Radiation tolerance of the vaginal mucosa
International Journal of Radiation Oncology*Biology*Physics, 1979Abstract 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, 1987This 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, 1994Each 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.

Radiation Tolerance of NROM Embedded Products
IEEE Transactions on Nuclear Science, 2010Radiation 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.

Radiation tolerance of the cervical spinal cord
International Journal of Radiation Oncology*Biology*Physics, 1989The incidence of permanent injury to the spinal cord as a complication of radiation therapy generally correlates positively with total radiation dosage. However, several reports in the literature have indicated that fraction size is also an important factor in the development or nondevelopment of late injuries in normal tissue.

Radiation-induced tolerance in the immunological response is fundamentally a result of cell death and necrosis of lymphatic and hematopoietic tissues. The energy of ionizing radiation is absorbed in a physical sense in tissue, primarily by ionizing water, yielding extremely reactive chemical products of water, which in turn alter macromolecules in ...

Modeling and Optimization of Radiation Tolerant Microsystems
2014 European Modelling Symposium, 2014In the paper, several approaches to modeling and optimization of radiation tolerant microsystems are discussed. In a contrast to traditional approaches, microsystems are designed and manufactured at multiple length scales. It is shown that a multiscale approach should be used in modeling and optimization of microsystems.

A SPECIFIC IMMUNOLOGICAL TOLERANCE IN RADIATION CHIMERAS
Plastic and Reconstructive Surgery, 1962Repopulation of the bone marrow and lymph nodes with donor-type cells was demonstrated in C57BL/Rij and (CBA/Rij x C57BL/Rij)F/sub 1/ mice that had been exposed to a lethal dose of total body x irradiation and treated with CBA bone marrow cells. No apparent symptom s of secondary disease were found in those chimeras that survived 100 days after ...

RADIATION TOLERANCE OF THE THORACIC SPINAL CORD
American Journal of Roentgenology, 1969Three instances of radiation myelitis of the thoracic spinal cord were found among 350 patients treated for carcinoma of the lung, esophagus, and trachea, or for thymic tumors, 40 of whom survived more than 18 months. These 3 patients and the 37 additional patients surviving more than 18 months after irradiation were studied in detail.The time-dose ...

The radiation-tolerant x-ray monitor
Review of Scientific Instruments, 2008A vacuum photoelectric detector (monitor) (VPD) designed for plasma tomography, megnetohydrodynamics monitoring, and imaging with the help of thermal x-ray radiation on the ITER facility is described. Laboratory experiments demonstrate that VPD has high sensitivity to thermal x rays and low sensitivity to hard gamma rays and neutrons.
