Abstract
The behavior of radon in marine sediments collected from Abian beach, Abian Governorate, Aden Gulf, Yemen, was studied by using Alpha Guard PQ2000 PRO radon detector. The activity concentration of radon in the sediments was found to be ranging from 64.84 to 166.93±11.85Bq.m<sup>-3</sup> with mean value 103.88±8.80Bq.m<sup>-3</sup>. The radium content in the sediments ranged from 20.01 to 56.06Bqkg<sup>-1</sup> with mean value 33.51Bqkg<sup>-1</sup>, while the area exhalation rate of <sup>222</sup>Rn ranged from 6.73 to 18.49Bqm<sup>-2</sup>h<sup>-1</sup> with mean value 11.22Bqm<sup>-2</sup>h<sup>-1</sup> also the mass exhalation rate of <sup>222</sup>Rn ranged from 0.151 to 0.424Bqkg<sup>-1</sup>h<sup>-1</sup> with mean value 0.253Bqkg<sup>-1</sup>h<sup>-1</sup>, respectively for the studied samples of marine sediments. The annual effective dose was found to be ranging from 1.63 to 4.21mSvy<sup>–1</sup>, with an average of 2.62mSvy<sup>–1</sup>. Average value of radon concentrations from marine sediments samples were compared with other literature values.
Highlights
226Ra is a radioactive element existed in soil, rock, sand, water, animals and plants. 226Ra has entered the human body from the soil by vegetarian food, its concentrated in the bones
The activity concentration of radon gas ranged from 64.84 to 166.93 Bq.m-3 with mean values 103.88±10.2 Bq.m-3 the mean value of the activity concentration of radon is lower than the worldwide value of 300Bq/m3, which is given in IAEA, 2018, and the annual effective dose ranged from 1.63 to 4.21mSvy– 1 with mean value 2.62±1.621mSvy–1
The concentrations of radon in the marine sediment samples collected from the Abian beach have been measured directly; using Alpha guard technique and the radon annual effective doses ERn have been calculated
Summary
This led to bombard the bone marrow and mutate tissue. Radon decays into its daughters giving tiny radioactive particles. When inhaled, these radioactive particles can damage the cells that line the lung.
