View source for 119. Health effects of ionizing and non-ionizing radiations

* Basics of radiation
** Alpha radiation consists of helium nuclei
** Beta radiation consists of electrons
** Gamma radiation consists of photons (electromagnetic radiation)
* Units related to radiation
** Gray (Gy) = absorbed dose
** Sievert (Sv) = equivalent/effective dose
* Ionizing radiation
** Mostly gamma rays
** Alpha and beta radiation has low penetrating power and therefore only causes disease if inhaled
*** Radon can be inhaled, and it gives alpha radiation
** Natural sources of ionizing radiation
*** Radioactive disintegration (mainly from uranium)
*** Cosmic radiation
*** Radioactive potassium
*** Radon occurs naturally in soil
** Occupations with high ionizing radiation exposure
*** Jobs in nuclear medicine
*** Miners
*** Pilots
*** Gas and oil industry
** Health effects of ionizing radiation
*** Deterministic effects
**** Vomiting
**** Skin burns
*** Stochastic effects
**** Cancer
* Non-ionizing radiation
** Ultraviolet
*** UVA
**** Least energy
**** Mostly related to premature aging
**** Less related to cancer
*** UVB
**** Mostly related to sunburns
**** Highly related to cancer
*** UVC
**** Highest energy
**** 99% is absorbed by the ozone layer, preventing UVC from reaching us
*** Occupations with UV exposure
**** Outdoor workers
*** Health effects
**** Erythema
**** Premature ageing
**** Skin cancer
**** Outdoor workers have the highest UV exposure
** Infrared
*** Occupations with IR radiation exposure
**** Bakers
**** Glass blowers
**** Blacksmiths
*** Health effects
**** Corneal and conjunctival burns
**** Retinal injury
**** Cataract
** Laser
*** Skin problems
*** Eye problems
