Radiochemistry Division measured all nuclear tests conducted
by LRL.
Under the Plowshare Program, the division investigated
the production of transcurium elements from nulcear explosions.
Other radiochemists worked on high-altitude diagnostic systems
as part of atmospheric testing, including participation in PPG
field test preparations, obtaining radioactive debris and gas
samples from the atmosphere, using an airborne radar system to
detect and delineate nuclear clouds.
Earth Sciences
Earth Science Group made extensive measurements of the underground experiments of Hardtack II, mapping Rainier, Blanca,
Logan, and Neptune events to determine radiation and temperature
distribution, thermal energy, and various geological phenomena.
From the data developed at Gnome, Earth Science devised a temperature and radiation system. [See LRL-Nevada. ]
Photographic
Group
The Technical Film Group provided photographic services,
using in-plant camera, lighting equipment, sound-recording systems, time lapse and time-motion photography.
The Photography
Group also was assigned to Plowboy, and produced two Plowshare
films ("Industrial Applications of Nuclear Explosions-- Mining";
"Creating Experiemnts with Chemical Explosives").
The Photography Group provided documentary and scientific
film processes
and safety movie coverage
for all
LRL experiments
at NTS and high-speed photographic studies of tests, including
Miniature blast models.
The group also used a radiocontrolled
system of remote photography of nuclear events.
