a considerably narrower area than we set
our sampling stations out, end we plot here
the disintegrations per minute per square
foot against distance from the site.
The fallout is pretty good with
the end occurring at something like six or
seven hundred feet anda plot of the pre-e
dicted, that is using the theory or the
various theories of diffusion, a plot of the
predicted fallout falls almost identically
on this line.
It's really a very good fit and so
we were very happy with this,
We went out and did another one
and the other one was not quite as happy
as the first,
Ag you can see, the circles on
this. plot-- oh, by the way, this was done
around 360 degrees,
Wa weren't very happy
with the wind direction, eo that we actually
set our samplers up on annuli out on two
thousand feet, that is twentyefive, fifty,
seventy-five, one hundred, two hundred and
so forth on sixteen points around the compass
of the two thousand feet.
And, as you can
see the results got down to a point and then
just seemed to stay there,
They looked very curious when we
