Allowable Waste Materials

Carrie Romanchek places scintillation vial waste into a drum for off-site shipment.

Disposal of low-level radioactive waste is governed by regulations promulgated by Colorado and Washington authorities. These regulations restrict the types of materials that may be included in any container that is sent for disposal to the landfill. Each type of waste shows those materials that are allowed and not-allowed.
