ABSTRACT
The underground exploitation of the ores established many waste dumps. The mineralization with pechblenda, the main uranium ore, exists in lenticular layers of small thickness. The rocks with uranium mineralization recover in the waste dumps, increasing the level to the ionizing radiation exposition. In Tincota the radiation levels found where between 50 and 600 c/s, with maximum levels 600-1200 c/s in the waste dump. The road DJ 680 Caraşova-Voislova are the levels 800-1200 c/s, that is 2-3 times more than the dose accepted in the Norms. The magnetite are from Boul Peak is associated with a radioactive ore (brannerit) and the road Ruschiţa-Voislova was contaminated, the levels at the flotation base near the road reached times more than normally.
