Determination of the annual effective dose distribution due to cosmic ray exposure of the Eastern Black Sea Region, Turkey

Abstract

In this study, annual effective dose rate distribution due to cosmic radiation, which constitutes an important part of natural radiation, was mapped in  spatial pixels for three provinces in the Eastern Black Sea region (Artvin, Rize and Trabzon). Cosmic ray-induced annual effective dose calculations were performed based on latitude and altitude changes with EXPACS, an excel-based program. Besides, the effect of cosmic radiation on the population living in the study area was determined. For the entire study area, it was calculated the average effective dose rate from Cosmic radiation as 0.65 mSv y-1 and range as (0.33-1.72) mSv y-1. The average annual collective effective dose rate was determined approximately 508 person-Sv y-1. Besides, the population-weighted average annual effective dose rates were obtained as 449, 376 and 370 for Artvin, Rize and Trabzon provinces, respectively.
