If a nuclear gauge is at least 20 years old, what is the proper way to dispose of it?

The proper disposal of a nuclear gauge, especially one that is at least 20 years old, involves specific regulatory and safety considerations because it contains radioactive materials. Simply selling it at a yard sale, throwing it in the garbage, or taking it to a scrap yard does not comply with safety regulations regarding hazardous materials. These actions fail to ensure that the gauge is handled safely or that it does not pose a threat to public health or the environment.

Instead, the correct approach is to follow the protocols set forth by regulatory agencies, which typically require that such devices be returned to the manufacturer or disposed of through an authorized facility that can manage radioactive waste safely. This helps ensure that the radioactive components are properly contained and that the risk of exposure to radiation is minimized, both for individuals handling the device and for the community as a whole.
