Biological Effects of Space Radiation
The radiation exposure in space missions can be reduced by appropriate measures, but it cannot be prevented. The reason is that space radiations due to their high energy deeply penetrates in matter. In comparison to the shielding thickness of the atmosphere of approximately 10 meter water equivalent, a spacecraft provides only 1-30 cm shielding depending on the equipment installed inside the sp...
متن کاملA phase-space beam position monitor for synchrotron radiation
The stability of the photon beam position on synchrotron beamlines is critical for most if not all synchrotron radiation experiments. The position of the beam at the experiment or optical element location is set by the position and angle of the electron beam source as it traverses the magnetic field of the bend-magnet or insertion device. Thus an ideal photon beam monitor would be able to simul...
متن کاملRadiation dosimetry and biophysical models of space radiation effects.
Estimating the biological risks from space radiation remains a difficult problem because of the many radiation types including protons, heavy ions, and secondary neutrons, and the absence of epidemiology data for these radiation types. Developing useful biophysical parameters or models that relate energy deposition by space particles to the probabilities of biological outcomes is a complex prob...
متن کاملRadiation measurements in secondary elctron beam and comparison with calculations.
A high energy particle beamline is described which is capable of transporting a high intensity electron beam to potentially occupied areas. Ionization chamber measurements of electron beam intensity are described together with the ion chamber calibration and necessary corrections. The results of the measurements are compared with a Monte Carlo calculation of the electron intensity. (Submitted t...
متن کاملDeleterious effects of electron beam radiation on allergen extracts.
BACKGROUND The recent threat to the public posed by the dissemination of Bacillus anthracis through the US postal system has resulted in increased security measures, including electron beam irradiation for the sterilization of some mail. The deleterious effects of electron beam radiation on biological products are not fully understood. OBJECTIVE The purpose of this investigation was to assess...
