Prediction Model for Defects in Lead and Lead-free Aprons.

Personal radiation protective equipment (PRPE) is prone to defects in the attenuating layers, resulting in inadequate protection. Hence, quality control (QC) of PRPE is needed to assess its integrity. Unfortunately, QC of PRPE is laborious and time consuming. This study aimed to predict the QC outcome of PRPE without x-ray imaging based on readily available predictors. PRPE QC data of a general hospital from 2018 to 2023 was used for both prediction models based on logistic regression and random forests (RF). The data were divided into a training set containing all data from 2018 to 2022 and a holdout set containing the data from 2023. The predictors were brand, age, size, type, visual defects, and department. The prediction performances were compared using confusion matrices and visualized with receiver operating characteristic (ROC) curves. Prediction accuracies of at least 80% were achieved. Further model tuning especially improved the RF model to a precision up to 97% with a sensitivity of 80% and specificity of 86%. All predictors, except visual defects, significantly impacted the probability of passing. The predictor brand had the largest contribution to the predictive performance. The difference in pass probability between the best-performing and the worst-performing brand was 35.1%. The results highlight the potential of predicting PRPE QC outcome without x rays. The proposed prediction approach is a significant contribution to an effective QC strategy by reducing time consuming x-ray QC tests and focusing on garments with higher probability of being defective. Further research is recommended.

Factors influencing radiologic technologists’ commitment to radiation protective equipment utilization in fluoroscopy units: an analysis using the health belief model scale

Objective: This study aimed to assess the perceptions of radiologic technologists towards the use of radiation protective equipment (RPE) in fluoroscopy units and to identify the Health Belief Model constructs, “perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy”, that predict RPE utilization among radiologic technologists. Methods: A cross-sectional observational study was conducted among 228 radiologic technologists in Saudi Arabia. Data were collected using a self-administered questionnaire that included socio-demographic characteristics, frequency of RPE utilization, and the Health Belief Model. Logistic regression was used to identify the predictors of RPE utilization. Results: The findings indicate that 63% of radiologic technologists reported always being committed to using RPE, while 37% reported not fully committed. Perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy showed significant associations with RPE utilization between the two groups of radiologic technologists: those who always use RPE and those who are not fully committed (p < 0.05). Logistic regression showed that perceived benefits were a significant predictor of RPE utilization (AOR = 0.20, 95% CI: 0.60–0.67, p = 0.009), and type of hospital was also a significant predictor (AOR=0.09, 95% CI: 0.1–0.97, p = 0.047). Conclusion: The study highlights the need for interventions to improve the consistent use of RPE among radiologic technologists in fluoroscopy units. Emphasizing the importance of RPE usage, addressing barriers, and providing adequate cues to action can help enhance radiologic technologists’ commitment to using RPE and reduce radiation exposure risks. Tailoring interventions to the specific hospital setting and considering the perceived benefits of using RPE are crucial for promoting a culture of safety and accountability in different healthcare settings.

Current status of occupational radiation exposure and protection among medical interns and residents

Background: While individuals exposed to radiation in hospitals are typically registered as radiation workers, with regulated exposure levels, many interns and residents who are not registered as radiation workers are occupationally exposed to radiation. This study aimed to assess the current status and awareness of radiation exposure and related protective practices among interns and residents.Methods: An online survey was conducted nationwide from June 3 to June 16, 2023, engaging 262 interns and 799 residents. Descriptive analyses were conducted to summarize the status of occupational radiation exposure and radiation protection practices.Results: Approximately 6% of interns and 18% of residents reported receiving personal dosimeters, and 6% and 20%, respectively, were registered as radiation workers. In contrast, compliance with personal radiation protection equipment, such as lead aprons and thyroid shields, exceeded 85% during tasks involving radiation exposure. On average, interns spent 7 months (standard deviation [SD], 2.1) and residents 8.1 months (SD, 4.8) in main departments with potential radiation exposure. While overall safety performance showed improvement, the provision of personal dosimeters and radiation worker registration remained low (14.7%, 16.6%).Conclusion: Despite improvements in radiation protection education and the provision of personal protective equipment, the registration rate for radiation workers among interns and residents remains low. Ensuring these medical professionals are registered and managed as radiation workers is crucial for prioritizing their safety and well-being.

