How do I ship items to SLAC?

Not that this only applies to items that have not been in an accelerator environment and are not activated. Items that require special arrangements such as these should be identified in the safety review process. See the separate FAQ question on shipping activated materials.

​If you are a FACET user, you can send items to the FACET User Manager who will look after the item until it is needed.

Address the shipment to

Christine Clarke
SLAC National Accelerator Laboratory
2575 Sand Hill Road
Menlo Park
CA 94025-7015

If you are shipping from overseas, use our Customs Broker (TIGERS (USA) GLOBAL LOGISTICS, INC.) and leave at least two weeks for the shipment to pass through customs.

How do I ship radioactive material from SLAC?

1) Survey items outside of the accelerator housing with NaI and GM pancake detectors to determine if radioactive or not.  
      (Top of stairs, User trailer)
2) If not radioactive, the Users can prepare e shippers as non - radioactive material or hand carry to their destination.
3) If Radioactive, RP performs a gamma spectroscopy analysis to:
      Determine isotopes and radioactivity.
4) Based on #3 results, RP determines if it is a "Regulated" or Unregulated shipment.
5) Either way RPFO will prepare shipping documents to the receiver.
6) Users supply the receiver's Radiation Safety Office contact phone numbers, address.
7) RP will verify the receiver's radioactive material licenses to have radioactive materials
8) RPFO may assist Users in packaging items.
9) RPFO will take items to Shipping and receiving department for shipment.
10) FACET supplies charge number for shipping costs.
The whole process may take 5 days or so.


How to I ship things out of SLAC?

The Shipping and Receiving website contains instructions. If you don't have a charge number because you are not SLAC staff, ask Christine.


How to I ship items to SLAC that are activated or have been within an accelerator facility?

Radioactive items can be received by SLAC's Radiation Protection department. Even if an item is surveyed to be below background, if it has been in an accelerator facility, it should also be sent to the Radiation Protection department. Standards across labs (and countries) can vary.

Please coordinate through Christine Clarke (cclarke@slac.stanford.edu) to relay the following information and make arrangements:

1) Who owns the device?
2) How long will the device remain at SLAC?
3) What is the radiological nature of the device (surveys, measurements etc.)?
4) Contact name for further questions.

You cannot send radioactive material to SLAC until you get approval from Radiation Protection.
