Guidelines for beamline radiation shielding design at the Advanced Photon Source.
Shielding for the APS will be such that the individual worker dose will be ALARA (as low as reasonably achievable) and less than 5 mSv/yr (500 mrem/yr). The APS shielding policy requires that the average worker dose be below 2 mSv/yr (200 mrem/yr). Worker dose is monitored, and frequent area-surveys are performed by health physics personnel. For cases in which surveys indicate elevated hourly dose rates that may impact worker exposure, additional local shielding is provided to reduce the radiation field to an acceptable level. Passive monitors are used throughout the facility to integrate doses in various areas. The results are analyzed for trends of increased doses, and shielding in these areas is evaluated and improved, as appropriate.
