effects observed were mild nausea,

burning of the eyes,

and itching of the skin. Later, signs of radiation
injury included epilation and the development of spotty,
superficial, hyperpigmented skin lesions that
desquamated from the center of the lesions outward. All
lesions healed rapidly with no further breakdown of the
skin noted during the observation period. In those
individuals in which hematologic changes were definite,
lymphopenia appeared promptly and persisted for a
prolonged period of time. The most consistent
hematologic change was the depression in the platelet
counts. Urinary excretion of radioisotopes was studied.
From this it was determined that ingestion and
inhalation of isotopes did not contribute significantly
to the initial radiation exposure.

950. ABSTRACT
Pressure-time vs. distance measurements were made
on Mike and King Bursts of Operation Ivy. Mike Burst
offered an opportunity to verify experimentally the
applicability of the W{sup 1/3} scaling law at large
yields; and on King Burst it was possible to observe the
development of the shock waveform over land and over
water. The scaling law was found to be valid for yields
as large as the Mike yield. Overpressures from Mike
Burst are in agreement with the assumption “that the
pressures to be expected from a yield, W, burst at the
surface of a perfect reflector, are the same as would be
observed from a yield of 2W, burst in free air.
Measurements on King Burst showed that the waveform over
water was nearly ideal, whereas that over land was
subject to deterioration as a result of the thermal and
