ra, 238U, and 232Th, respectively.

Assessment of radioactivity in commercially available honey in Italy

Activity concentration of natural radionuclides and 137Cs were estimated in 28 honeys purchased from large supermarket chains in Italy. Uranium, polonium and thorium were measured by alpha spectrometry, 40 K and 137Cs by gamma spectrometry and 226Ra by liquid scintillation. The concentrations were 50.6 ± 46.3, 0.023 ± 0.010, 0.019 ± 0.017, 0.27 ± 0.40 Bqkg−1 for 40 K, 238U, 234U and 210Po respectively. 235U, 228Th, 232Th were consistently <0.007 Bqkg−1 and 226Ra <0.200 Bqkg−1. 137Cs was <2.1 Bqkg−1 in 93% of the samples. The activity of radiocesium was found to be above the minimum detectable level in only two samples and did not exceed the highest permitted level for food contributing to the overall radioactivity only slightly. The effective doses attributable to 210Po accounts for 0.0026–5.31% of global human exposure to natural radiation. The honeys that were tested were found to be of good quality with regard to the parameters under study, confirming the general image of honey as a genuine healthy product.

NATURAL RADIONUCLIDES IN SOIL AND ROOT VEGETABLES IN MALAYSIA: TRANSFER FACTORS AND DOSE ESTIMATES.

Tapioca and sweet potato are the fourth and fifth most consumed crops in Malaysia. The activity concentrations of natural radionuclides in these vegetables were assessed from two regions in Malaysia (Kedah and Penang) along with soil samples using gamma ray spectroscopy. The transfer factors of 226Ra, 232Th and 40K from soil to vegetables were calculated, and a dose assessment was performed. The activity concentrations of 226Ra, 232Th and 40K in soil samples did not show a significant variation with the regions investigated, and the average values obtained, in Bq/kg, (±SD) were as follows: 80±41, 56±12, 516±119, respectively. The respective average activity concentrations in vegetables were as follows, in Bq/kg: (±SD) 2.0±0.5, 6±2, 153±49. The corresponding transfer factors were calculated to be 0.03, 0.11 and 0.31 for 226Ra, 232Th and 40K, respectively. The average annual effective doses due to the exposure from soil and ingestion of vegetables were found to lie within the worldwide ranges.

NATURAL RADIATION EXPOSURE TO THE PUBLIC IN MINING AND ORE BEARING REGIONS OF CAMEROON.

Within the framework of a joint research project on natural radiation exposure and its health effects in Cameroon from 2014 to 2017, the Institute of Geological and Mining Research and the Hirosaki University worked together to carry out natural radiation survey in mining and ore bearing regions of Cameroon. Air kerma rates were measured using car-borne survey method. In-situ gamma spectrometry was used to determine activity concentrations of 238U, 232Th and 40K in soil. A total of 450 RADUET detectors and 350 thoron progeny monitors were deployed in dwellings of the study areas for 2-3 months, collected and analysed. Although natural radioactivity level seems to be normal in most of the surveyed areas, there are many points where activity concentrations of natural radionuclides are largely above the world average values. Indoor radon, thoron and thoron progeny results show the importance to put in place the national radon plan in Cameroon. It was also pointed out that thoron cannot be neglected when assessing inhalation dose.

NATURAL RADIONUCLIDES IN AGRICULTURAL PLANTS FROM NORTHERN THAILAND.

Thailand is predominantly an agricultural country. The Northern Region occupies the second largest cultivated land area in the country. To establish baseline data for future environmental monitoring, seventy-nine plant samples including vegetables, fruits and tobaccos and their relevant soils were collected from the major plantation zones of Northern Thailand. Activity concentrations of natural radionuclides in the samples were determined using gamma-ray spectrometry technique. The median activity concentrations of 226Ra and 228Ra in the soil samples were higher than worldwide value, while as those of 40K were comparable with worldwide value. There was a large variation and non-uniform distribution in the soil samples. The activity concentrations of 226Ra, 228Ra and 40K in the plant samples varied widely within plants and between species and were very low compared to their relevant soils. A decreasing trend of their activity concentration has been observed in the order leaf > stem > rhizome/root (as found in galangal); and leaf > stalk/stem (as found in lemongrass).

