ICRP (ICRP Publication 74 [1]) and ICRU (ICRU Report 57 [2]) recommended conversion coefficients for use in radiological protection for electrons and photons of energies up to 10 MeV and for neutrons up to 180 MeV. For various purposes conversion coefficients for higher energies and other kind of radiation are needed: for this reason sets of fluence-to-effective dose and fluence-to-ambient dose equivalent conversion coefficients for all kind of radiation (photons, electrons, positrons, protons, neutrons, muons, charged pions and kaons) and for incident energies (up to 10 TeV) of practical interest have been calculated in recent years using the FLUKA code [6]-[20].

All conversion coefficients have been calculated using the same methodology (same code, same geometry, same rules), they therefore constitute a coherent system of dosimetric data. The calculated conversion coefficients can be found on this web site (zip, tar.gz). In this documentation information can be found about the calculation methodology, the use of conversion coefficients and the papers to cite when using them for radiation protection calculation.
