摘要
A design study of radiation shielding due to gas bremsstrahlung is performed for the First Optics Enclosure (FOE). To induce the radiation shower, a copper metal is placed at the entrance of the FOE, followed by a silicon crystal which is set in the middle of the FOE. A lead stop is placed near the lead back wall. To assess the radiation level outside of the FOE, the FOE is encompassed by a water phantom in which the energy deposition is estimated by a Monte Carlo simulation. The dose distributions behind the back, side walls and roof are obtained simultaneously. The average dose equivalent rates are estimated and the FOE radiation shielding wall is examined in detail.
