Partial Volume Tolerance of the Liver to Radiation

Seminars in Radiation Oncology, 2005
The use of conformal radiotherapy (RT) and the follow-up of patients for radiation liver toxicities has led to a quantitative understanding of partial liver RT tolerance. The most common toxicity is radiation-induced liver disease (RILD), a syndrome of anicteric ascites and hepatomegaly.

Radiation Tolerance of NROM Embedded Products

IEEE Transactions on Nuclear Science, 2010
Radiation tolerance of NROM memories is demonstrated at the level of industrial 4 Mbit memory embedded modules, specifically not designed for operation in radiation harsh environments. The memory fabricated in 0.18 um technology remains fully functional after total ionization doses exceeding 100 krad.

Hypocaloric Feeding and Radiation Tolerance

Radiation Research, 1961
Experiments were performed to compare the radiation sensitivity and the dose mortality curves of hypocalorically reared rats and freely fed controls. The radiation resistance of hypocalorically reared rats is significantly reduced when compared to freely fed controls.

RADIATION TOLERANCE LIMITS OF THE BRAINSTEM

Neurosurgery, 2008
One of the key limitations of gamma knife surgery arises from the radiation safety tolerance limit of the brainstem. The authors conducted an analysis of patients with intra-axial brainstem lesions and documented the incidence of adverse radiation imaging effects (ARIE) and new neurological deficits after gamma knife surgery.Thirty-eight patients (39 ...

Radiation Tolerance of Complex Oxides

Science, 2000
The radiation performance of a variety of complex oxides is predicted on the basis of a material's propensity to accommodate lattice point defects. The calculations indicate that a particular class of oxides possessing the fluorite crystal structure should accept radiation-induced defects into their lattices far more readily than a structurally similar

Carbon Nanotubes for Radiation-Tolerant Electronics

ACS Nano, 2021
Electronics for space applications have stringent requirements on both performance and radiation tolerance. The constant exposure to cosmic radiation damages and eventually destroys electronics, limiting the lifespan of all space-bound missions. Thus, as space missions grow increasingly ambitious in distance away from Earth, and therefore time in space,

Radiation tolerance of the vaginal mucosa

International Journal of Radiation Oncology*Biology*Physics, 1979
Abstract Sixteen patients with cancer of the vagina that were controlled locally for a minimum of eighteen months after teletherapy (T) or brachytherapy (B) or both (T & B), were analyzed for radiation tolerance of the vaginal mucosa. The site of vaginal necrosis did not always coincide with the site of the tumor.

A Radiation Tolerant Photodetector

IEEE Transactions on Nuclear Science, 1987
This paper describes the development and test of a radiation tolerant photodetector. This was accomplished by building a single stage photo multiplier tube with a physically small, dielectrically isolated, silicon photodiode array at the anode. In this device the optically generated photocurrent is multiplied by a much larger factor than is the photo ...

Spinal cord radiation tolerance

International Journal of Radiation Oncology*Biology*Physics, 1994
Each case of radiation myelopathy represents a unique occurrence where an individual’s tolerance was exceeded. Therefore, each case offers the challenge to determine why this patient’s tolerance was exceeded at a dose that other patients tolerate.
