Survey of radium-226 content and radon-222 exhalation rate in sediments from Gharaf River in Thi Qar, Iraq

Abstract

Since radionuclides in sediment transference contribute to total collective dose, and because it is little published data about radionuclides in Gharaf river sediments in Thi Qar province, Iraq. So, it is studied effective radium content (ERC), area exhalation-rate (AER) of radon and mass exhalation-rate (MER) of radon in sediments of Gharaf river and its creeks (GRC) in Thi Qar, this paper might be helpful for monitoring any possible pollution, obtain a data-base for future studies, and to supplement the radiation map of Iraq. Results are displayed and compared with the recommended-limit by OECD, UNSCEAR and previous studies.
