Study of Low-Dose Radiation Workers Ionizing Radiation Sensitivity Index and Radiation Dose-Effect Relationship

Health Physics, 2022
Background In the present study, we analyzed radiation injuries to Chinese workers exposed to low-dose radiation. We discuss the relationships between dose and injury. Methods This study randomly selected 976 radiation workers who underwent occupational health monitoring.

Variability of Radiation Dose-Effect Regressions

Acta Radiologica, 1959
Weight changes in the optic lens of the rabbit caused by somatic radiation damage are described and discussed as demonstrating a variability of the dose-effect regression. (auth)

Dose and dose rate effectiveness of space radiation

Radiation Protection Dosimetry, 2006
Dose and dose rate effectiveness factors (DDREF), in conjunction with other weighting factors, are commonly used to scale atomic bomb survivor data in order to establish limits for occupational radiation exposure, including radiation exposure in space. We use some well-known facts about the microscopic pattern of energy deposition of high-energy heavy ...

Effective dose: a radiation protection quantity

Annals of the ICRP, 2012
Modern radiation protection is based on the principles of justification, limitation, and optimisation. Assessment of radiation risks for individuals or groups of individuals is, however, not a primary objective of radiological protection. The implementation of the principles of limitation and optimisation requires an appropriate quantification of ...

Biological low-dose radiation effects

Mutation Research/Reviews in Genetic Toxicology, 1991
It is theorized that biological responses to ionizing radiation in the low dose range are determined according to a doubly dichotomous pattern. Energy depositions fall into 2 categories: events at thermal energy levels where they may be experienced by cells as rates even at background exposure conditions, and events at energy levels of the order of 10 ...

Low-dose Radiation Effects

Health Physics, 1990
Experimental data from the author's laboratory are discussed, which demonstrate mutagenic and carcinogenic effects of low dose and low dose-rate exposure to ionizing radiation, and the modification of these effects by various chemical agents. These data are derived from studies of mutagenesis and neoplastic transformation in vitro, as well as on the ...
