The following information was received from the state of
New York (
NYSDOH) via fax:
Four transmission/reference/calibration sources were shipped out in two separate shipments via [a common carrier] to Eckert & Ziegler on 3/17/2022 under two-day shipping and have been listed as 'delayed' since 3/18/2022. Upon contacting [the common carrier], an incident (No. C-61803614) was opened to attempt to locate the sources as [the common carrier] was unable to locate the two shipments. The licensee formally reported the sources as missing to NYSDOH on 3/28/2022.
The Gd-153 source, (1.27 mCi as of 3/17/22), is deemed a reportable quantity under 20.2201 (a)(1)(ii), as greater than 10 times the Appendix C to Part 20 value (10 microCi), but less than 1000 times. The three other sources (Cobalt-57) fall below the values in Appendix C of 10 CFR 20 and are not reportable under 10 CFR 20.2201.
The licensee is continuing to contact [the common carrier] regarding these sources and keeping NYSDOH updated on the status. NYS is consistently monitoring this situation under Incident No. 1389:
Device Manufacturer: Eckart & Zeigler
Device Model: TBD
Device S/N: S5-864
Source Manufacturer: Eckart & Zeigler
Source Model: TBD
Source S/N: S5-864
Isotope: Gd-153
Activity: 1.27 millicuries on 3/17/2022 (10 mCi assayed on 4/1/2020)
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.
