Blue Worksheet Flashcards
Stochastic somatic effects
Probabilistic effects
Gas that decays with a half-life of 3,8 days by the way of alpha particle emission
Radon
Implies that the biological response to ionizing radiation is directly proportional to the dose
Liner nonthreshhold dose-response curve
Predicts that the number of excess cancer will increase as the natural incidence of cancer increases in pop. with advancing age
Relative risk model
Hematopoietic form of ARS
Bone marrow syndrome
Est. the risk associated with low-level radition
Linear quadratic, nonthreshhold dose- response curve
Radioactive contrast agent used from 1925-1945 that caused liver and spleen cancer after a latent period of 15-20 years
Thorotrast
Reported in 1995 that nearly 700 cases of third cancer among children and adolescents were liked to the chernobyl accident
World Health Organization (WHO)
Froms of ARS that results when the central nervous system and cardiovascular system receive ionizing radiation doses of 50 GY (5000 rads) or more
Cerebrovascular syndrome
Nonstochastic Somatic effects
Deterministic Effects
Radition sickness that occurs in human being after whole-body radiation 1 Gy (100 rads) or more delivered over short time
ARS
Predicts that a specific # of excess cancers will occur as a results of exposure to ionizing radiation
Absolute Risk Model
a collection of symptoms
syndrome
The first stage of ARS, which occurs within hours after whole body absorption of 1 Gy (100rads) or more; it is characterized by nausea, vomiting, diarrhea, fatigue, and leukopenia
Prodromal Stage
From of ARS that appears at a threshold dose of approx. 6 Gy (600rads)
Gastrointestinal Syndrome
