Document Summary
Radiation and human health: radiation and human health, we can not escape radiation, 1. Background radiation natural radioactivity in the earth and by: 2. Stochastic health effects - chronic: long term, low level of exposure. Increase levels of exposure make these effects more likely to occur but do not influence the type or severity of the effect: affects risk/chance of getting illness, not the severity of it, 2. Non-stochastic health effects - acute: short term, high level of exposure. In 1910, scientists observed that radiation causes skin cancer. Institute, 2014: what are the results of the research done already, three large epidemiological studies have been published since dec. Laboratory studies - no consistent pattern of biological effects is. Increase cancer risk from magnetic field, not for the electric field: workplace exposure (electric utility workers, railway engine seen, 2. Epidemiological studies small risk for leukemia: 3.
