It was suggested in Felicy Ii that normal clozed-type footwear (aa compared to much as open sandals) would crobubly afford adequate proteetion against significant beta doses to the feet fro: fallout zaterial on the ground. There fe still the added problem if the »aterial be seuffed up and sling to the ankles and lower legs. If thera vere no intervening clothing, or perhaps even with thin stockings or socks, this might result in significant dlological beta deses being delivered to these parts. Por example, if the gauza dose rate reading at #43 hours were something less than tax ‘roentgens per hour, svacuation would not be indicated, Nowever, for fallout material of the same concentration in eontact with the skin the beta dose rate at 7 mg/e:* would be about 600 reps/nour. (See Appendix B.) Presurably, per sonnel would be kept indoors for a few hours but upon release the approximate beta dose rates at 7 wg/ex:* would be 26 aor three hours later or 210 ‘masa six hours later. tration oft In addition, there is the variable factor of what concen= Pwetertal nay accumulate in the ankle region bywalking around aD area, 4 concentration of fallout material on the ground that would result ir shout 29 roentzgens caxinus theoretical infinity ganea dose, if in econtact with the skin would result in e beta dose rate to the basal layer of the skin of about 1/4 spSQM thoce indicated in the previous paragraph.
