摘要：

The radioactivity levels of Istanbul environs lignites were determined. The gamma-spectrometric technique has been used for the determination of activity levels of naturally occurring radionuclides 235+238U, 228+232Th, 40K, 226Ra and fallout radionuclides 137Cs in lignites taken from 7 different parts of Istanbul. Concentration of 238U, 228+232Th, 40K, 226Ra 137Cs and 235U were found up to 1.6 ppm, 1.7 ppm, 4.9 ppm, 56.8 Bq/kg, 34 Bq/kg, 1.8 Bq/kg, 1.6 Bq/kg, respectively. In addition total alpha- and beta-activity levels in lignite samples were found to be 7.6 and 15 eps, respectively.
