It can be used for proton dosimetry if the protons are over 30 MeV. Expose the foil to the proton beam, then put it in a HPGe scintillator and look for Na24 gamma photons. Determine the amount of Na24 that was created at exposure time, and using the cross section, calculate how many protons hit the foil. This method avoids the obvious problems using CaF2:Mn as it’s not sensitive to beam photons.
