Uses of radioisotopes carbon dating
Industrial gamma radiography exploits the ability of various types of radiation to penetrate materials to different extents.
Gamma radiography works in much the same way as X-rays screen luggage at airports.
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.
The unique characteristics of gamma radiography have resulted in the technique becoming a crucial tool throughout many industries.
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.
Gamma radiography has found use outside of core industrial applications, with the technique successfully employed following the devastating earthquake in Nepal in April 2015.
The height of the coal in a hopper can be determined by placing high energy gamma sources at various heights along one side with focusing collimators directing beams across the load.
Fixed gauges are typically used in production facilities – mines, mills, oil and gas platforms – as a means of controlling and monitoring quality from a production process.
For example, in the North Sea, fixed nucleonic gauges are sometimes deployed to determine conditions within separator vessels and to monitor residual oil content within separated gas streams.
Detectors placed opposite the sources register the breaking of the beam and hence the level of coal in the hopper.
Such level gauges are among the most common industrial uses of radioisotopes.
