950. ABSTRACT
Eleven samples each of Houston black clay, Caribou
loam, and Decatur silty clay loam were exposed to Able
Burst of Operation Crossroads in order to determine the
effects of the explosion radiation on soil
microorganisms. Microbiological analysis consisted of
making dilutions of 10 g of the samples in steps of 10X
from 10 to 100,000 in sterile water and then using
appropriate dilutions to inoculate certain media to
determine the numbers of microorganisms by the resulting
growth. The total counts of all samples of the Houston
clay were below that of the control
801.
KEYWORD(S)
samples kept
in
Beltsville, Md. In the Caribou loam the actinomcyes and
fungi counts were quite uniform, the protozoa was very
low, nitrite-formers low but definitely higher than in
the Houston clay, and the nitrate-formers were absent.
In the Decatur loam all except four of the fungi and
five of the actinomyces counts were higher than the
controls. All samples except one showed a few protozoa.
All samples contained 1000 or more nitrate bacteria per
gram. The nitrate bacteria were low in all samples.
Since there was no information as to the treatment the
soil samples received at Bikini, it seemed from the
analyses that the microorganisms were not injured to any
appreciable extent.

Unclassified
Hematologic studies were made on swine exposed to
the Test A radiation.
Red blood counts
(RBC)
were
tabulated prior to the test. There was a decline in the
RBC subsequent to the tests; however, the depression was
not as drastic as was observed for the white blood
counts
(WBC).
There were 26 animals that experienced WBC
reductions and of these,
17 died.
The swine which died
had lower minimum RBC than those that lived. The minimum
WBC occurred within 96 hr, and the lowest RBC did not
appear until 16 d to 22 da following the explosion. When