Properties of cement Portland composite prepared with Barium sulfate and Bismuth oxide for radiation shielding

Radiation is useful but can be harmful to humans if used carelessly. Therefore, radiation protection equipment is necessary for workers. In this paper, we aim to study a cement composite with BaSO4/Bi2O3 for protection against X-rays and gamma rays. The shielding ability was measured using a diagnostic X-ray with energies of 60–120 keV and gamma rays of Cs-137, Ba-133, Co-57 and the morphology structure was determined including radiation protection properties. The results showed that Portland cement with a high concentration of BaSO4/Bi2O3 had the ability to absorb radiation from X-rays in the range of 95.54–99.87% and gamma energy in the range of 93.37–98.88%. Moreover, the composite of BaSO4/Bi2O3 induced a homogenous structure of Portland cement possibly affecting the strength of the material. In addition, Portland shielding can be designed for use in related applications in various energy ranges including ones that are environmentally friendly and suitable for the development of radiation protection in the future.

Effects of Ionizing Radiation Exposure on Cataract among Radiation Workers of Interventional Cardiology in Indonesia

Abstract Purpose The aim of this study was to determine the prevalence of radiation-induced cataracts and its correlation with radiation exposure dose and radiation protection equipment use among radiation workers of interventional cardiology. Methods This is a cross-sectional and retrospective case–control study. We included 180 subjects. The prevalence of radiation-induced cataracts was assessed using Scheimpflug analysis on the Pentacam-Oculus device. Individual cumulative radiation exposure dose and radiation protection equipment use were identified from questionnaires and personal dosimeters. Results The prevalence of radiation-induced cataracts was 16.7%. The median cumulative radiation dose was 0.8 (0.1–35.6) Gy. A positive correlation was found between cumulative radiation dose and lens density (R Spearman = 0.64). We found 83.9% of subjects used ceiling-suspended shields in 71 to 100% of their working period. However, most subjects (40.6%) did not wear protective eyewear. There was a statistically significant increasing risk of radiation-induced cataracts and unresponsive use of radiation protection equipment. Subjects using ceiling-suspended shield in only 31 to 50% of their working period increased their cataract risk by 10.8 times (95% confidence interval [CI]: 1.05–111.49, p = 0.044). Meanwhile, subjects using protective eyewear in only 51 to 70% of their working period increased their cataract risk by 8.64 times (p = 0.001). Subjects who did not wear protective eyewear had an odd ratio of 164.3 (95% CI: 19.81–1363) compared to those who did. Conclusion Radiation-induced cataracts among radiation workers of interventional cardiology depended on the radiation exposure dose and the use of radiation protection equipment.

Operator Intracranial Dose Protection During Fluoroscopic-Guided Interventions.

We utilized an anthropomorphic model made with a human skull to determine how different personal protective equipment influence operator intracranial radiation absorbed dose. A custom anthropomorphic phantom made with a human skull coated with polyurethane rubber, mimicking superficial tissues, and was mounted onto a plastic thorax. To simulate scatter, an acrylic plastic scatter phantom was placed onto the fluoroscopic table with a 1.5mm lead apron on top. Two Radcal radiation detectors were utilized; one inside of the skull and a second outside. Fluoroscopic exposures were performed with and without radiation protective equipment in AP, 45-degree RAO, and 45-degree LAO projections. The skull and soft tissues reduce intracranial radiation by 76% when compared to radiation outside the skull. LAO (308.95 μSv/min) and RAO projections (96.47μSv/min) result in significantly higher radiation exposure to the primary operator when compared to an AP projection (54 μSv/min). All tested radiation protection equipment demonstrated various reduction in intracranial radiation when compared to no protection. The hood (68% reduction in AP, 91% LAO, and 43% in RAO), full cover (53% reduction in AP, 76% in LAO, and 54% in RAO), and open top with ear coverage (43% reduction in AP, 77% reduction in LAO, and 22% in RAO) demonstrated the most reduction in intracranial radiation when compared to the control. All tested equipment provided various degrees of additional intracranial protection. The skull and soft tissues attenuate a portion of intracranial radiation.