Assessment of natural radionuclide enrichment and radiation hazard from building materials in Kannur District, Kerala

The activity concentrations of natural radionuclides from the 238U and 232Th series and singly occurring radionuclide 40K have been assessed in most commonly used building materials in Kannur district, Kerala, using well established gamma ray spectrometry employing 5 cm × 5 cm scintillation NaI (Tl) detector. The results of the present work include activities of radionuclides viz. 40K, 226Ra and 232Th and associated radiological parameters. The important and expected significant parameters estimated from the activities were radium equivalent activity (Raeq), hazard indexes and dose parameters. The study indicates that all the estimated parameters are within the recommended safety limit except for average value of excess life time cancer risk, which is slightly higher than the world average value (0.29 × 10−3). The present investigation suggests that, the contribution to the radiation dose due to the use of these materials for the building construction is insignificant and do not contribute substantial radiation hazards to the occupants. The results of these systematic investigations are presented and discussed in the manuscript.

Characterization of radiation dose and soil-to-plant transfer factor of natural radionuclides in some cities from south-western Nigeria and its effect on man

Abstract Activity concentrations of natural radionuclides, artificial radiocaesium, and soil-to-plant transfer factor have been evaluated in soils and plant (Amaranthus hybridus) samples from eighteen locations in south-western Nigeria with the aid of a co-axial type, High Purity Germanium (HPGe) detector. The mean specific activities of 40K, 226Ra, 232Th and 137Cs in the soil samples were 393.73 Bq kg−1, 52.91 Bq kg−1, 76.79 Bq kg−1 and 1.44 Bq kg−1, respectively, while the mean specific activities of 40K, 226Ra, and 232Th in plant samples were 3,271.66 Bq kg−1, 25.88 Bq kg−1, and 19.90 Bq kg−1, respectively. 137Cs was found to be below detection limit in the plant samples from all locations of the study area. The radium equivalent concentration, the external and internal hazard indices were estimated, and ranged from 28.47 to 701.53 Bq kg−1, 0.08 to 1.89, and 0.10 to 2.33, with mean values of 191.34 Bq kg−1, 0.52, and 0.66, respectively. The mean soil-to-plant transfer factors for 40K, 226Ra and 232Th were 26.58, 0.62, and 0.39, respectively. The mean absorbed dose and the mean annual outdoor effective dose equivalent in soil samples were 86.44 nGy h−1 and 0.1060 mSv y−1, respectively. The mean annual effective dose equivalent for the study area is higher than the world average (0.07 mSv y−1) and international recommended standards of 0.1 mSv y−1 recommended by World Health Organization (WHO). The excess lifetime cancer risk (ECLR) ranged from 7.35 × 10−5 to 1.36 × 10−3, with a mean of 3.71 × 10−4. This value is higher than the world average of 2.9 × 10−4 reported by United Nations Scientific Committee on the Effects of Atomic Radiation UNSCEAR. The ELCR is a function of environmental geology and 40K has very high soil-to-plant transfer factor compared to other radionuclides in the samples. Regression analysis showed that there was no linearity in the relationship between activity concentration of radionuclides in soil and in plant. This shows that soil-to-plant transfer factor is not a function of soil radioactivity.

