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 ...

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.

Low dose ionizing radiation effects on the immune system
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 ...

Radiation Carcinogenesis at Low Doses [PDF]
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 ...

Background Use of computed tomography (CT) for diagnostic evaluation has increased dramatically over the past two decades. Even though CT is associated with substantially higher radiation exposure than conventional x-rays, typical clinical doses are not ...

Cerebral cortex regions selectively vulnerable to radiation dose-dependent atrophy
Purpose/Objectives Neurologic deficits after brain radiotherapy (RT) typically involve decline in higher-order cognitive functions such as attention and memory rather than sensory defects or paralysis.

It is well known that the temporal dynamic of indoor and outdoor radon concentrations show complex patterns, which are partly not easy to interpret. Clearly, for physical reasons, they must be related to possibly variable conditions of radon generation ...
