On this curve the ionization maximum occurs at 1.9 mm ... when protons of the smallest energy are concerned. It is the object of the present note to point out the contrary evidence referred ...

factoring in photon energy dependence. A fluence-dependent effect on the alignment parameter was observed, indicating that ...

277/2. It describes options and how to calibrate plane parallel ionization chambers, against air kerma or absorbed dose to water standards at cobalt-60 gamma ray energies. The use of these chambers to ...
