Thyroid Cell Irradiation by Radioiodines: A New Monte Carlo Electron Track-Structure Code
The most significant impact of the Chernobyl accident is the increased incidence of thyroid cancer among children who were exposed to short-lived radioiodines and 131-iodine. In order to accurately estimate the radiation dose provided by these radioiodines, it is necessary to know where iodine is incorporated. To do that, the distribution at the cellular level of newly organified iodine in the ...
متن کاملA Monte Carlo code for positive ion track simulation.
An ion interaction model has been described for simulating positive ion tracks in a variety of media with the capability of interfacing with several secondary electron transport codes. Data are presented for single-and double-differential cross-sections, binding energies, probability density distribution for delocalisation parameters for conductors and tissue, branching ratios and ionisation ef...
متن کاملDevelopment of Monte Carlo track structure codes
When ionizing radiation interacts with matter, by its basic definition, it produces free electrons and residual positive ions. Thus, one might think initially that all ionizing radiation should produce the same biologic damage. This, however, is not so. When what we traditionally call x-rays (energies from a few 10s of eV to a few hundred keV) interact with an absorber, whether it is a gas, liq...
متن کاملMonte Carlo track simulations
Monte Carlo track structure simulations follow the primary as well as all produced secondary particles event-by-event, from starting or ejection energy down to total stopping. Simulation codes require both transport models and reliable interaction cross sections for the primary and secondary particles with the material under consideration. In general, charged particles can scatter elastically (...
متن کاملElectron Reflection in Monte Carlo Simulations with the code GEANT
Target preheat is a significant concern in inertial confinement fusion experiments because, when the temperature of the target becomes too large, the areal density (density times radius) required for ignition cannot be attained. The majority of preheat comes from fast electrons produced when the laser interacts with the target. When these energetic electrons are slowed by collisions, they relea...
