Radiation sensitivities of B.ponilus and B.subtilis spores were examined to breasstrahlung of 5 P1eV lB and Cobalt-60 y rays in order to confirm the effects of radiation and dose rate. Biological indicators (SPORTROL,NA.SA,USA) were irradiated with the X ray in the dose rate range of 4.7-47 k(y/h. D-value of B.pusilus spores was 1.4-1.5 kGy, and that of B.subtilis was 1.1-1.3 kGy. The U-values of B.po.ilus and B.subtilis have very small dose rate dependences to X ray, and the U-values are similar to those of y ray. Dose distribution by X-ray and y irradiation was measured for cartons containing 32 unit dialyzers. The D.ax./D..in. of the X-ray irradiation (1.2) was smaller than that of V ray (1.3).