A Review of Radiation Protection Standards for Workers in Hospital Radiology: A Narrative Literature Review

One of the goals of radiation protection is to prevent stochastic effects from occurring and to limit the chances of stochastic effects occurring to a limit value that is acceptable to society. This literature review aims to describe radiation protection standards for workers in hospital radiology. To prevent non-stochastic effects, a limit of 0.5 Sv (50 rem) in 1 year was used for all tissues except the lens of the eye. For eyepieces, the recommended annual limit is 0.15 Sv (15 rem). This limit value is used either for radiation reception by a single tissue or for radiation reception by multiple organs. To limit stochastic effects, the annual effective equivalent dose (HE) limit for whole-body radiation reception is 50 mSv (5 rem). The radiation protection equipment that must be available at a radio diagnostic facility is a lead apron, thyroid shield, gonad protectors, gloves, Pb goggles, and lead curtains. In conclusion, radiation protection equipment must be provided by radiology facility operators and used by radiation workers, especially radiologists and other competent doctors. Periodic inspection and standardized maintenance of radiation shields must be carried out for the sake of public safety.

A follow‐up questionnaire survey 2022 on radiation protection among 464 medical staff from 34 endoscopy–fluoroscopy departments in Japan

We surveyed and reported low protective equipment usage and insufficient knowledge among endoscopy-fluoroscopy departments in Japan in 2020. Two years later, we conducted a follow-up survey of doctors, nurses, and technologists in Japan. We conducted a questionnaire survey on radiation protection from May to June 2022. The participants were medical staff, including doctors, nurses, and radiological and endoscopy technicians in endoscopy-fluoroscopy departments. The questionnaire included 17 multiple-choice questions divided into three parts: background, equipment, and knowledge. We surveyed 464 subjects from 34 institutions. There were 267 doctors (58%), 153 nurses (33%), and 44 technologists (9%). The rate of wearing a lead apron was 98% in this study. The rates of wearing a thyroid collar, lead glasses, and radiation dosimeter were 27%, 35%, and 74%, respectively. The trend of the protective equipment rate was similar to that of our previous study; however, radiation dosimetry among doctors was still low at 58%. The percentage of subjects who knew the radiation exposure (REX) dose of each procedure was low at 18%. Seventy-six percent of the subjects attended lectures on radiation protection, and 73% knew about the three principles of radiation protection; however, the concept of diagnostic reference levels was not well known (18%). Approximately 60% of the subjects knew about the exposure dose increasing cancer mortality (63%) and the 5-year lens REX limit (56%). There was some improvement in radiation protection equipment or education, but relatively little compared to the 2020 survey of endoscopy departments.

Determination of scattered radiation dose for radiological staff during portable chest examinations of COVID-19 patients.

The COVID-19 pandemic has resulted in a large increase in the number of patients admitted to hospitals. Radiological technologists (RTs) are often required to perform portable chest X-ray radiography on these patients. Normally, when performing a portable X-ray, radiation protection equipment is critical as it reduces the scatter radiation dose to hospital workers. However, during the pandemic, the use of a lead shield caused a heavy weight burden on workers who were responsible for a large number of patients. This study aimed to investigate scatter radiation doses received at various distances, directions, and positions. Radiation measurements were performed using the PBU-60 whole body phantom to determine scatter radiation doses at 100-200cm and eight different angles around the phantom. The tests were conducted with and without lead shielding. Additionally, the doses were compared using the paired t test (p < 0.005) to determine suitable positions for workers who did not wear lead protection that adhered to radiation safety requirements. Scatter radiation doses of all 40 tests showed a highest and lowest value of 1285.5 nGy at 100cm in the anteroposterior (AP) semi upright position and 134.7 nGy at 200cm in the prone position, respectively. Correlation analysis between the dosimeter measurement and calculated inverse square law showed good correlation, with an R2 value of 0.99. Without lead shielding, RTs must stay at a distance greater than 200cm from patients for both vertical and horizontal beams to minimize scatter exposure. This would allow for an alternative way of performing portable chest radiography for COVID-19 patients without requiring lead shielding.

