Measurements of the ambient dose equivalent rates around the Manyoni uranium deposit in Tanzania

open access: yesBrazilian Journal of Radiation Sciences, 2023
In this study, pre-mining ambient gamma dose equivalent rates at 1 m above the ground were measured using a Gamma-Scout portable radiation survey meter at two sites, A and B, around the Manyoni uranium deposit in Tanzania.

THE IN-SITU CALIBRATION METHOD FOR AMBIENT DOSE EQUIVALENT DOSEMETERS

open access: yesRadiation Protection Dosimetry, 2021
Abstract Ambient dose equivalent dosemeters are widely distributed in nuclear facilities for routine continuous monitoring or nuclear accident emergency monitoring, they are inconvenient to be disassembled and sent to the metrology laboratory for calibration.

Neutron dosimetry at workplaces of JC “Institute of Nuclear Materials”

open access: yesРадиационная гигиена, 2021
If the neutron fields at personnel workplaces differ from the neutron fields in which individual dosimeters are verified, there is a possibility of additional errors in the assessment of such dosimetric quantities as ambient dose equivalent, individual ...

Model for Reconstruction of γ-Background during Liquid Atmospheric Precipitation

open access: yesMathematics, 2021
With regard to reconstructing the gamma background dose rate, existing models are either empirical with limited applicability or have many unknown input parameters, which complicates their application in practice.

EVALUATION OF AMBIENT DOSE EQUIVALENT SURROUNDING TRANSMISSION FULL-BODY SCANNERS

open access: yesRadiation Protection Dosimetry, 2020
Abstract This study analyses the ambient dose equivalent around transmission full-body scanners used in Brazilian prisons and airports. In order to achieve this goal, three transmission full-body scanners of the same model assembled by a Brazilian manufacturer were evaluated.

Characterization of the Secondary Neutron Field Produced in a Thick Aluminum Shield by 1 GeV/u 56Fe Ions Using TLD-Based Ambient Dosimeters

open access: yesFrontiers in Physics, 2020
The neutron ambient dose equivalent induced by galactic cosmic-ray-like (1 GeV/u 56Fe) radiation stopped in a thick aluminum shield was measured at different angles with a GSI neutron ball, the standard TLD (thermoluminescent dosimeters)-based neutron ...
