Radiation Dose Simulation and Measurement Plan for Ssrf Beam Lines by Using Atom Phantom

Radiation dose assessment in advanced synchrotron radiation facility is challenging due to the complexity and uncertainties of radiation source terms induced by high energy particle accelerator. Shanghai Synchrotron Radiation Facility (SSRF) is the first third-generation synchrotron facility in China, which was completed in 2009. Radiation dose assessment for workers at SSRF Beam lines is highly concerned. This study presents the dose simulation with Monte Carlo method. The dose simulation was performed with a hybrid phantom coupled into MCNPX code. The hybrid phantom was constructed by combining the ATOM phantom and the Voxel-based Chinese Reference female Phantom (VCRP-woman) originally developed by using the high resolution color photographs. The organs absorbed dose calculated for photon and neutron were compared. An Experiment of measuring the organs dose by using the ATOM phantom will be performed in the near future.
