If contamination is found, it must be cleaned up. No changes in experimental procedures using radioactive materials are to occur without the approval of the principal investigator. Do not take short cuts. Any abnormal occurrence must be reported immediately to the principal investigator, such as spills, significant contamination, equipment failure, loss of radiation dosimeters and unplanned release. It is the responsibility of the worker to clean any contamination or spills that occur in their work area.
Workers are responsible for maintaining security of radioactive materials.
