Deterministic radiation effect
Effect of ionizing radiation leading to a functional
loss of the irradiated organ or tissue, if sufficient cells are killed
or prevented from reproducing or functioning due to radiation. The seriousness
of this loss of organ function is directly proportional to the number
of cells affected. Since the function of many organs and tissue is not
impaired by a limited reduction in the number of functional cells, a
threshold dose for deterministic radiation effects exists, which must
be exceeded for an effect to occur. In the case of radiation doses above
this threshold the degree of pathological severity increases rapidly.
The deterministic effects of ionizing radiation include skin reddening
(dose threshold 3 to 5 gray), opacity of the eye lens (dose threshold
2 to 10 gray) and permanent sterility (dose threshold 2.5 to 6 gray).
