Simple solid-electrolyte gamma-ray and relativistic-charged particle dosimeter

Abstract

Abstract A gamma-ray and relativistic charge particle detector and method for measuring the amount of radiation passed through the detector. The detector is a dosimeter comprising a plurality of equally spaced batteries disposed to form a series of columns and rows within a plane having vertical and horizontal rectangular coordinate axes. The batteries, radiation sensors, can be repeatedly charged and discharged with very little characteristic change in the discharge curve. The batteries have a solid electrolyte and a low voltage output. Radiation passing through the electrolyte causes partial ionization of the electrolyte, which reduces the battery terminal voltage in proportion to the amount and type of radiation passed therethrough. Before and after being exposed to radiation, the batteries are placed in a test stand and the individual battery voltages are simultaneously measured and recorded. A change in voltage across the battery terminals, after exposure to a known type of radiation, is proportional to the radiation passed therethrough. Thus, differential voltage, displayed as a contour map or picture of the radiation pulse, is representative of the radiation intensity passing through the detector.
