The constant expansion of the spheres of application of artificial radiation sources in everyday life once again shows the importance of light sources in our life. Radiation sources (RS) are used in such spheres as lighting, film projection technology, control of various photochemical and photobiological processes, photo etching and photolithography, creation of electronic components. In recent decades, pulsed RSs of the continuous spectrum, used in film projection technology, photography, medical technology [1,2], laser pumping, etc., have been widely used. A fairly wide range of metrological equipment and techniques has been developed for recording the radiation from continuous combustion RSs. For example, successfully applied photophysical methods based on the internal or external photoelectric effect, and photochemical recording of radiation based on changes in the optical or physical properties of a substance under the influence of light are well-known [3]. The above methods make it possible to obtain reliable results when recording sources of continuous combustion, in particular, linear or monochrome emission spectra. However, recording the RSs of the pulsed continuous spectrum causes difficulties and leads to significant errors. The need to determine the quantum yield of the reaction as a function of the spectral composition of the radiation, the requirements for the thermal stability of the material used, the impossibility of using the substance repeatedly, and the practical inapplicability of existing actinometers to detect shortwave ultraviolet (UV) radiation in the range 200–240 ИЗМЕРЕНИЕ СПЕКТРАЛЬНОЭНЕРГЕТИЧЕСКИХ ХАРАКТЕРИСТИК ИМПУЛЬСНЫХ ИСТОЧНИКОВ ИЗЛУЧЕНИЯ СПЛОШНОГО СПЕКТРА
