The licensee has determined that two food product density
gauges, previously in storage, cannot be accounted for and are considered lost. The density
gauges, installed by Berthold in January, 1992, were last inventoried in April, 2015. They were removed from service in 2008.
An extensive search of the facility was conducted and the devices were not located. It is believed they were sent out as scrap metal. Each gauge contained 30 mCi Cs-137 sources. Their serial numbers are 920-2-92 and 59-1-92.

Following an extensive licensee search of the warehouse, the gauges were found undamaged.

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.
