Airblast measurements were made at three locations ranging from about 3000 to 20,000 ft. from each of the four shots of ESSEX I, Phase 2, as a part of a continuing effort to record the effects of charge burial depth and emplacement configuration on the suppression of airblast, and to further evaluate the use of airblast suppression as an analog of suppression of radioactive fallout. Suppression of airblast impulse in the gas venting pulse for the four emplacement configurations was consistent with that for earlier shots when differences in emplacement configuration are taken into account. Impulse suppression in the gas venting pulse appears better than energy suppression as an analog of suppression of radioactivity. Where the suppression of radioactivity has been simulated with a tracer, the suppression factors are equal to or less than those determined from airblast impulse. Possible reasons for the differences are discussed. |
