摘要

The aim of this study was to evaluate the artificial and natural radiation dose levels in the coastal areas of Trabzon–Rize–Artvin provinces 38 years after the Chernobyl nuclear accident. Radioactive 232Th, 238U, 40K and 137Cs concentrations were determined in 49 soil samples by HPGe gamma spectrometry. Average concentrations were 12 Bqkg−1 for 238U, 15 Bqkg−1 for 232Th, 162 Bqkg−1 for 40K and 37 Bqkg−1 for 137Cs. Annual effective dose equivalents and excess lifetime cancer risk values are below the world average. This study also presents the average 137Cs value measured in the same area from 1990–2004–2024.
