The paper gives the results of measuring the characteristics of ultraviolet radiation in UV-C range at consumable electrode mechanized welding in a mixture of shielding gases. These studies were the base for issuing recommendations on protection of welders and auxiliary personnel, as well as personnel not performing welding operations directly. Recorded values of the intensity of radiation, reflected from the welding booth walls (0.03…0.17 W/m2), exceed the TLV of 0.001 W/m2, specified in SN 4557-88. Therefore, when working in a welding booth, it is necessary to take additional measures for protection of the back of the head and neck from exposure to reflected radiation. 8 Ref., 3 Tabl., 1 Fig.
