made by the Staff Surgeon and certain rough calculations accomplished
on the basis of these assumptions and consultetion with JIF-7 scientifieand technical personnel.
1.
In general, these assumptions were:
That the 19,000 count per minute quoted referred to counts
per cubic meter of air.
2.
That the counter efficiency was:
(a) 50%
(b) 20%
On this basis, it was concluded from the calculations that all re-
sults were within permissible limits for emergency and continuous consumption for air and water as recommended by the National Committee for
Radiation Protection and Measurement (NCRP) and elso by the International Commission on Radiation Protection.
~~
Commander JTF-7 and the
Deputy for Scientific Matters were advised to this effect by the Staff
Surgeon.
No further action was taken at this time.
