The following information was received from the
California Department of Public Health via email:
On 09/13/23, Tesla Corporation contacted [Radiation Health Branch] RHB to report a lost radioactive source. The lost item was a Po-210, 10 mCi source, model P-2021-Z705, serial number A2MK511, shipped to the facility on 10/05/2021. Based on this information, the current activity is approximately 281.12 microcuries. The source was used to blow dust off of auto body panels and prevent static buildup prior to painting. The employees at the shop could not provide an estimate of when the last time the device was used and believe that the device may have been disposed of in the trash. They have placed internal restrictions on sites ordering tools with radioactive sources. Additionally, they have transitioned into using an anti-static tool that does not utilize a radioactive source.
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.
