Document Summary
Female reproductive system response: follicle sensitivity varies with stage, age, and position in the menstrual cycle. Primary follicle: small - most resistant: most dormant, primary follicle is resting stage - not actively dividing. Secondary follicle: intermediate - most sensitive: change in size and shape - huge increase in growth, active division occurs in secondary. What happens with large single doses not usually intentional. A relationship of specific signs and symptoms to specific type of trauma or disease process: ars is a combined response of multiple body systems, requirements. Total body irradiation over period of minutes. External penetrating radiation source (not internal to the body: not large dose from brachytherapy. Survival time: primary effect is shortened life span (early radiation lethality) Survival time and mode of death depend on dose. For given dose, survival time for person varies according to the individual. Ld50/60 - lethal dose (1st # = % of population will die, 2nd # = how many days: approx.
