IV - BIOLOGY AND MEDICINE r Weapons Test Activities (BUSTER - JANGLE) Project. Gabriel. Project Gabriel was ‘an evaluation of long-range hazards associated with the detonations of a large number offatomic air bursts.

Monitoring at Test Site (BUSTER-JANGLE). Persormel test site area were issued film badges by the RadSafe Unit. personnel radiation report requires some upward revision off exposures previously reported. This report shows that of the 1,749 persons with badges none exceeded an integrated dose of 6 roentgens, an only 12 exceeded 4 roentgens. These 12 represent less than 0.7 percdnt of the total personnei subject to exposure. 1.2 roentgens. { The average integrated expdsure Was about The timing of each shot with respect to Weather con itions was the major factor in preventing significent fall-out in pop lated areas. However, surveys of fall-out in the test area were made-b helicopter and estimated results show “hot" areas with integrated doses 75 roentgens at 15 miles from the surface shot, and 175 roentgens at 9 iles from the underground shot. Since these specific areas Were observ within the Nevada Test Site, they do not represent.a health problem fo populated areas. However, such fall-out patterns are phenomena notffully understood or predictable. Further monitoring should provide q@ata upon which to base predictions of fall-out patterns for future tests Monitoring of air activity.
