“Povera E Nuda Vai, Dosimetria” [PDF]
Health Physics, 1972 Abstract The concepts used in radiation protection are critically reviewed. It is concloaed that primary attention should be given to the specification of radiation fields in terms of particle flux density and energy spectra, from which all other parameters needed in health physics may be derived.
