Document Summary
Radiographs can reveal asymptomatic conditions or contin/contradict clinical observations. Radiation can cause unwanted changes in living cells. Radiation can create damage for generations to come. Compton/photoelectric effect leads to further conization formation of ion and disloged electron biological depends on sensitivity of cells/issues involved. Conization of water molecules from padiation yellds free radicals can combine wl other molecules to seek stability and toxins can result. Stochastic vs non-stochastic effects of effects or lonizing radiation exposure. Chance of effect is direct function of close. No close threshold low or arg exposure. Non stochastic: occure due to conization effects on chromosomes/genetic mutation. Have a threshold occur due to major cell damage/cell death strong exposure. Sequence of radiation injury latent period -period of. Short terms high dose in short time, extensive cell death, tosuel organ damage, cataracts asterility burns. Long term: repeated low closes, no immediate problem to any body organ, effects occur at cell level.
