What are the minimum energies of the two oppositely directed gamma rays in a PET procedure?
The point source Co-60 emits gamma with energies of 1.17 MeV and 1.33 MeV. Each of these energies emits the same number of photon particles. At a certain location, the flux that is read is 5.7 x 109 photons/cm2.s, what is the intensity or energy flux with units of J/m^2.min
During X-ray diagnostics, lead aprons made of a thin layer of lead are used in order to protect against the harmful effects of X-ray radiation. Determine, by what factor is the intensity of X-ray radiation reduced after passing the apron of thickness 0.5 mm. The mass attenuation coefficient for a radiation source with an energy of 140 keV is μm = 2 cm²/g. Density of lead ρ = 11.35 g/cm³
