Lymphocyte Depletion Rate as a Biomarker of Radiation Dose to Circulating Lymphocytes During Fractionated Partial-Body Radiation Therapy [PDF]

, 2022
PURPOSE: Radiation causes exponential depletion of circulating lymphocyte populations; in turn, radiation-induced lymphopenia is associated with worse survival for many solid tumors, possibly owing to attenuated antitumor immune responses.

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 ...

Low dose ionising radiation produces too few ROS to directly affect antioxidant concentrations in cells [PDF]

, 2012
It has been hypothesized that radiation-induced oxidative stress is the mechanism for a wide range of negative impacts on biota living in radioactively contaminated areas around Chernobyl.

Analysis of repeated computed tomography scans and cumulative effective dose of patients in a hospital

Brazilian Journal of Radiation Sciences, 2023
Computed tomography exams are considered diagnostic imaging exams that generate significant radiation dose to the patient. Justification, optimization, and dose limitation are radiological protection principles used to minimize patient and staff exposure,

Transcriptome analysis of low-dose ionizing radiation-impacted genes in CD4+ T-cells undergoing activation and regulation of their expression of select cytokines

Journal of Immunotoxicology, 2018
Immune cells are known as the most sensitive tissue for ionizing radiation. Numerous reports relating with the effect of low-dose ionizing radiation (LDIR) on immune activities showed that LDIR can induce immune-potentiation via modulating the activity ...

Enhanced Radiation-Induced Narrow Channel Effects in Commercial 0.18 μm Bulk Technology [PDF]

, 2011
Total ionizing dose effects are investigated in input/output transistors that are fabricated by using a commercial 0.18 μm bulk process. An enhanced radiation-induced narrow channel effect is demonstrated in N-type metal-oxide semiconductor (NMOS) and P ...

Tissue distribution, excretion and effects on genotoxicity of tritium following oral administration to rats

Nuclear Engineering and Technology, 2019
Tritium is an important nuclide that must be monitored for radiation safety management. In this study, HTO was orally administered to rats at the level of 37 kBq (1 μCi) or 370 kBq (10 μCi) to examine tissue distribution and excretion levels.
