Radioactive Waste

Definition:   Any waste that contains, or is contaminated with radioactive material.

Examples: Liquid scintillation counting fluids and vials, animal carcasses and excreta, experimental or clean-up materials, and original source vials contaminated with radioactive materials.

Guidelines:

  1. Segregate wastes in appropriate containers according to isotopes and physical form.

  2. Submit waste container for pick up online.

Do not fill the container more than 90 % full.

Do not mix solid material with liquid material inside of jar.

Make sure to identify the type of liquid inside of the jar and constituent percentage. Examples: Water 100%, Biosafe II 100%, (Chloroform 30%/ Phenol 70%),etc.

Liquid Radioactive Waste:

  1. Use a 1 or 5 gallon plastic jar provided by EHS. Ensure that a "Caution Radioactive Material" label is affixed to the outside of the container.

  2. Place the jar in a leak proof container for secondary containment with a "Radioactive Material Log Sheet" attached.

  3. Annotate the nuclide, activity, chemical identification and date of every addition of liquid radioactive waste into the container on the "Radioactive Material Log Sheet".

  4. When the container is full, transfer the nuclide, total activity, chemical identification, and date onto the "Caution Radioactive Material" label on jar.

  5. Fill out the Radioactive Waste Removal Request Form. Submit the form to the EHS.

Do not place any liquid materials inside dry radioactive waste boxes.

Do not place any lead inside dry radioactive waste boxes. Make sure that all source vial containers or pigs do not contain lead and are placed open inside of the box.

Dry or Solid Radioactive Waste:
  1. Place the waste in a 2 ft3 radioactive waste box provided by EHS. The radioactive waste box will be supplied with a "Caution Radioactive Material" label, a "Radioactive Material Log Sheet", and a plastic liner.

  2. Fill the box with only dry, solid radioactive waste.

  3. Annotate the nuclide, activity, and date of every addition of solid radioactive waste into the container on the "Radioactive Material Log Sheet".

  4. When the container is full, transfer the nuclide, total activity, and date onto the "Caution Radioactive Material" label and close the container with filament tape.

  5. Fill out the Radioactive Waste Removal Request Form. Submit the request form to the EHS.

Radioactive "Sharps":
  1. Place in a designated sharps container.

  2. Affix a "Caution Radioactive Material" label to the sharps container.

  3. Fill the container until it is 3/4 full.
  1. Close the container and tape securely.
  1. Fill out the Radioactive Waste Removal Request Form. Submit the request form to the EHS.

It is very important that the type and percent of scintillation fluid be noted on the "Caution Radioactive Material" label and the Radioactive Waste Removal Request Form.

Liquid Scintillation Vials (LSV’s):
  1. Place capped vials in a 5 gallon pail or a 30 gallon drum that is supplied by the EHS with a "Caution Radioactive Material" label, a "Radioactive Material Log Sheet", and a plastic liner.

  2. Fill the container only with liquid scintillation vials no other waste is acceptable in these containers.

  3. If the scintillation cocktail is also a hazardous waste as defined by the Environmental Protection Agency label the container with the words "Hazardous Waste".

  4. Annotate the nuclide, activity, chemical identification (scintillation fluid brand), and date of every addition of LSV’s into the container on the Radioactive Material Log Sheet.

  5. When the container is full, total the "Radioactive Waste Log Sheet", transfer the nuclide, total activity, chemical identification, and date onto the "Caution Radioactive Material" label and close the container.

  6. Fill out the Radioactive Waste Removal Request Form. Submit the request form to the EHS.

Radioactive Animal Bedding and Wastes:
  1. Place in a plastic bag.
  1. Twist the bag at top, bend twisted portion to form a loop and seal loop with filament tape.

  2. Place the bag into a separate bag and repeat step two above.

  3. Affix a "Caution Radioactive Material" label to the outer container.

  4. Make sure the "Caution Radioactive Material" label is filled out properly with the nuclide, total activity, and date.

  5. Fill out the Radioactive Waste Removal Request Form. Submit the request form to the EHS.

Radioactive Animal Carcasses and Tissues:
  1. Place in a clear plastic bag.

  2. Twist the bag at top, bend the twisted portion to form a loop and seal the loop with filament tape.

  3. Place the bag into a separate bag and repeat step two above.

  4. Affix a "Caution Radioactive Material" label to the outer container.

  5. Make sure the "Caution Radioactive Material" label is filled out properly with the nuclide, total activity, and date.

  6. Freeze the bag.

  7. Fill out the Radioactive Waste Removal Request Form. Submit the request form to the EHS.
