https://padlet.com/ihsanrazanicc/rwed8doq5log A monograph entitled Environmental Health Criteria 160 "Ultraviolet Radiation" was published in 1994 by the World Health Organization, jointly in collaboration with the United Nations Environment Programme and the International Commission on Non-Ionizing Radiation Protection. The monograph was the result of an in-depth review of the scientific literature and was primarily concerned with the effects of ultraviolet (UV) radiation exposure on human health and the environment. The penultimate draft was subjected to a WHO Task Group for final peer review prior to publication. Such a review was considered particularly timely in view of the consequences of increasing levels of UV at the surface of the earth resulting from depletion of stratospheric ozone. en-us 2017-04-12 22:05:56 UTC 2023-06-01 13:49:29 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Brightnessdown.png ihsanrazanicc https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166175488 A large body of literature documents the effects
of UV radiation on different living organisms,
including humans, animals and bacteria.
Experimental as well as epidemiological data
strongly indicate that the spectrum of UV
radiation reaching the Earth’s surface is involved
in the development of melanoma (IARC, 1992).
The biological effects of exposure to UV
radiation were described in detail in an IARC
Monograph on UV radiation (IARC, 1992), and
the molecular effects in recent review articles
(Griffiths et al., 1998; Pfeifer et al., 2005). In this
section, we summarize the aspects most relevant
to the understanding of the biological issues
associated with exposure to artificial sources of
UV radiation.]]> 2017-04-12 22:06:34 UTC https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166175488 ihsanrazanicc https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176520 Prolonged human exposure to solar UV radiation may result in acute and chronic health effects on the skin, eye and immune system. Sunburn (erythema) is the best-known acute effect of excessive UV radiation exposure. Over the longer term, UV radiation induces degenerative changes in cells of the skin, fibrous tissue and blood vessels leading to premature skin aging, photodermatoses and actinic keratoses. Another long-term effect is an inflammatory reaction of the eye. In the most serious cases, skin cancer and cataracts can occur.]]> 2017-04-12 22:25:40 UTC https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176520 ihsanrazanicc https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176794 2017-04-12 22:31:35 UTC https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176794 ihsanrazanicc https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176975 2017-04-12 22:36:17 UTC https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166176975 ihsanrazanicc https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166177112 2017-04-12 22:39:06 UTC https://padlet.com/ihsanrazanicc/rwed8doq5log/wish/166177112
