Pulsed radiation response of stressed PVDF shock stress gauges

Reed, R.P.; Greenwoll, J.I.; Bauer, F.; Lee, L.M.; Davies, F.W.; Johnson, D.J.

PVDF shock stress sensors were subjected to X-ray deposition at nominal absorbed levels of 1, 1[1/2], 3, and 5 cal/gm (SiO[sub 2] equiv.) and to neutron fluence above 10[sup 13] n/cm[sup 2] while stressed at a peak level of about 2 GPa. Moderate transitory electrical noise that occurred briefly during the radiation did not persist. PVDF shock sensors with aluminum electrodes appear satisfactory for measurement within these exposure limits. Reference quartz gauges were severely affected.
