In Situ measurements of gamma background in areas of coal power plants on the territory of Bosnia and Herzegowina

In this paper results of measurements specific activity and exposure rates of gamma rays on 1 m above ground in areas of 4 coal power plants in BiH are explained. Measurements with the equipment for field gammaspectrometry done at 4 points: in the room in the coal power plant, 3-5 km in direction, 3-5 km inverse of direction of wind and depository of ash. From found gamma specters accounted specific activity and exposure rates gamma rays for most important natural (U-238, Th-232 and K-40) and artificial (Cs-137 and Cs-134) radionuclides. (author)
