[Ultraviolet exposure in the environment of welding work sites].

It has been checked if the "limits of the acceptable doses of ultraviolet radiation of monochromatic radiation at the workplace" (NIOSH-standard of USA) are adhered to in the vicinity of welders' work stations in a factory hall. For recording of UV-doses polysulphon films have been used. According to these investigations non-welders are exposed to doses of UV-radiation which exceed the limits recommended by about eight times. Clinical examinations of these persons showed chronic damage of the external parts of the eyes in a higher percentage than in a control group. It is pointed to the necessity of taking protective measures to shield persons working in the vicinity of welding job sites from ultraviolet radiation.
