'f U INADVERTENT SHIPMENT OF A RADIOACTIVE SOURCE NRC INFORMATION'HOTICE NO. 90-56:

i h -IN A CONTAINER-THOUGHT TO BE EMPTY.

All U.S. Nuclect Regulctory Connission (NRC) licensees.

Purpose:

This notice is prc~1ded to inform licensees of a recent transportation incident that could hve resulted in significant radiation exposures ~to workers or

I members of the public. This notice also serves to remind licensees of their responsibilities when importing radioactive materials- or when shipping packages.

1 It is expected that licensees will review this information for applicability to- <

their licensed activities and consider actions, as appropriate, to: avoid j[

! problems when importing radioactive materials or shipping packages. However, .

l 1 suggestions contained in this notice do not constitute any new requirements,-and-no written response is required.

.[

[ Description of Circumstances:

On' March 8,1990, Amersham Corporation (Amersham), Burlington, Massachusetts, an r

NRC licensee authorized to manufacture and. distribute iridium-192 and cobalt-60 sealed sources for use in industrial radiography equipment, received a Model 500-SU source changer from its Korean: product distributor. In accordance with

F shipping. documents, Amersham expected the source changer to be empty. However, j' as an Amersham technician approached the source changer, his audible alarming l dosimeter indicated increased radiation levels. Radiation dose rates measured I as high as 10 rem per hour at approximately 18 inches and 150 rem per hour on contact. Amersham later discovered that the source changer contai .ed a 2.4-curie, iridium-192 source capsule in an unshielded portion of the changer.

Because the source changer was transported cross-country by domestic motor carrier, the potential existed for significant radiation exposure to a variety-

'~

of individuals. A more detailed description of the incident is enclosed in

Attachment 1.

Discussion:

NRC shares regulatory responsibility with the U.S. Department of Transportation s

(DOT) for transportation of radioactive materials. NRC regulations for E1 transportation of radioactive materials are codified in 10 CFR Part 71,

" Packaging and Transportation of Radioactive Material." NRC regulations in 10 CFR 71.0(b) state, in part, "The packaging and transport of licensed mater'ai are also subject ... to the regulations of other agencies (e.g., the U.S.

] Department of Transportation and the U.S. Postal Service) having jurisdiction
