[en] Efficiency and advantages of chemiluminescent methods for studying radiation-induced defects are discussed, with the reaction between these defects and luminol being as an example. A comparative analysis has been made of the efficiency of excitation of the chemiluminescent reaction in a luminol solution with the following dissolving substances: radiatively-coloured alkali-halide crystals, additively-coloured alkali-halide crystals, various metals and their analgams (K, Na, Ca, Mg, Al). The following efficiency ratios hav been obtained for the above three types of reactions: 1:0.2:(10^-3-10^-5)
