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.

In addition, there is the variable factor of what concen=

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.
