Description/Abstract:
THE CALCULATION OF THE CONCENTRATION OF RU-106-O2 IN AIR THAT AT EQUILIBRIUM WILL RESULT IN AN AVERAGE DOSE RATE OF 0.3 REM/WEEK TO THE LUNG OF MAN IS PRESENTED. SINCE DATA FROM MOUSE EXPERIMENTS ARE USED THE CALCULATIONS ARE EXTRAPOLATED ON THE BASIS OF DIFFERENCES IN ORGAN WEIGHTS AND DO NOT ALLOW FOR DIFFERENCES IN PHYSIOLOGY. THESE CALCULATIONS NECESSARILY ASSUME UNIFORM DISTRIBUTION OF RU-106 THORUGHOUT THE LUNG TISSUE ALTHOUGH IT IS KNOWN THAT RU-106 IS RETAINED AS PARTICULATES FOLLOWING INHALATION OF INSOLUBLE RUTHENIUM OXIDE PARTICLES. AN MPC (AIR) OF 5 X 10-9 MICRO CURIE/ML OBTAINED USING EXPONENTIAL FUNCTIONS AT REPRESENT RETENTION IS COMPARED WITH 8X10-9 MICRO CURIE/ML OBTAINED USING POWER FUNCTION EQUATIONS.
