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.

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.

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 ...

Desiccation and radiation stress tolerance in cyanobacteria
Journal of Basic Microbiology, 2018Cyanobacteria are among the oldest living organisms on this planet, existing since more than 3 billion years. They are ideal organisms for investigating biological processes such as photosynthesis, respiration, circadian rhythm, photoregulation of gene expression, developmental gene rearrangements, and specialized cell differentiation.

1974
The acute radiation syndrome in man is clinically bounded by death at high dose levels and by the prodromal syndrome of untoward physiological effects at minimal levels of clinically effective exposure. As in lower animals, man experiences principally three acute modes of death from radiation exposure (Bond et al., 1965).

Spacecraft electronics design for radiation tolerance
Proceedings of the IEEE, 1988Current design practices are described and future trends in spacecraft electronics which are likely to alter traditional approaches are discussed. A summary of radiation effects and radiation tolerance requirements typically levied on spacecraft designs is provided. Methods of dealing with radiation and testability issues are considered. >

The radiation tolerance of the pig kidney
International Journal of Radiation Oncology*Biology*Physics, 1976In his paper Or-ton proposes a different definition of renal tolerance from that clearly defined in our studies.” This was the presence or absence of function in the irradiated kidney at 6 months and 2 years. These were the same for fractionated doses (Table 1).
