Research on Calculation Method of Radiation Response Eigenvalue of a Single-Chip Active Pixel Sensor

open access: yesSensors, 2022
In this paper, we present a calculation method for the radiation response eigenvalue based on a monolithic active pixel sensor. By comparing the statistical eigenvalues of different regions of a pixel array in bright and dark environments, the linear ...

A hypothesis to derive the shape of the dose–response curve for teratogenic radiation effects

open access: yesEnvironmental Health, 2022
Reports of adverse pregnancy outcomes after in utero exposure to very low levels of ionizing radiation are inconsistent with a threshold dose of 100 mSv for teratogenic effects in humans.

Dose rate effect on mortality from ischemic heart disease in the cohort of Russian Mayak Production Association workers

open access: yesScientific Reports, 2023
For improvement of the radiation protection system it is crucial to know the factors that modify the radiation dose–response relationship. One of such key factors is the ionizing radiation dose rate.
