Evaluation of neutron sensitivity for a personnel dosimeter using type-K nuclear emulsion

In the composition of the type-K emulsion used in personnel neutron dosimetry, nitrogen [5] appears along with other elements. Through the action of thermal neutrons, the reaction Nt4(n, p)C 14 takes place in the emulsion with the emission of protons having an energy in the neighborhood of 6 MeV. The range of these protons in the emulsion is approximately 6t~. The number of protons, N(E), created per cm 2 of emulsion during its irradiation by neutrons with an energy E can be determined from N (E) = ~p (E) ~ (E) A,
