not require power or time algnals for the operation of the

You will not have any requirements for labor crews.
In addition to the above, I want to bring you up to date an
the latest plang of the test organization, and to ascertain
what effect these changes may have on your operations.
On September 29, the subcommittee (consisting of George Lercy,
U, Andrews, ani Lt. Comir. Cronekite) of the Bio. Med. Test
Screening Gomaittes met here in Washingtan to consider in detail
the proposed Biological experiments. 4t this same wating,
Bob Corsbie outlined the plans for the shelter test, etc.
Present planning seema to indicate that it would be deairahie
to test the shelter in Tucca Flat. completely indepemient of
the Military Effects Progras. It would probably be subjected

Dr. Leroy pointed ont that the neutren levels we quote are
based on Cdegold and sulpher measurements. The Gdegold technique
does not measure much above .2 ev, and the sulpher technique does
not measure anything below 3 MEV. Therefore, there ia a gap
between 2 ev. and 3 MEV that is not being measured, There is
avidence from the Greenhouse work to indicate that there is
bielogical damage which is believed to be from the neutron in
the range. ide have requested that copies of the Greenhouse
report and the Shelter Test report bs sent to you, and they
abould be there within the next few days.
