Instead of the bulky machine needed to produce X-rays, all that is needed to produce effective gamma rays is a small pellet of radioactive material in a sealed titanium capsule.The capsule is placed on one side of the object being screened, and some photographic film is placed on the other side.Density gauges are used where automatic control of a liquid, powder, or solid is important, for example as in detergent manufacture.Radioisotope instruments have three advantages: There are two broad types of nucleonic gauges used in industry: fixed and portable.Small concentrations of short-lived isotopes can be detected whilst no residues remain in the environment.By adding small amounts of radioactive substances to materials used in various processes it is possible to study the mixing and flow rates of a wide range of materials, including liquids, powders, and gases and to locate leaks.Radiotracers are used widely in industry to investigate processes and highlight the causes of inefficiency.They are particularly useful where process optimization can bring material benefits, such as in the transport of sediments.

Gauges containing radioactive (usually gamma) sources are in wide use in all industries where levels of gases, liquids, and solids must be checked.The technique allows critical components to be inspected for internal defects without damage.X-ray sets can be used when electric power is available and the object to be scanned can be taken to the X-ray source and radiographed.There, the radioactive source is remotely exposed and a radiographic image of the weld is produced on the film.This film is later developed and examined for signs of flaws in the weld.
