Dose Equivalents in Anthropomorphic Phantoms and their Relation to the Ambient Dose Equivalent H*(10) for External Exposure

Radiation Protection Dosimetry, 1989
Abstract The ICRP has recommended a system of dose limitation based on the dose equivalents in various organs and on the effective dose equivalent HE. Because HE is unmeasurable, it was agreed to estimate HE on the basis of dose equivalents in the ICRU sphere.

Total Ambient Dose Equivalent Buildup Factor Determination for Nbs04 Concrete

Health Physics, 2018
Abstract Buildup factors are dimensionless multiplicative factors required by the point kernel method to account for scattered radiation through a shielding material. The accuracy of the point kernel method is strongly affected by the correspondence of analyzed parameters to experimental configurations, which is attempted to be simplified ...

Correction Coefficients for Measuring the Ambient Dose Equivalent Rate of Neutrons

ANRI, 2021
Calculations of the response for the most widely used neutron dosimeters at the Russian nuclear power plant (NPP) have been performed. It is shown that in some cases it is necessary to introduce a correction for the measured value of the ambient dose equivalent rate (AEDR).

Ambient Dose Equivalent in S. Paulo and Bauru cities

AIP Conference Proceedings, 2008
The 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

Ambient Dose Equivalents, Effective Dose Equivalents, and Effective Doses for Neutrons from 10 to 20 MeV

Radiation Protection Dosimetry, 1993
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.

In-flight measured and predicted ambient dose equivalent and latitude differences on effective dose estimates

Radiation Protection Dosimetry, 2004
The results from 2 years (2001-2002) of experimental measurements of in-board radiation doses received at IBERIA commercial flights are presented. The routes studied cover the most significant destinations and provide a good estimate of the route doses as required by the new Spanish regulations on air crew radiation protection.

Calculations of Effective Dose and Ambient Dose Equivalent Conversion Coefficients for High Energy Photons

Journal of Nuclear Science and Technology, 1999
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.

Determination of ambient and personal dose equivalent for personnel and cargo security screening

Radiation Protection Dosimetry, 2006
In the past few years, imaging technology using ionising radiation has been gaining in importance for the screening of goods and persons for security reasons and in order to detect contraband. For radiation protection purposes it is extremely important to know that dose persons are exposed to when passing through a personnel scanner or, as a stowaway ...

Model of ambient dose equivalent for radium contamination: Dependence on the geometry of the source

Journal of Environmental Radioactivity, 2018
Industrial activities involving radium sources, such as watchmaking, were still common up until the 1960s. They produced contaminations in building materials and the soil in a large variety of geometries. The potential remediation of such places requires instruments that are properly calibrated as well as adequate procedures.
