چکیده انگلیسی
Distributions of natural gamma-emitting radionuclides were determined in 93 oil samples collected from some petroleum fields in the western desert of Egypt. The radioisotope activities in the area under investigation lay in the range of (21 ± 4) to (38 ± 13) Bq·Lâ1 for 226Ra, (9 ± 2) to (15 ± 5) Bq·Lâ1 for 232Th, and (154 ± 28) to (303 ± 54) Bq·Lâ1 for 40K. The mean values were 27, 12, and 201 Bq·Lâ1, respectively. Among oils, variations in radionuclide activities could be on account of differences in TDS, HCO3, and Ba, with high or low pH. In this environment, oil properties differently affected the mobilization of natural radionuclides. The range of 226Ra variation had been compared with available data from other countries. The calculated absorbed dose rate ranged from 22.33 to 32.66 nGy·hâ1 in location (B) and (E) respectively, which was less than the accepted value.
