Measurement of Radioactivity concentration of Radioisotopes 228Ac, 212Bi, 214Bi, 214Pb, 212Pb in Phosphate Deposits in the Syrian Coast
Abstract
The concentration of radioisotopes, 228Ac, 212Bi, 214Bi, 214Pb, 212Pb of the natural radiation series was determined by the unit (Bq / kg). By using Gamma Rays Spectrometry, by using NaI(Tl) scintillation. The samples were collected from the areas of phosphate spread in the Syrian coast (Ain Lilon, Al-Muhallabah, Ain Al-Tineh).
These results show that the highest value of the Activity concentration of Lead Pb-214 reached (167.40 Bq / kg) in the sample Al 2 in the Ain Lilon section, and for Lead Pb- 212 was (1671 Bq / kg) in the sample Al 2 in Ain Lilon section as well.
The highest value of the Activity concentration of Bismuth Bi- 214 was (72.89 Bq/ kg) in the sample Al 2 at the Ain Lilon section, and and for the Bismuth Bi-212 was (1157 Bq / kg) in the sample Al 2 in the Ain Lilon section as well.
The highest value of the Activity concentration of Actinium Ac- 228 was (1936 Bq / kg) in the Mh7 sample at the Muhallabah section.
These results show an increase in Activity concentration in the areas of phosphate
