Project 2.2 -— Gamma Rate versus Time
Agency:
Signal Corps Engineering Laboratories (SCEL)
Operations:
Scintillation detectors were used to measure initial and
residual gamma rates as a function of time and distance.
The finstru-
ment stations were self-contained and required only timing signals to
turn them on at predetermined times.
Instrumentation was instmlled on
14 islands along the northern, southern, and southwestern perimeters
of Bikini Atoll and on Bokoluo at Enewetak.
Shots:
BRAVO, ROMEO, KOON, UNION (Bikini); NECTAR (Enewetak).

Staffing:
High during instrument recovery,
Two civilians associated with this project, both frm SCEL,
received 4.040 and 6.280 R.

Project 2.3 -- Neutron Flux Measurements
Agencies:
Naval Research Laboratory (NRL)
Oak Ridge National Laboratory (ORNL)
Headquarters, Military District of Washington
Operations:
Neutron flux was measured by installing fission dktectors
at sites on islands in northern Bikini Atoll, although only t
tions on Bokbata and the reef were used.
