  1. Q 1. The Compton effect is A. Photon’s entire energy is used to eject an electron B. Photon’s entire energy is used to eject an electron and low energy photon C. Photon’s entire energy is used to eject an negative and one positive electron D. Photon energy is absorbed by colliding by hydrogen nuclei

  2. Q2. Accelerated fractionation is described as • 1.7 to 2.0 Gy, 5 fraction/week to 70.0Gy • B. Reduction of the number of fraction with an increase of the daily fraction • Increase both the number of fractions and the total dose • Hybrid state of hypofractionation and hyperfractionation

  3. Q3. The characteristic property of particulate radiation in comparison to photo radiation in dosimetry is • A. falloff region is rapid • B. skin sparing effect is more • C. higher the energy used, the greater the depth of penetration • D. progressive fall of tissue dose
