Abstract

MEASUREMENTS of the conductivity induced in insulating materials by X- and γ-rays have shown the existence of a long period decay1, and more recent investigations2–4 have shown that the electron-trapping mechanisms which apply to photoconductivity also apply to these materials. This general picture may enable the energy-level distribution of the material to be elucidated. The present experiments have been concerned with polythene and “Perspex”, and have used a d.c. amplifier to measure the current induced by X-rays of 220 kV_P_ (half-valuelayer = 2.5 mm. copper) both during and after irradiation.
