GRITERTSV . Lontamination of Water, Air cng Foadstutts In any area where the theoretical gamma infinity dose exceeds 10 roentgens, sdequate sampling of the water, eir, and foodstuffs should be rade to ascertain the conditions of possible contaninetion. Pased on past data, however, it is not expected that under those conditions of fallout where the radiation levels are below those stipulated for pos- sible evacuation, that the degree of contamination will be a health hazerd. (Nor is it implied here that eny level sbove this does consti-~- tute a serious contamination of water, air, or foodstuffs.) Therefore, it is recoune::ied that no ection te taken in racerd to limiting inteke except to edvis= the washing off of such exposed foods as leafy vegetables : when that action seems desirable, nti ech ft, 2s va
