The generating activity will determine if the electron tubes to be transferred to the DLA Disposition Services site contain radioactive material (radioactivity) in amounts less than, equal to, or in excess of the radioactivity, or qualify as unimportant.
Radioactive material in some electron tubes may not be detectable by radiological survey meters and may only be identified by consulting information sources such as MSDS, HMIRS, Federal Logistics Information System (FLIS), and the product manufacturer.
Prior to turn-in, generators will review information available from MSDSs, HMIRS, FLIS, and the product manufacturer to identify any radioactive material contained in an electron tube.
If the amount of radioactive material, or radioactive material qualifies as unimportant quantities, DLA Disposition Services sites will accept accountability but not physical custody.
The DLA Disposition Services site will not accept physical custody of any electron tube containing any level of radioactivity.
The DLA Disposition Services site will not accept physical custody of electron tubes that have non-detectable levels of radiation based on radiological survey meters when conflicting data from MSDSs, HMIRS, FLIS, or the manufacturer indicates there is any amount of radioactive material in the electron tube.
Non-Radioactive Electron Tubes
Following the determination that an electron tube is non-radioactive generating activities need to be aware that electron tubes may still contain hazardous components such as beryllium containing ceramics, lead, cadmium, mercury, and other regulated substances.
The generating activities will determine if the electron tubes to be physically turned in to the DLA Disposition Services site contain any regulated hazardous substances, which are a safety hazard for handling and storage, regulated for transportation or final disposal.
The DLA Disposition Services site will not accept any non-radioactive electron tubes containing hazardous material without a current MSDS or manufacturer’s product statement that identifies the absence or presence of substances potentially regulated for disposal.
DLA Disposition Services sites will only accept physical custody of electron tubes that:
- Do not contain any radioactive materials and have no hazardous components
- Do not contain any radioactive materials and have all regulated hazardous substances properly identified
- The originator of the transfer DTID of a non-radioactive electron tube will state in block 27: "This item does not contain radioactive material at any level or in any quantity."
- The health physicist or RPO will sign the DTID
