Personal dose equivalent conversion coefficients for neutron fluence over the energy range of 20-250 MeV

Neutron Energy Spectra and Dose Equivalent Rates from Heavy-ion Reactions below 20 Mev/u Using the Phits Code *

Neutron energy spectra from 6.25 MeV/u C ions incident on a copper target, 10 MeV/u C ions incident carbon, copper, and lead targets, and O ions incident on a copper target have been calculated using the Quantum Molecular Dynamics model (QMD) [1] coupled to the Generalized Evaporation Model (GEM) [2] in the Particle and Heavy Ion Transport Code (PHITS) [3]. In particular, the influence of the “...

Tritons at energies of 10 MeV to 1 TeV: conversion coefficients for fluence-to-absorbed dose, equivalent dose, effective dose and gray equivalent, calculated using Monte Carlo radiation transport code MCNPX 2.7.C.

Conversion coefficients were calculated for fluence-to-absorbed dose, fluence-to-equivalent dose, fluence-to-effective dose and fluence-to-gray equivalent for isotropic exposure of an adult female and an adult male to tritons ((3)H(+)) in the energy range of 10 MeV to 1 TeV (0.01-1000 GeV). Coefficients were calculated using Monte Carlo transport code MCNPX 2.7.C and BodyBuilder™ 1.3 anthropomo...

Fast Neutron Absorbed Dose Distribution Characteristics in the Energy Range 10–80 MeV

Development and Characterization of a Neutron Personal Dose Equivalent Monitor

The authors developed a new neutron-measuring instrument that was designed to measure a neutron personal dose equivalent, Hp(10). This instrument is composed of a conventional moderator-based neutron dose equivalent meter and a neutron shield made of borated polyethylene which covers a backward hemisphere to adjust the angular dependence. The whole design was determined on the basis of MCNP cal...
