WebThese are called deterministic effects and the severity of the effects varies according to the radiation dose received. They can include acute radiation syndrome, skin burns, loss of hair, and in extreme cases, death. Most deterministic effects occur shortly after exposure and above dose thresholds specific to each exposed tissue.

Of those, 28 workers died in the first three months. WebThe deleterious effect ionizing radiation has on human tissue can be divided into two types: non-stochastic (deterministic) or stochastic effects. Deterministic (Non-Stochastic) Effects Deterministic effects only occur once a threshold of exposure has been exceeded.
