Radiation Protection Dosimetry, 1988
Abstract The results of calculations for the attenuation of the giant-resonance neutron spectra produced at an electron accelerator in various shielding materials are presented. As the spectra are similar to those of some radioactive sources, a comparison is made with Cf and Am-Be sources.

The Design of an Ambient Neutron Dose-Equivalent Meter
Journal of Engineering for Gas Turbines and Power, 2011At present, most of the developed neutron dosimeters used to measure the neutron ambient dose-equivalent that has a moderator with a single counter, applied in neutron radiation fields within large range energies from thermal to MeV neutrons, are not a satisfaction to energy response.

Ambient Dose Equivalent in S. Paulo and Bauru cities
AIP Conference Proceedings, 2008The Laboratory of Dosimetry (Institute of Physics, University of S. Paulo) performs since 1981 the external individual monitoring of workers exposed to X and gamma rays based on thermoluminescent dosimetry (TLD). Personal dose equivalent refers only to the exposure of workers due to the working activities, and the dose due to background radiation, also

Monte Carlo calculations of dose quantities have been performed using the PNL male and female anthropomorphic phantoms for neutrons between 10 and 20 MeV for the AP, PA, L-LAT, R-LAT, and ROT irradiation geometries. The impacts of the new radiation protection quantities recommended by ICRP 60 were explored.

Estimating the terrestrial gamma dose rate by decomposition of the ambient dose equivalent rate
Journal of Environmental Radioactivity, 2017An extensive network of dose rate monitoring stations continuously measures ambient dose rate across Europe, as part of the EURDEP system. Its purpose is early warning in radiological emergencies and documenting its temporal and spatial evolution.

Correlation of the ambient dose equivalent rate and meteorological parameters
Journal of Radioanalytical and Nuclear Chemistry, 2020In this paper, the results of ambient dose equivalent rate measurements at different locations are presented. At every location measurements were performed twice a day, in the morning and afternoon. One of the aim of this study was to determine the impact of weather conditions on the ambient dose equivalent rate.

The conversion coefficients from photon fluence to ambient dose equivalent, H* (10) and effective doses were calculated for photons up to 10 GeV. A Monte Carlo code EGS4 was used for these calculations and secondary particle transports were considered. The calculated ambient dose equivalents were compared to the calculated effective doses.

Detailed depth-dose calculations were performed in the ICRU sphere for monoenergetic parallel neutron beams with energies ranging from 30 MeV to 180 MeV. Fluence-to-dose conversion coefficients were obtained for both absorbed dose and dose equivalent quantities.

Abstract A comparison between neutron physics lists given by GEANT4, is made in the calculation of the ambient dose equivalent, and ambient absorbed dose, per fluence conversion coefficients ( H * ( 10 ) / ϕ and D * ( 10 ) / ϕ ) for neutrons in the range of 10−9 MeV to 15 MeV.
