This Note can thereafter be cited when dealing with vegetation and soil. N-9 The external gamma-ray exposures of Table 4.1 #l affect all of the tissues of the body. In addition, beta rays (cesium-137 and strontium-90) emanate from soil, but have only a limited range in they might affect the air and very poor penetration into the body; body’s surface in those regions which are closest to or are actually touching the ground. Shoes and clothing provide complete or almost complete protection. External beta-ray dose is considered to be unimportant on the basis of the following. For gamma rays, the Rongelap Island/Eneu Island external-dose ratio is 1.6 (Table ). The beta-ray dose ratio at .007 mm depth (basal cell layer, skin) should be approximately the same. by extrapolation from the Therefore, determinations at Eneu (Singleton et al) the Rongelap basal-cell dose would be 46 mrem/y, and at 1 cm depth practically zero (ICRP 51, Table 26). Since the radiation protection guide for skin is 5 (NCRP 1987b), the skin dose is a trivial one. rem/y Query: I/here does the citation go?
