Description

Geological survey performed in the coastal region of the northeast of Brazil revealed the presence of uranium phosphate deposits in a land strip covering the Pernambuco-Bahia sedimentary basin. The water consumed by the local population crosses the phosphate area and presents higher tna normal concentration of uranium and its progeny. This work is aimed to determine the cancer risk, based on the rate ingestion of the 222'Rn due to water consumption. The results of the analysis showed increments of 1.25% for cancer occurrences due to Rn-222 ingestion for the local population. (author). 11 refs., 1 fig., 1 tab
