and flight surgeons of the 56th Zombardnant Wing\¥:).
2.
Geiger-Kuell@ eounters and watts meters were employed, and atroreft
flight patterns were so acrenged as to permit measurements of radioactivity at
various levels between altitudes of 15 fet and 2400 feet over tne Yite.
Enclosure
Ho. I shows the obarted metering results of these tests, indicating ths practiaability of wsing the Trinity Site for subject training.
+he latest estimate of
redioactivity et the Site reveale that an approximate total of 30 ouries remain
