Are Nuclear Density Gauges safe?




When I was planning to buy a nuclear density gauge for my lab I go through a lot of forums for comparing price and features. But in the comment section of most forums are flooded with a particular question that is “Are Nuclear density gauges are safe”?


I have done a lot of research on that and found the answer.
The short answer for the question is “Yes it is completely safe”


What is a Nuclear Density Gauge?

Nuclear Density Gauge is a measuring tool that use radioactive sources to identify the thickness, density or makeup of a wide variety of material or surfaces.
Nuclear density gauges can also be used to measure the density of a liquid in a pipe.

Working Of Nuclear Density Gauges.



It is a type of industrial radiography. This working is similar to to the way a medical x-ray uses radiation to produce images inside of your body.
Nuclear gauges measure three main things: thickness, density, and fill level.
Nuclear gauges are either fixed or portable. Fixed nuclear gauges are permanently mounted in a location.



Is It Safe ??




Nuclear gauges have a radioactive source that is covered by a radiation blocking shield. Gauges can contain a gamma, beta or neutron radiation source. It will not harm humans if it is handled properly and use proper safety precautions. “ Safety is the responsibility of every person who works for the company to take reasonable care for the safety of himself and other human beings and the surroundings which may be affected by his acts or omissions” always keep this in your mind


Safety Precautions



  • Do not use broken devices

  • When a gauge is not in use, it should be put in a proper storage place
  • Follow the procedures set out by your manufactures.
  • Gauges containing radioactive sources should be clearly marked as “Radioactive”.
  • Never attempt to repair a damaged gauge or its safety features unless you have been formally trained.
  • Nuclear gauges may only be disposed of in specific locations and should not be treated as ordinary trash.
