The natural gamma radiation and 137Cs deposit in the soils of Bansko-Razlog region was measured, using high-resolution gamma ray spectroscopy. The resulting annual effective dose was estimated to be 0,32 mSv, that is very lower than the level of 1 mSv adopted as the upper annual dose limit for the population in Bulgaria. The study area is intensive winter resort which is frequented by many Bulgarian and foreign tourists.
