From meeting of the Gesellschaft Deutscher Chemiker on trace analysis; Erlangen, Ger. (2 Apr 1973). A new method for the separation of recoil atoms produced by the decay of /sup 224/Ra was developed by applying alkyl radicals. Argon was used as carrier gas and the transported alkyl compounds thermally decomposed in front of a Ge(Li) detector. Under the experimental conditions /sup 212/Pb and /sup 212/Bi could be transported wi th high yields whereas transport of /sup 208/Tl could not be proved. There was no interference of the measurements by /sup 220/Rn. Using /sup 252/Cf as a source for fission products the recoil atoms were stopped in argon (about 4 atm). The thermalized recoil products were mixed with alkyl radicals and the possibly formed alkyl compounds were thermally decomposed in front of a detector. In the experiments with pure argon as inert gas high yields of iodine were found. (GE)
