Keywords： cyclotron

The accelerators should be properly designed to make the radiation field produced by beam loss ual radiation field.The induced radioactivity in accelerator components is the dominant source of occupational radiation exposure if the accelerator is well shielded.The source of radiation is the beam loss when cyclotron is operating.In this paper,the radiation field for CYCIAE-100 is calculated using Monte Carlo method and the radioactive contamination near stripping foil is studied.A method to reduce the dose equivalent rate of maintenance staff is also given.
