Abstract
Abstract It has been shown that it is possible to measure radiation doses using the chemiluminescence (CL or lyoluminescence) of different solids. The purpose of this study was to find out whether chemiluminescence from drugs, as well as from other solid materials collected in the neighbourhood of a radiation accident, could be used to estimate the radiation dose to the people involved in the radiation accident. CL glow curves of 18 gamma ray irradiated powdered drugs were investigated. For seven selected pharmaceuticals, optimisation of the CL yield according to sample mass, pH of solution and concentration of luminol was performed. We found that with many powdered drugs, doses as low as about 1 Gy can be measured. The CL of 10 irradiated solid materials (hair, finger-nail clippings, chalk, cellulose, etc.) was investigated using luminol solutions. The results showed that it would be very difficult to observe a radiation induced chemiluminescence with doses of about 1 Gy, when using solid materials of minimum solubility in the luminol sensitiser system.
