Milisiverts per year exposure
Ionizing radiation has deterministic and stochastic effects on human health. Deterministic (acute tissue effect) events happen with certainty, with the resulting health conditions occurring in every individual who received the same high dose. Stochastic (cancer induction and genetic) events are inherently random, with most individuals in a group failing to ever exhibit any causal ne… WebWe use microSievert per hour (μSv/h) for hourly exposure and milliSievert per year (mSv/y) for annual exposure.
