Radiometric monitoring outdoor municipality Pocinhos-PB

Studies on human exposure to terrestrial radionuclides are important for human health. Therefore, this investigation presents aimed at making radiometric dosimetry Pocinhos municipality in the state of Paraiba. Monitoring was performed in 50 points in urban and rural areas Pocinhos. The estimated external effective dose rate in outdoor environments was obtained in triplicate using a portable gamma spectrometer, to 1.0 m away from the Earth's surface and time set acquisition in terms of environmental radiation levels. The values of these dose rates outdoor environments ranging from 0.53 to 3.94 mSv.y^-1. the arithmetic mean was 0.79 mSv.y^-1, which exceeds the value 0.07 mSv.y^-1 corresponding to the global average in outdoor environments. In the city, found a higher radioactivity in rural areas that were uninhabited at the time of the survey. (Author)
