Abstract: A method employing radioactive kryptonates as the end point indicators in chelatometric titrns. was described. The end point is detd. with the solid radioactive kryptonate AB[85Kr], added to the soln. before the beginning of the titrn. After the end point is exceeded, the excess of the added chelate-forming agent reacts with the radioactive kryptonate liberating radioactive 85Kr.  Principles of the titration method, methods for preparing radioactive kryptonated indicators, experimental results of kryptonation and a study of the properties of prepared radioactive kryptonates from the point of view of their application as indicators in radiochelatometrie titrations are given in this paper.
