Opis:: The article discusses criteria for the assessment of exposure to visible radiation (blue light), methods of measurement of radiation exposure and hazards during welding. Then, the author presents the results of measurements of exposure to visible radiation in the electrical and gas welding. Based on the results of these measurements the occupational risk for the studied positions has been determined.

Opis:: The article presents a method of evaluating irradiance, spectral irradiance, and spectral radiance, for purposes of determining risk groups of sources of light. The description of the method of measurement of radiance incorporates standard and alternative methods. Measurement methods were developed on the basis of general requirements and diagrams incorporated in the standard PN-EN 62471: 2010. The paper classifies risk groups of sources of light in terms of photobiological hazards and exposure limits when skin is at risk of being damaged by visible and infrared radiation. Threshold values of emissions for the continuous sources of radiation studied are presented. The article describes environmental conditions under which the measurements are to be taken, and requirements applicable to the process of light source aging. In addition, technical assumptions are presented, and the design of the test stand for measuring optical radiation parameters is described.

Opis:: The article, based on the records of the EN 62471:2008, presents guidelines for photobiological safety of lamps and lamp systems. There are allowed safe exposure times presented and emission limit values for each of four risk groups, defined by the standard. The paper presents criteria for lamps irradiance or radiance measurement. Discussed risks with association of ultraviolet, visible and infrared radiation. For a detailed presentation of the potential risks associated with the blue light, there is made a comparison of spectra of selected light sources. On these basis, the blue light hazard assessment was presented for selected light sources.

Opis:: Objectives: Nowadays more and more newly introduced light sources (tungsten-halogen, compact fluorescent (CFL) and light-emitting diode (LED) lamps) are used in households. It is important to know whether their radiation poses any possible risk for human health or not. These light sources emit optical radiation not solely in the visible spectrum. Other bands emitted by these sources, i.e., ultraviolet and infrared, are potentially hazardous for human health. The visible light, especially the blue light, could also damage human retina. The purpose of this study was to determine the ultraviolet (UV) and blue light (BL) emissions from halogen bulbs, CFLs and LED lamps, and to evaluate them from the point of view of possible health risks for general public. Material and Methods: The exposure of UV and BL emissions from 19 types of CFLs, 11 types of halogen lamps and 4 types of LED lamps produced by different manufacturers were measured at 200 mm distance from the source. Results: The exposures to UV and BL were below the International Commission on Non-Ionizing Radiation Protection (ICNIRP) exposure limits in spite of the very conservative assumption of the assessment. Conclusions: Results of this study indicate that the UV and BL radiation from the newly introduced lamps does not exceed the current exposure limit values and thus, in comparison with the former incandescent bulbs, does not result in a higher risk for general public.
