1. Consider two monoenergetic photon beams with the same photon fluences. In one beam the photons are 100 keV and in the other they are 1 MeV. Determine the most appropriate relation between both exposures (X).
2. Electrons with kinetic energy of 1.0 MeV have a speci c ionization in air of 6000 IP/m whereas alpha particles of 2.0 MeV have an LET in air of 0.175 keV/μm. What value is closest to the ratio LET(alphas)/LET(electrons) in air.
