Abstract

A method for210Po determination in air is developed which includes sucking of known volume of air through aerosol filter typ AFA-XA, wet combustion of the filter by a mixture of conc. H2SO4 and conc. HNO3, deposition of210Po on nickel plate from hydrochloric acid solution at 90°C. The chemical yield is (90.7±5.4)% and radioisotope purity of the final sample (concerning α-emitters) fully satisfactory. If 3 m3 air is sucked the detection limit is 10−17 Cf210Po/1 air.
