摘要

In the study of accelerator driven systems(ADS),which are capable of transmutation of minor actinides and long-lived fission products[1],activation and radiation exposure analyses are among the most important aspects for radiation safety and protection of ADS,especially for the spallation targets.When spallation targets are irradiated by protons,hundreds of radioactive residues are produced.To estimate the possible radiation exposure,one common way is to simulate photon fluence at a given position using Monte Carlo simulation code,then calculate the effective does by applying fluence-to-dose conversion coefficient provided by the International Commission on Radiological Protection publications[2].
