comparisons with CROSSROADS Baker are made. It is
estimated that between 100,000 and 130,000ttons of water
in the Baker column contributed to the surge,
that the
column height was between 3500 and 4000 feet, and that
the column density was between 1.4 and 1.6 times that of
801.

A thin polyethylene chamber ionization detector
has shown remarkable beta flux sensitivity. It was found
that by adding a removable beta flux discriminator to
the chamber it was practicable to differentiate between
the beta component and the gamma component of the flux
coming from a contaminated field. Laboratory experiments
and field data substantiate the practicability of the
system described. The gamma energy dependence of the
detector was found to be a maximum of 17% high relative
801.

950. ABSTRACT
Samples of soils from Trinity and Eniwetok,
thermally alitered as a result of the test Shots of 1945
and 1948, were examined. At Trinity a crust of
vescicular silicate glass covers the ground over an area
of about 2000 feet diameter. The amount of glass formed
is estimated as 17 x 10{sup 8} grams. Petrographic
evidence indicated that temperatures exceeding 1470{sup
Q0}C were reached throughout this area. Spectrographic
