This system was developed primarily
for the weapons test and it soon became fairly
obvious that this was not an ideal system or
technique for the Civil Defense work because
they would heave to go out and take a look at
the large areas of fallout to determine what
measures had to be taken for emergency, what
supplies had to be brought in.
Our first accociation with that
problem was operation alert,
last June,
where we undertook to send information froma
New York to Boston, ©
What we did was, we
took the fallout pattern which was described
for New York and we reproduced this pattern
on regular recording tave, using the type
of elignal letters put out by our information
etation.
Then, when Operation Alert came
we put this information right into a telephone
line and sent it up to Boston.
In Bocton we have thie central
station (indicating) and what we did was to
take the data as it ceme over and plotted
the iso intensity lines that had been laid
down for the New York area..
I don't know whether you can see
this, but I'11 give you an idea of what it
looks like.
I am going to give you this
