THE TsST PROGRAMS (3)
—
The status of tne Ivy experimental projects as of ‘the end of June
including revisions to tue experiments brought about by knowledge gained
during the Tumbler-Snapper Operation is given below:
PROGRAM 1
RADIOCHEMISTRY
The final specifications of the internal radiochemical detectors
to be used by Project 1.2 have been fixed.
In general, these detectors
are the same as those mentioned in previous installments but vary in
dimensions and location.
Dr. Harold Plank of Project 1.3 is making arrangements for com=
paratively simple back-ups on the air sampling for Mike Shot.
He plans
to arrange containers which will allow for the collection of radioactive
water after the shot if there is difficulty with the airplane sampling.
This water sampling would not be by remote control.
He also plans to
arrange for two bloweretype air samplers, one to be on Bogallua, the other
to be on Engebi.
The details of tnese collectors are not yet available.
