测定了波兰西南部地区成年人通过食物和水摄入的铀系和钍系天然放射性核素的情况，该地区在1950年代进行了铀矿勘探。在食品和饮用水中测定了放射性核素的浓度，并根据年平均消费量估计了其年摄入量。238 U、234 U和230 Th的摄入主要来源于水（33%~ 68%），而232 Th、228 Th和226 Ra的摄入主要来源于蔬菜、土豆、牛奶和面粉。根据摄入量和剂量系数，计算了摄入放射性核素的年有效剂量。总剂量为5.6 μSv，其中74%来自226 Ra。
Intake with food and water of the natural radionuclides of the uranium and thorium series was determined for adult population of the south-western region in Poland, where in the 1950-ies an exploration of uranium ore was conducted. Concentration of the radionuclides was determined in food products and drinking water and their annual intake was estimated on the basis of the average annual consumption. The intake of238U,234U and230Th occurred mainly with water (33% to 68%), whereas the intake of232Th,228Th and226Ra was mainly with vegetables, potatoes, milk and flour. From the intake and dose coefficients the annual effective doses from the ingested radionuclides were calculated. The total dose was 5.6 μSv, of which 74% originated from226Ra.
