WebA) They are very reactive elements. B) They have the lowest first ionization energies of the elements. C) They are low density solids at room temperature. D) They all readily form … WebThe EGSnrc Monte Carlo code was used for all calculations modelling the ionization chambers and for the depth doses in a water phantom. The kilovoltage x-rays used were based on the x-ray beams at the Physikalisch-Technische Bundesanstalt (PTB) in the energy range from from 50 kVp (HVL: 0.073 mm Cu) to 300 kVp (HVL 3.592 mm Cu).
