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

Low-dose Pretreatment for Radiation Therapy
Dose-Response, 2010 In radiotherapy, a large radiation dose must be applied to both cancer and neighboring healthy cells. Recent experiments have shown that a low dose of ionizing radiation turns on certain protective mechanisms that allow a cell to better survive a ...

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

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