Assessment of natural radionuclides and related occupational risk in agricultural soil, southeastern Nile Delta, Egypt

This study aims to determine the activity concentrations of natural radionuclides (226Ra, 232Th, and 40K) in the agricultural soil of southeastern Nile Delta, Egypt, in order to assess their influence on the occupational radiation health hazard indices. It was found that the mean activity concentrations of 226Ra, 232Th, and 40K were 35.53, 23.59, and 266.41 Bq kg−1, respectively. The effect of the industrial activities in the study area on the activity concentrations of radionuclides is slight for 226Ra while negligible for 232Th and 40K. Soil characteristics especially the fine particles play the major role in the distribution of 40K, while the distribution of 232Th is less influenced by the soil characteristics. On the other hand, the distribution of 226Ra shows no obvious association with these characteristics. The calculated radium equivalent activity index (Raeq) and external hazard index (Hex) fall within the save rang. However, those of absorbed dose rate (Dex) and annual effective dose (AEDex) exceed the world average values in about 16.7% and 61.1%, respectively. The calculated values of the excess lifetime cancer risk (ELCR) are higher than those of the world average. This implies the high probability of developing cancer over the lifetime of the farm workers. In this study, we recommend performing periodical inspection for the industrial activities and their wastes in the study area and monitoring the level of activity concentrations of different radionuclides in the studied soil as well as the cultivated crops.

Natural Radionuclides Content in Granites from Operational Quarry Sites

Natural radionuclides content in granite from eight functional quarries in Osun State, Southwestern Nigeria was assessed. Eighty granite samples comprise &frac34 inches. &frac12 inch and stone-dust were collected from Wolid, Slava, Ayofe, Espro, Ife/Modakeke, Krystal Vountein, Clario and Omidiran quarries in the State. Measurement was done using a high purity germanium (HPGe) detector. The statistical analysis was carried out using Statistical Package for Social Sciences (SPSS) software to determine if granite size has an impact on the activity concentrations. The results revealed that the mean activity concentrations of 238U (12.64 ± 1.89 Bq·kg -1) and 232Th (16.93 ± 2.46 Bq·kg -1) were highest in &frac34 inch granite and lowest in stone-dust (5.01 ± 0.77 and 8.97 ± 1.37 Bq·kg -1 respectively), whereas 40K is highest in the &frac34 inches (266.19 ± 35.53 Bq·kg -1) and lowest in &frac12 inches (151.85 ± 25.09 Bq·kg -1) granite. Espro has the highest (23.75 ± 3.74 Bq·kg -1) while Wolid has the lowest (4.11 ± 0.73 Bq·kg -1) 238U activity concentration and Slava has lowest for 232Th (8.21 ± 1.12 Bq·kg -1) and 40K (109.54 ± 11.06 Bq·kg -1). The radiological hazard parameters such as absorbed dose, annual effective dose radium equivalent, gamma index, external index, and internal index, were calculated to assess the radiation hazards associated with granite samples. The results obtained are lower than the recommended limits. The results were compared with the published data of other countries. Although, all the calculated radiation hazard indices were lower than the permissible limits. Therefore, people working in the quarries, granite end-users and the general public are safe from radiological health risks from the quarries, since there is no significant health hazard. The research will give reliable information on activity concentrations of natural radionuclides in granite rocks, contribute to a better understanding of radioactivity distribution in granite, and develop standards.

Radionuclides and heavy metals in soil, vegetables and medicinal plants in suburban areas of the cities of Belgrade and Pancevo, Serbia

The content of radionuclides (40K, 238U, 226Ra, 232Th, and 137Cs) and heavy metals (As, Cd, Cu, and Pb) was determined in samples of soil, vegetables and medicinal plants collected in the period 2007-2017, from two suburban areas of Belgrade ? the municipalities of Palilula and Surcin, and Pancevo ? the 'Dr Josif Pancic' Institute for the Study of Medicinal Herbs. During the research period, activity concentration of 137Cs in soil decreased from 16 Bqkg?1 to 3.9 Bqkg?1 (Palilula, Belgrade) and from 18 Bqkg?1 to 12 Bqkg?1 (Surcin, Belgrade). Mean activity concentrations of natural radionuclides in the soil were higher than the global aver- age. Trend for heavy metal levels, according to the average concentrations found in the soil, were as follows: Cu &gt;Pb &gt;As &gt;Cd for Palilula, Pb &gt;Cu &gt;As &gt;Cd for Surcin and Dr Josif Pancic' Institute, Pancevo. The obtained results indicate that the industrial pollution has no impact on food production in the study area and that the main anthropogenic source of radionuclides and heavy metals in soil are mineral phosphorous fertilizers, often used in agricultural fields.

