In the present study, the transfer factors of the natural radionuclides 238 U, 232 Th, and 40 K
were estimated for several crops cultivated in farms in the suburbs of Baghdad and one farm …

The main objective of this study was to assess the natural radiation dose and radiological
risk around Lake Monoun and some surrounding localities. A total of 28 soil samples were …

The specific activities of natural radionuclides, 232Th, 226Ra, and 40K, in a Chinese iron
beneficiation plant and surrounding soil were analyzed with the high purity germanium …

This study considers the contents of natural radionuclides (226Ra, 232Th, and 40K) in the
soils of natural–technogenic landscapes in the Verkhnekamskoe potassium–magnesium …

Natural radioactivity mainly consists of U series, Th series, and K in soil and rocks. This
study focuses on determining natural radioactivity concentrations and radiological hazard …
