The major changes have arisen from health and safety and environmental concerns. These involve chemicals and exposure of personnel to air-borne electromagnetic fields and long wave ultraviolet (UY.A). The changes in the acceptability of certain volatile halogenated hydrocar bons which led to the banning of 1, 1, 1 thichloroethane in 1995 were evident in 1993. The present discussions concerning the emissions of volatile organic compounds (VOCs) in general was also current and has now reached a stage where the effects of these deliberations will become evident over the next few years. Concerns over the exposure of personnel to airborne electromagnetic fields has been current for some years as has discussions to the effects of long wave ultraviolet (UY.A) on human skin. Recommendations as to maximum permit ted exposures over periods of time to both of these phenomena have been put forward and will doubtless form the | | 出版日期 | Book 1993 | | 关键词 | environment; history; material; nondestructive testing; quality | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-1536-0 | | isbn_softcover | 978-0-412-44750-1 | | isbn_ebook | 978-94-011-1536-0 | | copyright | David Lovejoy 1993 |
