An alternative approach for the excess lifetime cancer risk and prediction of radiological parameters

Abstract

Abstract As one of the most important parameters to express radiation's harmful effects is excess lifetime cancer risk, which is presented in the literature with the empirical relationship, an alternative association was developed for excess lifetime cancer risk in this study. This relationship included radiological risk parameters and the average life expectancy and also does not require a coefficient recommended by organizations. The selected area is Çünür district of Isparta province in Türkiye, which is approximately 12.5 km2. The gamma-ray spectrometry studies were carried out at 270 different points. In this study, the radioactive elements (U, Th, and K) are directly measured on the geological materials (trachyandesite, flysch, limestone, and soil) using a gamma-ray spectrometer device. Maps were created to compare the outcomes of excess lifetime cancer risk determined with the new approach and calculated using the existing relationship in the literature. Also, the calculated radiological risk parameters were mapped to evaluate the study area in general. In addition to these, the relationships between each other radioactive elements and the relationships between the radioactive elements and the radiological risk parameters were investigated.
