Radiation Protection Study Guide Questions And Correct Answers

Units of Radiation Measurement (International System) SI {Ans: 1) Coulomb/Kilogram 2) Gray 3) Sievert 4) Becquerel}When do you use shielding {Ans: you must shield everyone of reproductive age (males and females)}Diagnostic "X-ray" Radiation {Ans: Is classified as Low energy LET radiation}Non-Threshold {Ans: Any amount of radiation has an effect}Somatic Effect (Early vs Late) {Ans: Early effects - will happen within a set amount of time based on the absorbed dose. Late effects - can happen later 1 year or more after radiation dosage - based on amount of absorbed dose.}Thickness of Glove shields {Ans: 0.25mm lead}Major Types of Scatter {Ans: 1) Coherent Scatter 2) Photoelectric Scatter 3) Compton Scatter}Law of Bergonie and Tribondeau {Ans: Deals with the radio sensitivity of cells to radiation. The Law states that a cells radio sensitivity is directly proportional to their reproductive activity and inversely proportional to their degree of differentiation.}R. B. E. {Ans: Relative Biological Effectiveness}Sievert {Ans: SI Unit of equivalent dose and affective dose * Traditional Unit name would be REM}Example of Non-Stochastic effect and there threshold {Ans: *) Temporary Sterility - 200rems *) Permanent Sterility - 500rems *) Erythemia (red skin)