Naturally occurring radioactive materials in metallic mine wastes from northeaster Guanajuato Mexico: a scoping study

Accumulation of mine wastes with high concentrations of potentially toxic elements has been occurring in different mining regions of Mexico. Few data are available on the activity concentration of natural radionuclides in metallic mine wastes. Radioactive data is necessary to assess the impact of mine wastes from a radiological point of view. In this work, levels of natural radioactivity in a metallic mine wastes area from Xichu in northeaster Guanajuato Mexico, have been determined. This region is characterised by the mining of 'skarn' ores containing silver, and copper, among other elements. The radiometric characterisation of mine wastes has been performed by gamma-ray and alpha-particle spectrometry. The obtained results of the activity concentration cover the ranges of 4-11, 4-38 and 548-1,739 Bq kg‒1 for U and Th natural series and 40K respectively. These results are comparable with the averages values found in unperturbed soils worldwide, and the radiological impact is negligible.

Measurement of Radioactivity And Assessment of Radiological Hazard of Tea Samples Collected From Local Market In Bangladesh

The activity concentrations of natural radionuclides and radiological hazard indices in eleven tea samples collected from local market in Bangladesh have been analyzed by using High Purity Germanium (HPGe) Detector. The average activity concentrations of 226Ra, 232Th and 40K in tea samples have been found to be 21.21±14.04, 32.43±7.48 and 93.47 ± 43.94 Bqkg-1 respectively. The calculated absorbed dose rates due to these radioactive nuclides in tea samples have been found to vary from 26.24 nGyh-1 to 37.95 nGyh-1 and average value was 33.28 nGyh-1. The estimated outdoor annual effective dose rates varied from 38.64 µSvy-1 to 55.89 µSvy-1 with the mean value of 49.02 µSvy-1 which is less than the world average value of 1000 µSvy-1. The values of radium equivalent activity in all samples are less than the permissible maximum value of the radium equivalent activity which is 370 Bqkg-1 according to UNSCEAR 2000 report. The values of external and internal hazard indices for different samples varied from 0.16 to 0.23 with the average value of 0.20 and from 0.21 to 0.29 with an average of 0.26. The value of this index must be less than unity in order to keep the radiation hazard insignificant. It was also found that there is no artificial radionuclide (for example 137Cs) in any of the samples. The data generated in this study will provide baseline radiometric values for natural and artificial radioactivity in tea samples in Bangladesh.&#x0D; Journal of Bangladesh Academy of Sciences, Vol. 42, No. 2, 171-176, 2018

ASSESSMENT OF TERRESTRIAL RADIATION BY DIRECT MEASUREMENT OF AMBIENT DOSE EQUIVALENT RATE OF BACKGROUND RADIATION.

Estimation of terrestrial external radiation is essential for assessment of public exposure to natural radiation. During national survey of natural radionuclide in soil in Iran, 979 soil samples were collected from different locations, in the same time ambient dose equivalent rate was measured by a scintillator detector. In this work, terrestrial radiation was estimated by direct measurement of ambient dose equivalent rate of background radiation. The response of dose measuring instrument to cosmic radiation at ground level was measured and other components were discussed and estimated. For verification, terrestrial radiation derived from this method was compared with those calculated from activity concentration of natural radionuclides in soil. The averages of ambient dose equivalent rate derived from activity concentration of by natural radionuclide in soil and from direct measurement are 55.07 and 62.57 nSv/h, respectively. The source of statistical and systematic uncertainties are introduced and discussed.
