Abstract:

Electric ignition elements Mk 2. Mk 4, and Mk 6 have been exposed to gamma radiation from a cobalt-60 source. Dosages ranged from 1.75 X iO5 to 78.23 x 10exp6 roentgens. The effect of this irradiation on the sensitivity of the elements in terms of time-to-ignition was variable. The Mk 6 elements showed a general tendency toward decreased sensitivity the Mk 2 elements showed less tendency toward decreased sensitivity and the Mk 4 elements showed an increase in sensitivity.
