Abstract
A personnel neutron dosimeter consisting of a single recorder and a (n, .alpha.) radiator wherein exposure to two levels of neutron energy produces differing plural forms of damage sites in the recorder, which damage sites, upon development, will differ sufficiently in character or as to location on the recorder to permit separate identification and measurement of the neutron dose received from two portions of the neutron spectrum.
