AGREEMENT STATE REPORT - LEAKING SEALED SOURCE

The following information was obtained from the Commonwealth of Massachusetts via email:

"Licensee reported one leaking sealed source (Model A3901-2, S/N P4-892, 6 mCi, Co-57) and one contaminated sealed source (Model A3901-2, S/N P4-898, 6 mCi, Co-57). These were among ten sources received from manufacturer individually wrapped in plastic ziplock bags. Leak test results for the other eight sources indicated that they were free of contamination. Leak test result for SN P4-892 was reported as 5.04 times the 0.005 microCurie wipe test limit and the leak test result for SN P4-898 was reported as 23 percent of the 0.005 microCurie limit. Leak test wipes were taken on 4/10/17 and analyzed on 4/11/17.

"Licensee reported the subject sources were not taken out of their respective bags and did not come into contact with anything other than the leak test swab. Initial survey of the outside of the transport package, and subsequent surveys of gloves worn during the leak testing, work area surfaces, inside the lead pig that contained the plastic bags, and outside the ten individual plastic bags indicated no other contamination present other than the interiors of the two plastic bags containing the two suspect sources and the sources themselves. P4-892 was returned to Eckert and Ziegler for analysis. P4-898 was re-wiped for analysis by licensee's leak testing consultant service.

"Agency [Massachusetts Radiation Control Program] considers this event docket to currently be OPEN."

Event Text

UNACCOUNTED STRONTIUM-90 SOURCES

The U.S. Coast Guard did not properly dispose of Inflight Blade Inspection Systems (IBIS) containing 100 microCurie, Sr-90 sources during the retirement of 72 HH-52 aircrafts from 1987 to 1989 and 50 HH-3 aircrafts from 1990 to 1994. The HH-52 contain 3 canisters and HH-3 contain 5 canisters, each canister contain a 100 microCurie, Sr-90 source. Most canisters were retrieved and returned to the manufacture, General Nucleonics, Inc.

The licensee has notified R1 (Jackson).

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
