eS were added for each intake of fallout material- “Step 1. Determine the sr89 to reach the bone. According to reference };: The sr89 content in mixed fission products on the 120th hour is 1.6%. According to reference 5: The intake of sr89 to reach to the bones is 25%. Therefore: (27) (0.016) (0.25) = 0.108, to the bone. Step 2. Determine the dose rate to the bones.

The solubility of fallout material varies, depending among other factors upon the surface over which the detonation occurred. The fallout material collected in soil samples at the Nevada Test Site has been quite insoluble, i.e. only a few percent in distilled water and roughly 20=30 percent in 0.1 N HCL. However, it would be expected that the activity actually present in - 7 DOE ARCHIVES
