Dear Dr, Warren:
4s I indicated to you in my letter of June 22, 1951, I would keep
you informed of any results obtained at Los Alamos bearing on the
safety of Operation JANGLZ. There is herewith enclosed an informal
report by Dr. Gaelen Felt dealing with this problem and making some
recommendations which are rather startlingly different from those which
were being suggested carlier, Although I am not yet prepared to make
any formel statement from the Los “lamos Scientific Laboratory on this
matter (nor is it clear that I am supposed to do so), nevertheless I
believe that you would be interested in Dr. Felt's approach.
We are endeavoring tos tudy the small particle problem further,
although this scems to present extreme difficulties. However, 1 am
currently of the opinion that the major problem in safety is going to
lie in this fieldrather than in any danger from external radiation
dosage.
We will, of course, continue to keep you informed of any
progress we may make,
Yours truly,
NEB/hgc
