A multi-disciplinary research project on water disinfection using UV radiation was carried out under laboratory conditions as well as in selected pools and waterworks. The influence of UV radiation on physical, chemical and microbiological properties of water was determined. The report describes prototype devices and disinfection systems, as well as methods of determining UV radiation dose and α absorption coefficient.

Comparative studies of the structural, electrophysical properties and spectral sensitivity of 4H-SiC photodetectors of ultraviolet radiation in the spectral range of 200-400 nm were carried out before and after electron irradiations. Photodetectors with Cr Schottky barriers with thickness of 20 nm and 8 mm diameter were formed on n-4H-SiC CVD epitaxial layers with a thickness of 5 μm and concentration Nd-Na= (1-4) х1014 cm-3. Cr/4H-SiC photodiodes were irradiated by electrons at 0.9 MeV energy with doses (0.2-1) x1016 cm-2.
