Closeout Procedures

 

Addition of a Laboratory to a Radioactive Materials Authorization

Note: The form must be submitted and the room added to the authorization prior to moving into the laboratory.

  • Once the room has been added to the authorization, a "Caution Radioactive Materials" sticker should be attached to the door sign. In addition, appropriate postings should be placed in the room (i.e. State of Maryland Department of the Environment Notice to Employees, Radiation Emergency Procedures and Good Radionuclide Lab Practices).

Discontinuation of a Sewer Permit

  • Written notification should be provided to Radiation Safety Office requesting discontinuation

Note:  Email notification will suffice.

  • Cessation of sewer disposal activities is required.
     
    • Please leave the sewer disposal permit and "Assume this Site is Contaminated" sign posted for removal by Radiation Safety personnel.
    • Complete an online sewer disposal log for each authorized site.>
       
  • Radiation Safety Personnel will then perform a closeout inspection to include wipe tests and meter surveys of the sewer disposal sink and will remove

Inactivation without Inventory

  • For long periods of non-use of radioactive material, an authorized user can request for their authorization to become inactive.  Written notification should be provided to Radiation Safety Office requesting inactivation without inventory status.

Note:  Email notification will suffice.

  • Inactive with inventory indicates that all radioactive material will be disposed.
  • If a sewer disposal permit was issued, cessation of their sewer disposal activities is required.
     
    • Please leave the sewer disposal permit and "Assume this Site is Contaminated" sign posted for removal by Radiation Safety personnel.
    • Complete an online sewer disposal log for each authorized site and place in laboratory for Radiation Safety personnel.
       
  • If there is radioactive material in the authorized users possession, the material may be transferred to another authorized user on or off campus or disposed of as radioactive waste.
     
    • The transfer of radioactive material to another authorized user on campus requires pre-approval by the Radiation Safety Office.  A new Radiation Control Number (RCN) and Receipt, Use and Disposal form (RUD) will be assigned to the material for the new user.  The original user will return the existing RUD to the Radiation Safety Office.
    • The transfer of radioactive material off campus also requires pre-approval by the Radiation Safety Office.  Prior to transfer a copy of the receiving institutions radioactive materials license must be obtained.
    • If the remaining isotope is disposed, the corresponding yellow RUD must be returned to the Radiation Safety Office.
       
  • Radiation Safety Personnel must check any equipment that is present in the room and labeled with a "Caution Radioactive Materials" sign prior to removal of stickers.
  • If there is radioactive waste still present in this room, the waste must be disposed.
     
  • Once all radioactive material including waste has been removed from the laboratory, a final contamination survey should be performed.
  • In addition, all film badges and holders should be returned to the Radiation Safety Office.
  • Radiation Safety Personnel will then perform closeout inspection to include wipe tests and meter surveys of the laboratory and will remove all signs and postings.  In addition, an examination of the room to ensure that all radioactive waste and material has been removed will be conducted.
  • Once inactivation is approved, the authorized user will be exempt from monthly wipe test requirements as well as semiannual compliance inspections.

Incoming Personnel

  • Register for and attend Radiation Safety Training.
  • Complete a Radiation Worker Registration Form to obtain dosimetry devices.
  • If requesting approval as an authorized user of radioactive materials, the Basic Research Application must be completed and submitted to the Radiation Safety Office for approval.  Prior to issuance of authorization, investigator must attend a Pre-Authorization Conference with the Radiation Safety Officer.

Relocation/Disposal of Equipment from a
Radioactive Materials Laboratory

  • If there is any equipment in a room that is labeled with a "Caution Radioactive Materials" sign or has been used with Radioactive materials, this equipment may be transferred to another room listed on a radioactive materials authorization, however, if this equipment is to be moved to a lab not authorized for radioactive material work, Radiation Safety Personnel must check this equipment for contamination or the authorized user can submit a Facility Registration form for the addition of the room to their authorization.  If the equipment is to be disposed of or sent for repair, Radiation Safety Personnel must check this equipment for contamination and remove all labels.
  • Radiation Safety Personnel will perform wipe tests and meter surveys of the equipment as well as remove any Caution stickers/signs.
  • There are certain items that require the assistance of Environmental Health & Safety (EHS) personnel prior to relocation and/or disposal and include:

    • Liquid Scintillation Counters
    • Gamma Counters
    • Radiation Producing Machines
    • Lasers
    • Electron Microscopes
    • Irradiators
    • Gas Chromatographs
    • Sealed Sources
    • Survey Meters
    • Items containing lead

Please contact EHS at 6-7055 prior to relocation/disposal of the aforementioned items.

Renovation of a Radioactive Materials Laboratory

Complete Renovation

  • If a sewer disposal permit was issued for the room, cessation of sewer disposal activities is required.
     
    • Please leave the sewer disposal permit and "Assume this Site is Contaminated" sign posted for removal by Radiation Safety personnel.
    • Complete an online sewer disposal log for each authorized site and place in laboratory for Radiation Safety personnel.
  • If there is radioactive material present in this room, the material may be transferred to another room listed on the authorization or disposed of via the radioactive waste.
     
    • If the remaining isotope is disposed, the corresponding yellow RUD must be returned to the Radiation Safety Office.
       
  • If there is any equipment in the room that is labeled with a "Caution Radioactive Materials" sign, this equipment may be transferred to another room listed on the authorization or can be checked by Radiation Safety Personnel for contamination and remove all labels.
  • If there are radioactive waste containers present in this room, the waste may be transferred to another room listed on the authorization or disposed.

Note:  Transfer of empty or partially full waste containers to another room requires prior approval from EHS.  Please contact them at 6-7055.

  • Once all radioactive material including waste has been removed from the laboratory, a final contamination survey should be performed.
  • Radiation Safety Personnel will then perform a closeout inspection to include wipe tests and meter surveys of the laboratory and will remove all signs and postings. In addition, an examination of the room to ensure that all radioactive material and waste has been removed will be conducted. 

Partial Renovation

  • The area in which the renovation will take place should be cleared of all equipment and radioactive material as well as waste.
  • Once all items have been relocated, a contamination survey of the area should be performed.
  • Radiation Safety Personnel will then perform wipe tests and meter surveys of the area. In addition, an examination of the area to be renovated to ensure that all radioactive material and waste has been removed will be conducted.
