This is a mass rating rather than a redioactive rating?
RAPPs
Yes, this is « sass rating,
This is just a percentage
of the initial saterial.
“i
I would like to say that we find the distribution rate 1

inverse with the time to the first power.
That is, the
effactive rate of decay of this thing is 2 minus 2.2

there is some scattering data which would show you the e

Is it the center?
VOICEs
Tt is the hottest part.
Ke try to find a place where

is the least diffusion.
For example, an isokinetic stre

line which happens to be running through the center of
cloud.
If we can find an isokinetic layer this is where.
we fly, because this is where we get the nost mterial.

That diffusion rate ia for a very yound cloud in the firs,
half an hour isn’t it?
PLANEs
Fell, we usually started in at one hour and cell it a day
after about S hours.
APP,
Bell, let me say that this sodel is set up and is highly
idealized.
We believed that the cloud would not be con-
tinuous and expanding like this we are siaply trying to
see what guch a mode] would bring down in the way of rain
outs.
