Health effect 1976739 185999774 2008-01-22T00:13:01Z WhatamIdoing 1998764 /* See also */ '''Health effects''', '''health impacts''' or '''health risks''' are changes in [[health]] resulting from exposure to a source. Health effects are an important consideration in many areas, such as [[hygiene]], [[pollution]] studies, [[workplace safety]], [[nutrition]] and [[health sciences]] in general. Some of the major environmental sources of health effects are [[air pollution]], [[water pollution]], [[soil contamination]], [[noise pollution]] and [[over-illumination]]. A non-[[stochastic]] or deterministic health effect has a severity that is dependent on dose and is believed to have a threshold level for which no effect is seen. Stochastic health effects occur by chance, generally occurring without a threshold level of dose, whose [[probability]] is proportional to the dose and whose severity is independent of the dose, such as [[cancer]] and genetic effects. ==See also== * [[Material safety data sheet]] * [[Risk factor]] * [[Health effector]] ==Sources== *[http://www.nrc.gov/reading-rm/basic-ref/glossary/full-text.html Nuclear Regulatory Commission - Glossary] [[Category:Health effectors|Effect]] [[Category:Pollution]] {{health-stub}}
