10% of radiation induced damage is irreparable
True
False
What is the first step in the protection of reproductive organs?

True
False
ARS is what type of effect?
Early stochastic
Early somatic
Late non-stochastic
Late stochastic
Late somatic effects result from:
(Select all that are true)
Previous whole or partial body acute exposure
Previous high radiation doses
Low-level doses sustained over years
Late effects are the greatest concern when regarding what type of radiation?
Low-Level
High-Level
Non-ionizing
All ionizing
Select all that are types of late non-stochastic/tissue reactions
Cancer
Birth defects
Cataracts
Nausea, vomiting
What types of effects are presumed to follow the non-linear threshold dose response curve?
Hematologic depression
Skin Erythema
Cataracts
Genetic damage
Most types of cancer
Stochastic means that biological effect increases in severity as the dose increases
True
