"On 9/2/08 at 16:30, the [Texas Department of State Health Services] received a letter from the licensee stating that on 8/15/08, they were unable to move the source head on a U.S. Nuclear Model E-0103 Irradiator. The device contains a Cesium (Cs) - 137 source with an estimated activity of 2251 curies and is used in research irradiation of in vitro samples. The source is fully shielded. Dose rates and contamination surveys conducted on the source head were normal. The unit has been taken out of service awaiting repairs."

"The RSO called at 1444 and stated that he had some corrected information. He stated that the device contained two 2660 curie Cs 137 sources installed in 1975 and manufactured on 2/15/68 making the current activity 1045 curies each. He stated that the device had been repaired, but was still trying to find out when."

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT INVOLVING A LOST OR STOLEN TRITIUM EXIT SIGN
The following report was received via email from the State of Washington:
"On August 22, 2008 the department received a report of missing GL radioactive material by a property manager of an apartment building in Seattle, Washington. The device is a Tritium exit sign light module, manufactured by Shield Source Incorporated of Ontario, Canada. Calculations indicate that on August 27, 2008, the source activity was 251 GBq (6.8 curies) of Hydrogen-3. The last known location of the device and radioactive source was in an apartment building located at 1535 Bellevue Ave, Seattle, Washington. The device was discovered missing by the apartment manager's maintenance staff sometime around August 8, 2008. When the maintenance person called an exit sign distributor to order a replacement exit sign, the distributor told the individual to report the missing exit sign to the department.

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.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | |
