Security and Storage Requirements

RAM security must be maintained at all times. Security violations are frequently cited at institutions utilizing RAM. This type of violation may jeopardize the university's license to use such materials. The Iowa Administrative Code (IAC) specifically addresses security and control of licensed or registered sources of radiation.

Iowa Administrative Code (IAC) 641-40.55(136C) states:

  • The licensee or registrant shall secure licensed or registered radioactive material that is in an unrestricted area from unauthorized removal or access.
  • The licensee or registrant shall maintain constant surveillance and use devices or administrative procedures to prevent unauthorized use of licensed or registered radioactive material that is in an unrestricted area and that is not in storage.
  • The registrant shall secure registered radiation machines from unauthorized removal.
  • The registrant shall use devices or administrative procedures to prevent unauthorized use of registered RPDs.

This means that all RAM (i.e. source material, sealed sources, devices containing sources, labeled materials and even waste) must be in constant attendance by the trained user, or otherwise locked or secured to prevent unauthorized removal or tampering.

Storage of Radioactive Material, Sources, Labeled Materials and Waste

Storage of RAM shall be in secured or locked boxes, cabinets, refrigerators, freezers, waste areas, or rooms unless attended by the licensee. RAM shall be stored in sealed containers in such a way as to prevent accidental release and contamination and to prevent release to the air. If the nuclide requires shielding, it shall be stored in shielded containers in order to reduce exposure to personnel accessing the storage areas. If the radioactive material has been stored in a freezer, the material shall be thawed, opened and handled in a fume hood, glove box or biological safety cabinet.  All containers and contaminated equipment must be marked "radioactive" and indicate the isotope to communicate the presence of material.
