The RSC or RSO may require the use of additional monitoring devices when it is felt necessary. Each person assigned a dosimeter shall be responsible for assuring that it is returned to the departmental representative at the pre-arranged date. The RSP will arrange for routine changes of dosimeters, evaluate exposures, and maintain and provide PIs with the records of radiation exposure. Any significant increase in the monthly exposure reading will be investigated to determine probable cause and the appropriate remedial measures to be taken. It is the individual user's responsibility to exchange their film badges with the coordinator.
All film badges are to be exchanged monthly.
It is imperative that this exchange be made promptly at the end of the month to facilitate the legal responsibility to maintain current and accurate radiation dosimetry records. This control will determine the background radiation exposure to the shipment of film badges and will serve to evaluate any exposures to the shipment during transit. The control must be stored away from any radioactive sources and in a cool, dry place. In addition to the monthly exchanges, films can also be exchanged on request by an individual or his group designated person. Only the person who is assigned a film badge shall wear it.
