is based on field test data from the JOHNNY BOY shot and further work
by Dr. x. J. Russell.
Dr. Russell concluded that a one-hour dose rate
of one r per hour corresponds to 6.4 microcuries of fractionated I-131
per Square meter and to 18.5 microcuries of unfractionated I-131 per
square meter.
Using a simplified model from the National Academy of
Sciences, National Research Council document on radioactive fallout,
this ground deposition in microcuries per square meter is multiplied
by 32.7 to determine the infant thyroid dose in rads.
The total thyroid
dose can be related back to the gross gamma dose rate.
For one value,
the 1.5 rad child thyroid dose related back to 2.48 mr per hour at
H+] hour.
Using a DASA model, documented in the form of graphs and
nomograms contained in Air Force Technical Manual 136-1,
ties of Atomic Weapons
the Capabili-
(TM 23-200), parameters such as fission to fusion
yield, height of burst, wind,
etc.,
can be applied.
It appears that
the ground deposition prediction compares favorably to the NRDL '"'D"
model.
Capt.
Dieckhoner pointed out that the Air Force is primarily
interested in howt~by-hour prediction and does not place emphasis on the
mr per hour predictions.

COMMENTS ON ROUCHDRAFI OF THE F-106B/AIR 2A NUTEX
In response to the Chairman's desire to express the problems involved
eve
in the F-106 NUTEX, it was suggested that TC/DASA be advised of the
following problem areas which will require further investigation:
