Abstract

It is important to determine the relative radiation doses in those tissues in which biological effects have been observed or suspected in humans (Sp78; Sp79). The animal experiments described here were performed in order to obtain data which could provide some indications for the dosimetry of short-lived 224-Ra in man. The percentage of total injected 224-Ra retained after either pure 224-Ra or peteosthor application was highest in the skeleton (42-48%). A minor amount was found in the eyes (0.6-0.7%), and even less in kidneys, spleen and liver (Fig.1). Retention of injected platinum (as percentage of total injected amount) was highest in the liver (about 23%). Only traces of platinum were present in the eyes (Fig. 2). No platinum could be identified in the skeleton but, as shown above, it is less than 10%.
