Radioactive Devices Home

Radioactive materials are present in numerous types of devices used in various medical, commercial, and industrial sectors. These products represent minimal risk to public health during use since the radioactive materials are encased to prevent the escape of radiation. However, if the device is damaged or disassembled, these radioactive sources can potentially contaminate the environment and pose a risk to human health. Therefore, devices containing radioactive material become radioactive sources of concern as they become unwanted, abandoned, lost, stolen, or improperly disposed. The Product Stewardship Institute has explored product stewardship solutions for two types of devices containing radioactive materials: tritium exit signs and fixed nuclear gauges. Fixed nuclear gauges are used to monitor and measure parameters such as density, thickness, and moisture content for industrial applications.