Integrity of personal radiation protective equipment (PRPE): a 4-year longitudinal follow-up study

BackgroundPersonal radiation protective equipment (PRPE) such as lead aprons minimises radiation exposure of operators using X-ray systems. However, PRPE might be prone to cracks in the attenuating layer resulting in inadequate radiation protection. This study aims to investigate the prevalence, qualification and quantification of PRPE integrity during a longitudinal follow-up study.MethodsAll PRPE of a large, general hospital was evaluated yearly in the period 2018–2021. The equipment was inspected on a tele-operated X-ray table, and tears were qualified and quantified using an X-ray opaque ruler. Rejection criteria of Lambert & McKeon, with an extra rejection criterion of 15 mm2 for individual tears, were applied to accept or reject further use of the PRPE.ResultsOver the 4-year follow-up period, a total of 1011 pieces of PRPE were evaluated. In total, 47.3% of the PRPE showed tears of which 31% exceeded the mentioned rejection criteria. Remarkably, of the 287 newly registered pieces of PRPE, 6.0% showed tears in the first year of use of which 88.2% needed to be rejected. Also, 48% of the repaired PRPE was rejected again in the consecutive year.ConclusionsPRPE is prone to cracks. Up to 50% of PRPE showed tears and cracks resulting in 31% rejections. Newly purchased PRPE is not guaranteed to remain free of cracks and tears in the first year of use. Repair does not guarantee a long-term solution for prolonging the lifespan. Regular X-ray-based integrity analysis of PRPE is needed to ensure adequate radioprotection for operators using X-ray systems.

Radiation protection during fluoroscopic interventions

Facts and figures about the frequencies of fluoroscopically guided interventions (FGI), typical patient exposures and occupational exposures are listed. Limits of radiation exposure do not exist for patients but only for occupationally exposed medical personnel. Measures for radiation protection of patients and personnel are explained. Nearly all technical radiation protection measures for patients also protect the personnel. To reduce the exposure of medical personnel, radiation protection equipment should be attached to the X‑ray modality and personal radiation protection equipment should be worn. The diagnostic reference values and the obligation to report incidents, including the reporting criteria, are explained. The radiation protection of patients and personnel for FGI in Germany is well regulated by diagnostic reference values, reporting criteria, prescribed or recommended protective measures, personal dosimetry and the obligation to involve medical physics experts.

APRON QUALITY TEST FOR OPTIMIZATION OF RADIATION PROTECTION FOR PATIENTS IN RADIOLOGY OF DIAGNOSTIC AND INTERVENTIONAL

APRON QUALITY TEST FOR OPTIMIZATION OF RADIATION PROTECTION FOR PATIENTS IN RADIOLOGY OF DIAGNOSTIC AND INTERVENTIONAL. Apron is a body protective device that can reduce the dose of scattered radiation exposure from x-ray beams, but in the use of an apron it is often neglected because of impracticality and improper laying procedures that cause damage to the lead rubber plate (Pb) inside so that the function of apron in protecting radiation is not optimal and most likely to get high dose from scattered radiation. This test aims to ensure that radiation protection equipment can provide optimal protection. The apron quality test methods analyzed were visual, tactile and fluoroscopy. In addition, the analysis of the quality of the apron is evaluated by looking at the level of damage and reviewing the graph of the relationship between area of defect and equivalent dose. The results of the radiation dose measurement based on the irradiation process on the apron in the radiology room there was 1 damaged apron of 3 aprons, while in the ESWL room there were 1 apron and in the cathlab room there were 4 aprons still in good condition. Based on the level of damage to the apron in the radiology room, there were several types of damage, namely absent lead type = 1.75 mSv, Crack type = 0.67 mSv and stiching type = 0.47 mSv. The results of the graph between the dose equivalent to the area of defect obtained a linear relationship, meaning that the more extensive the damage to an apron, the greater the radiation dose received by the patient and the patient's companion. Therefore, for the apron that is not feasible, based on the dose and area, it is better to replace the apron so that providing optimal protection and prevent unnecessary exposure.

