Estimation of Ambient Dose Equivalent Rate Distribution Map Using Walking Survey Technique in Hirosaki City, Aomori, Japan. [PDF]

Int J Environ Res Public Health, 2023
At present, much emphasis is placed on the health risks associated with radioactivity present in the environment, especially since the accident at the Fukushima Daiichi Nuclear Power Plant. In this study, a walking survey was conducted in Hirosaki City using a NaI(Tl) scintillation spectrometer to estimate and map the distribution of the ambient dose ...

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

Brazilian 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.

Initial decrease in the ambient dose equivalent rate after the Fukushima accident and its difference from Chernobyl. [PDF]

Sci Rep, 2020
AbstractIn 2011, after the Fukushima Dai-ichi Nuclear Power Plant accident, the initial decrease in the ambient dose equivalent rate (dH*(10) dt−1), an alternative quantity to the effective dose, was studied using monitoring data obtained from March 16, 2011.

PROCEDURES TO MEASURE MEAN AMBIENT DOSE EQUIVALENT RATES USING ELECTRET ION CHAMBERS [PDF]

Radiation Protection Dosimetry, 2020
Abstract The capabilities of electret ion chambers (EICs) to measure mean ambient dose equivalent rates were investigated by performing both laboratory and field studies of their properties. First, EICs were ‘calibrated’ to measure ambient gamma dose equivalent in the Ionizing Calibration Laboratory of the Greek Atomic Energy Commission.

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.
