The following information was received from the Commonwealth of
Kentucky via facsimile:
On 3/28/2017 the licensee left a Cs-137 brachytherapy sealed source at [address provided]. On 3/30/2017 the licensee discovered the source was not in its shielded container and immediately determined the location of the source and took steps to retrieve and secure it. This event is actively being investigated by the licensee.
Kentucky Event: KY170003
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.

Note: This device is assigned an
IAEA Category 3 value based on the actual radioactivity of the source, not on the device type. (Reference
IAEA RG-G-1.9)
