Problea of sanpling in the atsosphera is a very diffi
One. ‘If we find that there is worldwide dissezination
of fission products and particularly strontiva, it s

to ae that 1t is extrenely likely that this waterial is
transported above the weather layar in what you call the
stratosghere.

So we have to sazple it.

#e have to te

how much is up thore or we have to prove that it is up
there.

%e hava various ways of sarspling this, { think

simplest thing 1@ to take soue rainwater saaples fros
various parts of the earth's surface several aonths afte:
any bozb has been shot.

It seeas very likely and reason

able to ae that aiy flasion products of strontius that

get velow 30,000 feet where your rain ig scavenging the
air all the tise will have been washed out rather quick

if you can go te Southern Chile next Thanksciving and

a bucket of rain and find strontiws coming out of the
heavens, I think it's very good evidence tiat you have
strontium in the highest layers of the stratosphere and
stratospheric transport.

Put, regardless of what the

{mplications are, if you find strontium coaing out in
rain six months after any borb is shot this is an impo
fact in itself.

So thare's no doubt that we need to coliket

rain sauples and to geasure them.

fe need the ccean sacpies.

because this is the next best eedius.

How shall we meas

the ocean, what shall we do about it?

tell, strontiue is
