why is radiochemistry important?

Answer 1

importance of radiochemistry is for the characterization of NORM .
The Radiochemistry Group (RG) supports all areas of chemistry involving the use of radioisotopes including:

Medical/Pharmaceutical uses of isotopes in imaging and therapy.
Understanding the behaviour and transport of natural and anthropogenic radionuclides in the environment and application of radionuclides as tracers of natural phenomena.
Understanding (studying) the coordination chemistry of the radioactive elements.
The production, standardisation and use of radioactive isotopes.
Analytical measurement and application of radioisotopes.
Regulating handling and disposal of radioisotopes.
Waste management and remediation of land contaminated by radioactivity.
The use of radionuclides in nuclear energy production.
Safeguards in the non-proliferation of nuclear materials.

Answer 2

it's how we know how processes work. without radiolabeling metabolism and mechanisms would be a giant black box
