Summary
Using a variety of biological materials and end points, it was found that the radiation dose of 200-kvp x rays required to produce a given observable effect is about 0.90 the dose of Co/sup 60/ gamma rays or 22 Mevp x rays required to produce the same effect. The gamma rays and 22 Mevp x rays were found to be equally effective. The biological end points used included the mean lethal dose for mice, rats, yeast, and chick embryo; depression of Fe/sup 59/ uptake of the erythrocytes of rats; and chromosome damage in mouse ascites tumor cells. Progress is reported in studies of reaction mechanisms involved in the explanation of rela tive biological effects and problems related to radiation dosimetry. (C.H.)
