INTRODUCTION A radioisotope is the unstable form of an element that emits radiation, which is easily traceable, and are used in industry to test, trace and measure industrial processes and operations. Measurements can be made without physical contact to the material or product being examined, increasing the envelope of operating environments and decreasing inspection time. Neutrons from a research reactor can interact with atoms in a sample causing the emission of gamma rays which, when analyzed for characteristic energies and intensity, will identify the types and quantities of elements present. They provide new techniques of collecting data but also reduce costs and improve the efficiency of operations. This problem is particularly prevalent in hot, humid countries. Cobalt-60 (5.27 yr): Tritium, H-3 (12.3 yr): Here are the two main uses of radioisotopes in the industry today. <<0155D8EF7B6007419948941A362CC5BF>]>> NIS reactions are particularly useful for elements such as carbon, oxygen, aluminium and silicon, which have low neutron capture cross-sections. zSealed radioactive sources are used in industrial radiography, gauging applications and mineral analysis.

The IAEA estimates that several hundred thousand such gauges are operating in industry worldwide. Some machines which manufacture plastic film use radioisotope gauging with beta particles to measure the thickness of the plastic film. 0000002521 00000 n The gamma rays, like X-rays, pass through the object and create an image on the film. Widely used for gamma sterilisation, industrial radiography, density, and fill height switches. ... mineral and coal industries.A particular application of NIS is where a probe containing a neutron source can be lowered into a bore hole where the radiation is scattered by collisions with surrounding soil. Radioisotopes are also used by industry for gauging (to measure levels of liquid inside containers, for example) or to measure the thickness of materials. TNC occurs immediately after a low-energy neutron is absorbed by a nucleus; NIS takes place instantly when a fast neutron collides with a nucleus. 0000001302 00000 n x�b```a``vc`e`�mb�g@ ~�+st�x�y������h���"wম�*��fq�z�%�P ������t��`A��v�S�`J� K�%��wt0qC Knowledge application - use your knowledge to answer questions about the applications of radioisotopes Additional Learning This lesson will guide you to explore this subject further.
