Now, for a reasonably sized build-
ing, say, a& building of this one in height,
it is 10 feet ~ the cellar depth is 10 feet,
and it has a radius of 60 feet, one can see
in terms of the total dose rate experienced
by an occupant of this cellar,he is receiy-
ing something on the order of 50 per cent,
50 per cent of his total dose from the scatter,
It 4s a matter of some importance
obviously, to determine what increments in
dose rate are contributed by annujie surrounding a person ag you clear areas around his
end this exhibits the material for the scatter
and primer data = for the matter and total
data, the effect of clearing.
If by some mecheniem, one could com
pletely olear the area 100 feet around a per |
son with no other attenuating mechanism, no

concrete, no cylinder or anything else, one

would have reduced the infinite plane dose
rate by a factor of more than three and as,
you go out to 500 feet it's down to the order
of 10 per cent.

Doe you mean that it
