It was suggested in Policy II that normal closed—type footwear (as @ompared to such as open sandals) would probebly afford adequate protection against significant beta doses to the feet from fallovt material on the ground. ) There is still the added problem if the material be scuffed up and eling to the ankles and lover legs. If there vere mo intervening clothing, or perhaps even with thin stookings or socks, this might result in significant biological beta doses being delivered to these parts. For example, if the gamma dose rate reading et B43 hours were something less than ‘fam roentgens ( per hour, evacuation would not be indicated Rovever, for fallout material of the same concentration in eontact with the skin the beta dose rate at — 7 ne/ex* would be abort 6% reps/hour. ‘See Appendix B.) Presumably, pere sonnel would be kert indoors for a few hours bit ucon release the approxinate beta dose rates at ” mgem wuld be 260 ww//br three bours lster or 210 at/or six hours later. In addition, there is the variable factor of what concen- tration ofMinatertel may aocuculate in the ankle region by walking sround an area. A concentration of fallout material on the ground thet would result in about 20 roentzgens mario theoretica. infinity gaura dose, if in ¢antact with the skin would result in a beta dose cate to the basal layer of the skin of about 1/, SEE those indicated tn tne previous paragraph.
