PHYSICOCHEMICAL work shows that ionizing radiations cause fragmentation and aggregation of protein molecules1–3. When protein molecules are degraded there is a variety of products and also many amino-acids are degraded. However, the mechanisms by which these changes occur are still obscure.

Radiation Damage to Dihydrouracil
Radiation Research, 1978EGTVEDT, I., SAGSTUEN, E., BERGENE, R., AND HENRIKSEN, T. Radiation Damage to Dihydrouracil. Radiat. Res. 75, 252-268 (1978). Single crystals of dihydrouracil, grown from D20 solutions, were irradiated with 4.0-MeV electrons at 77 K. Electron spin resonance techniques were used to study radiation-induced radicals in the temperature range from 77 to 295

Microvasculature and Radiation Damage
1993The association between late damage in irradiated tissues and the vasculature was reported shortly after the discovery of X-rays. Gross blood vessel abnormalities were a consistent finding in radiation-damaged tissues (Gassmann 1899; Muhsam 1904). Since then there have been numerous pathology reports emphasizing the significance of vascular damage in ...

Kidney Damage by Ionizing Radiation
European Urology, 1981The report describes a case of radiation damage to a kidney due to radiotherapy of a sarcoma of the muscles of the back. The characteristic clinical, pathological and histological findings and the results of X-ray investigation are presented in detail.

The Parathyroid as a Target for Radiation Damage
New England Journal of Medicine, 2011To the Editor: Exposure to radiation may result in late adverse effects. Here we describe the consequences of irradiation for the endocrine system, particularly the parathyroid glands, in a cohort of 61 “liquidators,” or cleanup workers, who participated in the effort to contain the contamination at the Chernobyl nuclear power plant in Ukraine ...

Delocalized radiation damage in polymers
Micron, 2012We present and discuss measurements of electron-irradiation damage in polystyrene and other polymers, based on fading of the 7-eV energy-loss peak. These measurements suggest a large increase in characteristic dose as the electron-beam diameter is reduced from 1 μm to below 1 nm.

A Cytogenetic Profile of Radiation Damage
Radiation Research, 2018Most of the important biological effects associated with the exposure to ionizing radiations are mirrored at the chromosomal level. In all cases, changes in the levels of cytogenetic effects are associated with changes in absorbed dose, dose rate and radiation quality.

Radiolytic Radiation Damage of Sodalite
Physica Status Solidi (a), 1978“In situ” electron irradiation of sodalite in the transmission electron microscope (TEM) results in formation of radiolytic damage in the form of chlorine ion voids and chlorine gas bubbles. The chlorine ion-voids are identical with metallic sodium particles. The damaging process is discussed in terms of point defects and radiation induced voidage. The

Radiation-related damage to dentition
The Lancet Oncology, 2006Because of typical tissue reactions to ionising radiation, radiotherapy in the head and neck region usually results in complex oral complications affecting the salivary glands, oral mucosa, bone, masticatory musculature, and dentition. When the oral cavity and salivary glands are exposed to high doses of radiation, clinical consequences including ...

Heat Potentiation of Radiation Damage versus Radiation Potentiation of Heat Damage
Radiation Research, 1987The enhanced lethality of mammalian cells after combined treatment with hyperthermia and radiation is usually attributed to heat potentiation of radiation damage. However, it has been suggested that the situation may be reversed and that radiation may act as a modifier for heat damage.
