| determination of radioactivity levels and heavy metal concentrations in seawater, sediment and anchovy (engraulis encrasicolus) from the black sea in rize, turkey. | seawater, sediment and fish (anchovy) samples consumed in the rize province of the eastern black sea region of turkey were collected from five different stations. the radioactivity levels ((226)ra, (232)th, (40)k and (137)cs) were determined in all the samples using a high-purity germanium detector. while (226)ra, (232)th and (40)k radionuclides were detected in all samples, the radionuclide concentration of (137)cs, except for the sediment samples (mean activity is 9±1.4bqkg(-1)), was not detec ... | 2017 | 28081960 |
