摘要
The distribution of energy deposition density in radiate region and its surrounding areas from γ-rays wassimulated and analyzed for a water-ball model with Geant4 package(Geant4.7.0,2005) developed by CERN (theCenter of European Research of Nucleus). The results show that the distribution depends strongly on the collimatingcondition of radiation beam. A well-collimated beam would reduce radiation effects on surrounding areas.
The distribution of energy deposition density in radiate region and its surrounding areas from y-rays was simulated and analyzed for a water-ball model with Geant4 package （ Geant4.7.0,2005 ） developed by CERN （the Center of European Research of Nucleus）. The results show that the distribution depends strongly on the collimating condition of radiation beam. A well-collimated beam would reduce radiation effects on surrounding areas.
