Radioactivity is used in industries in the following ways:
1) Knowing the penetrating power of Beta particles, they are used to control the thickness of paper.
2) Radio isotopes such as Uranium 235 are used as a fuel in atomic energy reactors.
3) The ionising effect of radiations from radioactive isotopes is used in making certain luminescent signs.
4) Radio isotopes are used by engineers in factories to avoid accumulation of charge on moving parts of machines due to friction.....

Uses of radioactive isotopes in the industrial field:
(1) Internal cracks and voids in cast iron articles can be detected with the help of gamma rays.
(2) Isotopes like cobalt-60, irridium-192 are used in the radiography camera.
(3) The radioactive substances radium, promethium, tritium with some phosphorus are used to make the hands of a clock visible at night.
(4) Krypton-85 is used in lamps while promethium-147 is used in portable X-ray units as the source of beta rays.
(5) Luminous colours are used to decorate ceramic tiles, utensils, plates, etc. Earlier uranium oxide was used in the paints.
