Radiation Protection Dosimetry
Abstract This study examines the relationship between ambient dose H*, ambient dose equivalent H*(10), and effective dose E for external neutron irradiation over 163 operational spectra from different workplaces. The results show that H* provides a reasonable estimate with a controlled margin, even if overestimated, to assess E compared ...

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.

The Influence of Radon (Gas and Progeny) and Weather Conditions on Ambient Dose Equivalent Rate
Radiation Protection Dosimetry, 2016The purpose of this study is to identify the influence of radon (gas and progeny) on the ambient dose equivalent rate measured at the reference station ESMERALDA, where continuous measurements of the ambient dose equivalent rate (every 10 min) combined with activity concentration measurements of radon gas and radon progeny as well as meteorological ...

Measurement of neutron ambient dose equivalent in passive carbon‐ion and proton radiotherapies
Medical Physics, 2008Secondary neutron ambient dose equivalents per the treatment absorbed dose in passive carbon‐ion and proton radiotherapies were measured using a rem meter, WENDI‐II at two carbon‐ion radiotherapy facilities and four proton radiotherapy facilities in Japan.

Monte Carlo study of neutron-ambient dose equivalent to patient in treatment room
Applied Radiation and Isotopes, 2016This paper presents an analytical method for the calculation of the neutron ambient dose equivalent H* (10) regarding patients, whereby the different concrete types that are used in the surrounding walls of the treatment room are considered. This work has been performed according to a detailed simulation of the Varian 2300C/D linear accelerator head ...

Abstract A method was developed for the characterisation of photon radiation fields using collimated filtered Geiger-M¨ller detectors. With information produced by this equipment, calculations were made of the various monitoring quantities, HE, H*(10) and Hp(10), for a range of typical radiation environments.
