Carcinogenesis induced by low-dose radiation [PDF]

Radiology and Oncology, 2017
Although the effects of high dose radiation on human cells and tissues are relatively well defined, there is no consensus regarding the effects of low and very low radiation doses on the organism.

Low dose ionizing radiation effects on the immune system

Environment International, 2021
Ionizing radiation interacts with the immune system in many ways with a multiplicity that mirrors the complexity of the immune system itself: namely the need to maintain a delicate balance between different compartments, cells and soluble factors that ...

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 ...

Case report: Low-dose radiation reverses pembrolizumab resistance in melanoma [PDF]

Frontiers in Oncology
Immunotherapy has been the mainstay of the initial systemic treatment for metastatic melanoma regardless of the tumor’s genetic mutation status (Atkins et al., 2022).

PHA stimulation may be useful for FDXR gene expression-based biodosimetry [PDF]

Iranian Journal of Basic Medical Sciences, 2020
Objective(s): Nowadays, ionizing radiation (IR) has a significant contribution to the diagnostic and therapeutic medicine, and following that, health risks to individuals through unexpected exposure is greatly increased.

Radiation Carcinogenesis at Low Doses [PDF]

Science, 1972
An analysis of experimental findings indicates that the induction of a mammary neoplasm in the Sprague-Dawley rat is dependent on the action of radiation on more than one cell. Although a linear relation between incidence and x-ray dose might be consistent with available data, such a relation would be fortuitous and linear extrapolation to lower doses ...

Low-dose radiation pneumonitis [PDF]

Cancer, 1975
A case demonstrating fulminant radiation pneumonitis following a course of prophylactic whole lung irradiation at doses below 2000 rads, resulting in death, is presented. The importance of predisposing factors and the suspected "sensitizing" factor in this case are discussed.

Cellular sensitivity to low dose ionizing radiation

Journal of Radiation and Cancer Research, 2021
Cellular sensitivity to ionizing radiation is largely understood in terms of their DNA damage repair capacity. Efficient repair of DNA damage leaves irradiated cells unharmed. The observed differential responses of high doses (>500 mGy) and low doses (
