Activity Concentrations in Air
The highest measured concentration of fallout activity in the air of
populated areas was at Saint George, Utah on May 19, 1953, amounting to
1.29 microcuries per cubic meter averaged over 24 hours.
A calculation
of the possible lung doses from this fallout indicates a value probably
greater than 115 mrems and less than 230 mrems.
This is less than the
dose to the lungs each month from naturally occurring radioactive substances in the air, contained in Appendix V. A.
An inspection of the other
data in concentrations in air shows that this single lung dose is also
higher than the accumulated lung doses from multiple fallouts in other
populated areas for all tests.
Buster—-Jangle (Fall 1951)
Tne highest measured concentration of fallout debris in air was at
Ely, Nevada amounting ts 0.202 microcuries per cubic meter averaged over
24, hours,
#11 othsr measurements were in order of magnitude lower (Data
taken from Wi-425 Padislogical Safety).
