Enhancement of Bio-Protective Functions by Low Dose/Dose-Rate Radiation [PDF]

open access: yesDose-Response, 2006
Effects of low-dose-rate gamma-irradiation on the process of tumorigenesis were investigated in mice treated with a carcinogenic agent or irradiated with high dose X-rays at a high dose rate.

Enhanced Low Dose Rate Sensitivity at Ultra-Low Dose Rates [PDF]

open access: yesIEEE Transactions on Nuclear Science, 2011
We present results on the effects of ELDRS at dose rates of 10, 5, 1, and 0.5 mrad(Si)/s for a variety of commercial, radiation hardened, and ELDRS-free devices. We observed low dose rate enhancement below 10 mrad(Si)/s in several different part types. The magnitudes of the low dose rate enhancement varied substantially.

Alterations in Blood and Hippocampal mRNA and miRNA Expression, Along with Fat Deposition in Female B6C3F1 Mice Continuously Exposed to Prenatal Low-Dose-Rate Radiation and Their Comparison with Male Mice [PDF]

open access: yesCells
Our recent study revealed that continuous prenatal low-dose-rate irradiation did not induce cellular changes in the dentate gyrus of the hippocampus in male B6C3F1 mice exposed to gamma rays during prenatal development.

Conclusions and Suggestions on Low-Dose and Low-Dose Rate Radiation Risk Estimation Methodology [PDF]

open access: yesJournal of Radiation Protection and Research, 2021
Background For radiological protection and control, the International Commission on Radiological Protection (ICRP) provides the nominal risk coefficients related to radiation exposure, which can be extrapolated using the excess relative risk and excess ...

Application of the Linear-Quadratic model to targeted radionuclide therapy [PDF]

open access: yes, 2011
PhDThe principal aim of this work was to test the hypothesis that the Linear-Quadratic (LQ) model of cell survival, developed for external beam radiotherapy (EBRT), could be extended to targeted radionuclide therapy (TRT) in order to predict dose ...