SIMULATION OF MOBILE X-RAY EXPOSURE TEST ON CHEST X-RAY EXAMINATION AT FATMAWATI HOSPITAL

SIMULATION OF MOBILE X-RAY EXPOSURE TEST ON CHEST X-RAY EXAMINATION AT FATMAWATI HOSPITAL. Chest X-ray examinations using mobile X-rays are increasing, especially due to the Covid-19 pandemic as an early detection as well as for patient monitoring needs. Radiation safety aspects in chest X-ray examinations using mobile X-rays need to be studied considering that they are generally used in patient inpatient rooms. This study aims to simulate the amount of scattered radiation from a chest X-ray examination using a mobile X-ray to assess the level of radiation safety and the required radiation protection equipment. First, the primary radiation dose was measured to assess the estimated dose received by the patient, then the scattering radiation was measured (maximum dose rate and accumulated dose) using 20 cm PMMA phantom scattering media in various directions at a distance of 1, 2, 3 and 4 m. and with variations without radiation shielding, with 0.5 mm Pb apron radiation protection and with 2 mm Pb mobile shielding. The result of the primary radiation dose is 0.145 ± 0.003 mGy, which is still below the DRL value. While the dose rate analysis results show that up to a distance of 4 m the dose rate value still exceeds the radiation safe limit, a radiation protection is needed in the form of a 0.5 mm Pb apron with a distance of more than 2 m in order to obtain a safe dose rate for the general public. The results of the analysis of the accumulation of scattered doses, the safe distance without using radiation shields is more than equal to 2 m. It is recommended that the patient and staff distance from the mobile X-ray radiation source is at least 2 m and use a radiation protection such as Pb apron or mobile shielding.

Efficiency evaluation of leaded glasses and visors for eye lens dose reduction during fluoroscopy guided interventional procedures

PurposeFluoroscopy guided interventional procedures guarantee high benefits for patients, but are associated with high levels of radiation exposure for the medical staff. Their increasing use and complexity results in even higher radiation exposures, with a risk to exceed the annual dose limit of 20 mSv for the eye lens. The aim of the study was to evaluate the potential dose reduction of eye lens exposure for lead glasses and for two types of visors (half and full), used by physicians performing interventional procedures. MethodsEye lens dose measurements were carried out on an anthropomorphic phantom simulating a physician performing a fluoroscopy guided interventional procedure. Dose reduction factors were calculated using high sensitivity thermoluminescent dosimeters. Moreover, a spatial dose distribution was generated for the two visors. ResultsThe dose reduction coefficient was found to be 1.6 for the glasses, 1.2 for the half visor and 4.5 for the full visor. ConclusionsOptimal radiation protection requires a combination of different radiation protection equipment. Full visors that cover all the face of the operator are recommended, as they absorb scattered radiation reaching the eyes from all directions. Full visors should be prioritized over radiation protection glasses for cases where other protective equipment such as ceiling shielding cannot be used.

Monitoring and Protection against Radiation Dose to Eyes of Operators Performing Neuroendovascular Procedures: A Nationwide Study in Japan.

To meet the new standard of the annual dose limit for the eye lens recommended by the International Commission on Radiation Protection, radiation doses of neuroendovascular procedures in Japanese institutions were investigated. Radiation doses to operators involved in 304 neuroendovascular procedures at 30 Japanese institutions were prospectively surveyed. The institutions recruited at an annual meeting of the Japanese Society for Neuroendovascular Therapy participated voluntarily. A maximum of 10 wireless dosimeters were attached to the radiation protection (RP) goggles, the ceiling-mounted RP shielding screen, and the operators' forehead and neck over the protective clothing. Doses recorded inside the goggles were defined as eye lens doses for operators who wore RP goggles, while doses to the forehead were defined as eye lens doses for those who did not. The shielding effect rates of the protection devices were calculated, and statistical analysis was performed for the comparison of radiation doses. From 296 analyzed cases, mean eye lens radiation doses per procedure were 0.088 mGy for the left eye and 0.041 mGy for the right eye. For the left eye, that dose without RP equipment was 0.176 mGy and that with RP goggles plus an RP shielding screen was 0.034 mGy. Four parameters, including left eye dose, air kerma at the patient entrance reference point, fluoroscopic time, and the total number of frames, were assessed for five types of neurovascular procedures. Of them, transarterial embolization for dural arteriovenous fistula was associated with the highest eye lens dose at 0.138 mGy. The shielding effect rates of protection goggles were 60% for the left and 55% for the right RP goggle. The mean doses to the inner and outer surfaces of the RP shielding screen were 0.831 mGy and 0.040 mGy, respectively, amounting to a shielding effect rate of 95%. To meet the new standard, both RP goggles and RP shielding screens are strongly recommended to be used effectively. Without proper use of radiological protection devices, the number of neuroendovascular procedures that one operator performs per year will be limited under the new guideline.
