Risk to Krakow Population of gamma Irradiation from Building Materials
Statistics were made of 7128 dwelling-houses considering their age, types of building materials and density of population. Gamma dose rates were measured by means of the TL and pressurized ionization chamber techniques inside 300 buildings and at 44 points outdoors over different kinds of beddings. Personal doses of 49 inhabitans of the buildings monitored were also recorded. By means of the spectrometric analysis of gamma radiation, and basing on a specially developed computational programme ''DOZA'' mean concentrations of exp 40 K, exp 226 Ra and exp 232 Th in 61 samples of building materials were evaluated. It was found that the mean personal dose rate as well as the mean indoor dose rate equals 5.7 mu rad/h (15.8 pGy/s) and is about 19% higher than the dose outdoors which equals 4.8 mu rad/h (13.3 pGy/s). Gamma dose rates inside the buildings made of gravel-sand concrete elements are about 10% lower than those in the buildings made of red bricks. (Atomindex citation 12:605153)
