Data on the uptake and retention of Ra and Pu in ocular tissues are reviewed. These data were used to calculate alpha radiation doses to the lens of the eye for patients injected with /sup 224/Ra and for individuals exposed to one annual limit on intake (ALI) per year of /sup 224/Ra, /sup 226/Ra, /sup 228/Ra and /sup 239/Pu for a period of 50 y. On the basis of this analysis, it is concluded that the induction of lens opacity should not be the factor limiting intake of any radioisotope of Pu or for /sup 224/Ra or /sup 226/Ra. However, for /sup 228/Ra the dose lies within the range of doses received by /sup 224/Ra patients who have developed cataracts.
