Deterministic effects of radiation exposure
WebDeterministic effects are not necessarily more or less serious than stochastic effects. High doses can cause visually dramatic radiation burns and/or rapid fatality through acute radiation syndrome. Acute doses below 250 mGy are unlikely to have any observable effects. Acute doses of about 3 to 5 Gy have a 50% chance of killing a person some ... WebAs the radiation dose increases, the severity of early deterministic somatic effects also. increases.
