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

Радиационная 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 ...

Range-shifter effects on the stray field in proton therapy measured with the variance–covariance method

Frontiers in Oncology, 2022
Measurements in the stray radiation field from a proton therapy pencil beam at energies 70 and 146 MeV were performed using microdosimetric tissue-equivalent proportional counters (TEPCs).

Model for Reconstruction of γ-Background during Liquid Atmospheric Precipitation

Mathematics, 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.

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

Frontiers 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 ...

Total Ambient Dose Equivalent Buildup Factors for Portland Concrete

Health Physics, 2018
Abstract In this work, total ambient dose equivalent buildup factors for Portland concrete slabs are calculated using Monte Carlo n-particle software MCNP6™. Buildup factor calculations could approach intractable solutions in general as they depend on a large number of variables.

Assessment of annual effective dose from external exposure in forests of the south-western districts of the Bryansk region of Russia: 2015–2021

Радиационная гигиена, 2022
During a stay in a radioactively contaminated forest, a person is inevitably exposed to ionizing radiation from the man-made radionuclides. The purpose of this study was to evaluate the external component of the annual effective dose due to exposure in ...
