Assessment of the danger of using ultraviolet lamps in electrical systems. Przegląd Elektrotechniczny. 2024. № 2. P. 152–155. DOI: https://doi.org/10.15199/48.2024.02.310033-2097https://dspace.pdau.edu.ua/handle/123456789/16820To determine the photobiological safety of UV lamps, the following measurements were carried out: spectral irradiance, total actinic irradiance in the wavelength range of 200-400 nm, and irradiance in the UVA range (320-400 nm). These parameters were measured using the optical radiation system OST-300. The photobiological safety of LUF 40-1, LE 15 lamps and their radiation risk group are established in accordance with EN 62471. The levels of UV radiation generated by LE 15 low pressure discharge lamps at a distance of 0.25 m belong to the high risk group (GR3), and LUF 40-1 - in the group of insignificant risk (GR1). Calculations and recommendations on safe radiation doses when using lamps in electrotechnical systems of photobiological influence are given.enPhotobiological safetyUV irradiancecarcinogenic safety of radiationspectral intensityArticle
