Radiation Syndrome(ARS, radiation sickness) early somatic tissue reactions, occurring in humans soon after whole body reception of large doses of ionizing radiation delivered over a short period
curve (DR curve) goal is to establish relationships between radiation and dose response.
threshold (LT)- biologic response does not occur below this dose
Syndrome aka bone marrow syndrome- occurs when people receive whole-body doses of ionizing radiation from 1-10 Gray. Causes the number of RBC, WBC, and platelets in circulating blood to decrease. Body becomes more susceptible to infection and to hemorrhage. Death occurs in 6-8 weeks in some who receive a whole body dose of 2 Gray, larger doses will cause death sooner. If a sublethal dose of 1-2 Gray pt may recover in 3-6 weeks.
