A deterministic effect: Select one: O A. Has no threshold in dose and the severity of the effect increases with dose B. Has no threshold in dose and the severity of the effect is a constant function of dose OC. Has a threshold in dose but the severity of the effect is otherwise dose-independent. D. Has a threshold in dose and the severity of the effect increases with dose
The annual dose limit for decupational CA. All ionizing radiations B. Beta. X, and gamma radiations C. X and gamma radiations only D. Alpha, Beta, and X-radiations
Which of the following statements is false? A. The severity of a stochastic effect increases with dose. A cancer induced by 1 Gy is not worse than a cancer induced by 0.5 Gy. C. Stochastic effects have no threshold in dose. D. The probability of induction of a stochastic effect increases with dose. Clear my choice
Calculate the ALI for the inhalation of class w 118mcd given the following data: Uniteye - 1.7x107 Bq.s, Ulivet - 1.7x107 Bq.s per 1Bq of intake. SEB (kidneys + Kidneys) =6x10 - Mev/g per one Transformation, SEE (Liver - Liver) -1x10-* MeV/g per one Transformation. Wy = 0.06 for Kidney and Liver
What is the absorbed dose rate in water due to a monodirectional flux of 1x104 photons/cm2.s, which have a stopping power of 300 MeV/cm? A. 480 mrad/s B.0.48 mrad/s C. 4.8 mrad/s D. 48 mrad/s
The atomic cross sections for 1-MeV photon interactions with carbon and hydrogen are, respectively, 1.27 barns and 0.209 barn. (a) Calculate the linear attenuation coefficient for paraffin. (Assume the composition CH2 and density 0.89 g/cm².) (b) Calculate the mass attenuation coefficient. 1 barn = 10-24 cm2
