ULTRAVIOLET RADIATION. INTRODUCTION. This chapter may serve as a guide to industrial hygienists who are responsible for evaluating and making recommendations for the protection of workers from potential health effects of ultra- violet radiation. The guidelines and the exposure limits are based on available
UV photochemical injury to the cornea (photokeratitis) and lens (cataract) of the eye (180 to 400 nm). In deriving the exposure limits (ELs), the underlying assumptions were (a) that exposures could be averaged over a 1-mm aperture at the corneal plane for pulsed exposures lasting less than approximately 0.3 s, whereas,

The shortwave UV radiation (UV-C) poses the maximum risk. The sun emits UV-C but it is absorbed in the ozone layer of the atmosphere before reaching the earth. Therefore, UV-C from the sun does not affect people. Some man-made UV sources also emit UV-C. However, the regulations concerning such sources restrict
For determining exposures to X- or gamma rays up to 3 Mev., the dose limits specified in this section may be assumed to be equivalent to the "air dose". For the purpose of this section air dose means that the dose is measured by a properly calibrated appropriate instrument in air at or near the body surface in the region of
It includes ultraviolet (UV) radiation, visible light, infrared .. guidelines). ? Minimize dose (low-dose protocols). The radiation exposure from a single diagnostic procedure is usually small. However, many people undergo .. Consequently, human beings and the environment are exposed to higher UV radiation levels, and.
helps Americans plan outdoor activities to avoid overexposure to UV radiation and thereby lower their risk of adverse health effects. UV radia- tion exposure is a risk factor for skin new reporting guidelines for solar ultraviolet radiation. EPA recommends that you use some of the messages identified in the chart below.
5 Feb 2004 INTRODUCTION. SINCE THE publication of the ICNIRP Guidelines on UV. Radiation Limits (ICNIRP 1996),† recent research has made it appropriate to update the guidelines for protec- tion. While no significant changes are made in the values, the biological basis can be strengthened, and the limita-.

You had a specific question about workplace exposure limits for ultraviolet radiation. We have responded to your paraphrased
the International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides scientific advice and guidance on the health and environmental effects of non-ionizing radiation (NIR) to protect people and the environment from detrimental NIR exposure. NIR refers to electromagnetic radiation such as ultraviolet,
