Write uses of radioactive isotopes in the Industrial field and in medical science?
Industrial field:-
(i) Measurement of thickness, density and level of metal sheets.
(ii) The radioactive substances radium, promethium, tritium with some phosphor are used to make certain objects visible in the dark, for example, the hands of a clock, and certain other objects.
(iii) Internal cracks and voids in cast iron articles and iron solder can be detected with the help of gamma rays.
Medical science:-
(i) Boron-10, iodine-131, cobalt-60 are used in the treatment of brain tumours, while arsenic-74 is used in the detection of small tumours in the body.
(ii) Strontium-89, strontium-90, samarium-153 and radium-223 are used in the treatment of bone cancer.
