Abstract
An apparatus for measuring radiation exposure in realtime by measuring the charge flowing in an external circuit when radiation creates electron hole pairs, and thus allows discharge, of a duo-dielectric detector.
Claims4
An exposure measuring apparatus comprising:
- a multilayered detector structure, in an electric potential field, said detector comprising a duo-dielectric sandwich including, a transparent conducting layer overlying a transparent insulating layer which overlays a high resistance photoconductor layer which overlays a conductive layer;
- an external circuit connecting said transparent conducting layer and said conducting layer;
- measuring means responsive to the flow of current in said external circuit for measuring the flow of current in said external circuit when said duo-dielectric detector structure is irradiated by radiation capable of forming electron hole pairs in the photoconductive layer of said multilayered detector structure.
