This study aims to estimate the radiological impact on the environment (RIE) from the release of water treated by the ore processing unit (UTM) at Caldas, MG, during the years 2005 and 2006. In 2005, the UMT operated 400 tons of monazite in a process to obtain rare earths; during the following year there was no industrial process. The effluent waters were tested once a week for points 014 and 025, and once a month for point 076. The critical radionuclides are U-238, Ra-226, Pb-210, Th-232 and Ra-228. U-238 and Th-232 were analyzed by spectrophotometry. Ra-226, Ra-228 and Pb-210, in turn, were analyzed by chemical separation and radiometric methods. The dose estimates were based on the model proposed by the National Commission of Nuclear Energy.
