The Radioactivity measurement of Turkish Lignites

摘要

This is a study on the radioactivity of Turkish lignites in which the gamma spectrometric technique has been used for the determination of activity levels of naturally occurring radionuclides ~238U, ~232Th, ~40K, ~226Ra and fallout radionuclides ~137Cs and ~134Cs in lignites taken from 12 different parts of Turkey by the Mineral Researh and Exploration Institute of Turkey. Concentrations of ~237U, ~232Th, ~226Ra, ~40K, ~137Cs and ~134Cs were found up to 52, 37, 207, 163 Bq kg~-1, LLD, ND, respectively.
