The Dependence of late effects in mice on the temporal distribution of skeletal α-doses from 224Ra a female NMRI mice 4 weeks old at the start of the experiment. Their mean spontaneous osteosarcoma incidence is 0.7%. Osteosarcomas of the jaws were excluded from the evaluation or considered separately. The radionuclides were injected intraperitoneally as isotonic solutions..Dosimetric data for .Ra

The maximum osteosarcoma incidences observed in this series were 84% (total mean skeletal dose 2160 rad, maximum dose rate 24 rad/day, treatment period 24 weeks) and 93% (total mean skeletal dose 1080 rad, maximum dose rate 8 rad/day, treatment period 36 wee

Quality control in the production process and purity of 224Ra for injectiond..We compare the detected long-lived radioactive impurities in 280 μCi .Ra injection-solutions with the maximum values accepted by ICRP. The actual amounts of impurities present are less than 0,2% of the permissible doses recommended by ICRP..The .Ra solution is sterilised in an autoclave to a stan
