Is Nuclear Density Gauge Dangerous

(Density gauges can contain small amounts of radioactive cesium-137 and americium-241

Are nuclear density gauges safe?

Nuclear gauges use radioactive sources to identify the thickness, density or make up of a wide variety of material or surfaces. These gauges, which are safe to use when the proper safety measures are followed, help people build safe buildings, roads, and make reliable products.

How much radiation is in nuclear gauge?

For comparison, studies indicate that for every test (shot) that a gauge operator performs, they are exposed to approximately 1.2 µSv.
