Monitoring and assay procedures for krypton-85 used in circulatory tests

Abstract

During the past five years, krypton-85 has been used extensively at the National Institutes of health and by the heart Catheterization laboratory in the identification of circulatory shunts. Several methods of assaying the incoming shipments of radioactive gas are given. These consist of ionization chamber measurements, gamma ray spectrometry, and gross photon counting of the cylinder surface with an end-window Geiger-Mueller tube. A device (consisting of a log-count-rate meter, recorder, and G.M. tube) is used to continuously monitor the laboratory. The method of calibrating this device is presented. A means for removing contaminated air from the vicinity of the operating table was devised. The results of air clearance studies of the room are included. (auth)
