A review is preserted of milking systems for separating a desired radioisotope from its parent and other contaminants. Milking systems are considered for the separation of the following radioisotopes: Zr/sup 95/ from Nb/ sup 95/, I/sup 132/ from Te/sup 132/, La/sup 140/, from Ba/sup 140/ Ba/sup 137/ from Cs/sup 137/ Y/sup 90 / from Sr/sup 90/ Tc/sup 99m/ from Mo/sup 99/, Ga/sup 68/, from Ge/sup 68/, Al/sup 28/ from Mg/sup 28/, etc. (D.L.C.)

Three groups of 12 mice each were maintained at environmental temperatures of 34, 22, and 5 deg C for a period of about 7 weeks after an intraperitoneal injection of Cs/sup 137/. Periodic assay of the activity in the whole body and excreta showed that as environmental temperature decreases the excretion of Cs/sup 137/ increases, probably as a result of the increased metabolic rates associated with low temperatures.
