Abstract |
|
|
| The concentrations of various radionuclides in fishbones of seven fish inhabiting nine different locations in the Eastern Coastline of Libya are investigated, a distance of about 500 km. These fish are: Epinephelus Marginatus (S1), Pagellus Bogaraveo (S2), Diplodus Vulgaris (S3), Umbrina Cirrosa (S4), Trachurus Mediterraneus (S5), Balistes Carolinensis (S6) and Seriola Dumerili (S7). Assessment was made of the concentration activities of key indicator natural radionuclides, especially 40K, 226Ra, 234Th and 235U, using HPGe detector. The radioactivity concentration (in Bq/kg) ranged from 27.90±0.15 for S3 to 255.00±0.02 for S7 for 40K; from 1). It is concluded that this increase may be of concern to consumers of this type fish. |
