It takes on average 333 eV to liberate an electron-hole pair in a NaI detector (100 times more that Ge), therefore 1 keV of photon energy produces 3 photoelectrons in NaI. It takes, on average, 33.7 eV to liberate an ion pair in air. Considering only the counting statistics aspect of the difference, how will the FWHM for an ion chamber compare with that for a NaI detector? How will the FWHM for a Ge detector compare with that for a NaI detector? Provide a numerical answers.
