Uses of radioisotopes in radiocarbon dating


Radioisotopes have the supreme advantage that they can be taken to the site when an examination is required – and no power is needed.However, they cannot be simply turned off, and so must be properly shielded both when in use and at other times.The attributes of naturally decaying atoms, known as radioisotopes, give rise to their multiple applications across many aspects of modern day life (see also information paper on The Many Uses of Nuclear Technology).Radioisotopes are used by manufacturers as tracers to monitor fluid flow and filtration, detect leaks, and gauge engine wear and corrosion of process equipment.Both Japan and Malaysia have since backed an IAEA initiative to use NDT for the inspection of civil structures more widely following natural disasters.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.



They are particularly useful where process optimization can bring material benefits, such as in the transport of sediments.The gamma rays, like X-rays, pass through the object and create an image on the film.Just as X-rays show a break in a bone, gamma rays show flaws in metal castings or welded joints.The process of gamma radiography, a type of non-destructive testing (NDT), is used to validate the integrity of poured concrete and welds on fluid vessels, pipelines, or critical structural elements.
