Soil radioactivity atlas of Kuwait

摘要

Background radionuclide concentrations in surface soil (5 cm loop) across Kuwait were measured by gamma spectroscopy with a HPGe detector. These measurements were made as part of program for assessment of radiation doses from natural sources for the Kuwait population. The sampling program provided background information at 83 sites in different geological formations. The nationwide average concentrations in Bq/kg were as follows: for ~40K-332 ±104 Bq/dg (arithmetic 50), for ~226Ra-118±4.0 Bq/kg, for ~238U-13.±5.0 Bq/kg, for ~232Th-10.0±3.4 Bq/kg, and for ~137Cs-2.6±2.6 Bq/kg.
