Why are radioactive isotopes important?

Answer 1

Hydrogen deuterium radioisotopes combine to form D2o, which is used as a heat exchanger or modulator, C-14 for carbon dating, I-131 for cancer treatment, and P32 for fertilization.

Because radioactive isotopes have unique properties that allow scientists to track and study processes that would be difficult or impossible to observe, they are important because they are used in many different fields, including medicine (diagnostic imaging and cancer treatment), industry (testing materials for flaws and tracing processes), agriculture (studying plant growth and pest control), and scientific research (dating fossils and studying the behavior of elements).
