The Brazilian town of Santana do Matos is located in a region which is rich in granites and other pre-Cambrian rocks. Radiological measurements performed in 43 dwellings by a hand-held scintillometer, gave a mean value of 148 ± 44 nGy h-1. Readings in downtown streets ranged from 200 to 330 nGy h-1. Several radiocative anomalies with high γ-background were also located in the surroundings of that town, where a value of 900 nGy h-1 was recorded in a small cave used as a shelter by some shepherds. Concentrations of naturally occurring radionuclides in seven samples of building materials utilized at Santana do Matos, were determined by a gamma spectrometer. The following mean values were obtained: 226Ra: 40.1 Bq kg-1; 232Th: 68.8 Bq kg-1; 40K: 736 Bq kg-1. |
