Abstract

The paper describes the experimental setup is designed to study the intensity of radiation in the optical range of different transparent media when exposed to ionizing radiation of different nature. Calibration of the setup was carried out using the standard light source with dense filters. Particular care in the measurements was given to the background light sources induced by ionizing radiation. A study of the luminous flux, which occurs under the action of gamma rays, beta particles, alpha particles and gamma-neutron field was carried out with air, water, organic glass and quartz. The measurements were made by a relative method. As a reference was used stilbene crystal. It was shown that luminosity of media may register even for relatively small values of the dose rate of gamma radiation. Air glow induced by alpha and beta particles, greatly intensified than gamma-quanta. Comparative analysis of the luminous fluxes emerging in different media can be concluded that the responsible for the appearance of a number of different processes occurring in the medium during braking of charged particles. Among them, the largest contribution comes from the Cherenkov radiation, phosphorescence and luminescence of the media. The obtained results allow to develop a device capable of remotely assess the dose field and at the same time over a wide area. Such devices can be claimed for various technological operations carried out with high activity sources and to assess the dose field arising after a severe accident at nuclear facilities.
