Sludge samples from nine drinking water purification stations in El-Mynia governorate namely Kedwan, Elhawarta, Demsher, Tewa, Ard Sultan, Tokh Elkhel, Abu Flow, Saft Elkhmar and Zohrt Elporgi, were analyzed for its naturally occurring radionuclides (226Ra, 232Th and 40K) by gamma- ray spectrometry system using (sodium iodide NaI (Tl) detector).The results show that the specific activity for 226Ra, 232Th and 40K in range of 6±0.7 to 113±6.7, from 5±1 to 117±5.8 and from 47±4.5 to 412±20.6 Bq Kg-1 respectively. The results indicate that sludge of drinking water purification stations in El-Mynia governorate from large scale do not pose a significant radiological risk. Additionally evaluations have been made of the absorbed gamma dose rate in air and the annual effective dose equivalent.
