Proton and heavy ion acceleration facilities for space radiation research.
The particles and energies commonly used for medium energy nuclear physics and heavy charged particle radiobiology and radiotherapy at particle accelerators are in the charge and energy range of greatest interest for space radiation health. In this article we survey some of the particle accelerator facilities in the United States and around the world that are being used for space radiation heal...
متن کاملRadiobiological Research with Charged Particles Beams in Itep
Radiobiological researches with heavy ions have been started at ITEP in 2006 on unique heavy ion accelerating facility ITEP-TWAC. The main purpose of these researches is study of the biological efficiency of carbon ions for different types of biological objects, such as tumor and normal cells, in the framework of the development of heavy ion therapy for cancer treatment in Russia. Another possi...
متن کاملInduction of cancer stem-like cells in A549 cells after exposure to carbon ions and X-rays
Background: Cancer stem-like cells (CSCs) play a crucial role in the initiation, progression, and recurrence of cancer. Evidence indicates that the high linear energy transfer (LET) carbon ion beam is more effective against CSCs than the conventional X-ray beam. Carbon ion radiotherapy is considered as a promising cancer strategy, however, information about whether, or not, new CSCs are induced...
متن کاملIssues for Simulation of Galactic Cosmic Ray Exposures for Radiobiological Research at Ground-Based Accelerators
For radiobiology research on the health risks of galactic cosmic rays (GCR) ground-based accelerators have been used with mono-energetic beams of single high charge, Z and energy, E (HZE) particles. In this paper, we consider the pros and cons of a GCR reference field at a particle accelerator. At the NASA Space Radiation Laboratory (NSRL), we have proposed a GCR simulator, which implements a n...
متن کاملEnergy and charge localization in irradiated DNA.
The relation between the site of energy deposition and the site of its biological action is an important question in radiobiology. Even at 77 degrees K, evidence is clear that these two sites must be separated since energy deposition is random but specific products are formed. Several processes that may contribute to this separation are: 1) hole migration and stabilization through deprotonat...
