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 ...

Practical Radiation Damage-Induced Phasing
2016Although crystallographers typically seek to mitigate radiation damage in macromolecular crystals, in some cases, radiation damage to specific atoms can be used to determine phases de novo. This process is called radiation damage-induced phasing or "RIP." Here, we provide a general overview of the method and a practical set of data collection and ...

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992
Abstract The bombardment of solid surfaces with ions having energy below or close to the damage threshold can lead to the deposition of layers of crystalline material or to the formation of interesting surface compound layers. The structure of the grown materials is dependent on the extent to which the energy deposited by the incident ions enables ...

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.

1974
The depth distribution of damage energy deposited in solids by energetic ions has been calculated and results are compared with the experimental damage found in copper which has been irradiated with 1016 1-MeV protons at ambient temperature. The general form of the experimental damage profile from the transmission electron microscope measurements ...
