Project 21.3 - Short Half-life Activities - PF. Momyer
Another phase of Project 21.3 was engaged in findirg total tritium in
the cloud,
This was done in the following manner:
Carrier amounts of heavy
water, krypton anid xenon vere adie! to the collection bottles prior to the
progran,
The collection system corsiste! of filters “or particulate matter
am collection bottles mounte? on the sampling planes,
Gas samples vere
collecte? at varicus altitudes ar! times following the detonation and returned
to Parry for separation.
Krypton, xenon, water and carbon dioxide vere
separated from the gas sample and molybdenur was separated from the filter
sample,
Krypton, xenon and molybdenum were collected to “etermire fissiona
per collection bottle,
The remaining activities, cl4 and fl vere returned
to the laboratory, as barium oarhonate and water for the determination of
total tritium and possibly cl yield.

The fission bottle data are shown in Table 2]. 3-1.
