Question

where in the industrial field is radioactivity used​

Answer 1

Science and industry use radioisotopes in a variety of ways to improve productivity and, in some cases, to gain information that cannot be obtained in any other way.

Sealed radioactive sources are used in industrial radiography, gauging applications, and mineral analysis.

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).
