Abstract

Based upon present ideas of physical-chemical properties of polonium and its up-to-date determination techniques, a technique of 210Po radiochemical determination in urine samples was developed followed by alpha-spectrometry. The technique was tested on 24-hour urine samples collected from the personnel of the branch “Institute of Radiation Safety and Ecology” RSE NNC RK. The range of 210Po absolute activity per a 24-hour urine sample was determined to be 1.8·10-3÷0.12 Bq. 210Po contribution to the total dose of personnel internal exposure was estimated to be equal to 0.3 mSv/year.
