List several uses of radioactive isotopes?

Answer 1

It can be used in medicine, they use a radioactive isotope of a very short half life to help diagnose medical conditions.

Carbon 14 can also be used to date organic material and is determined by the decay rate and comparison of carbon-14 to carbon-12 as carbon-14 is a radioactive isotope and will hence decay at a half life of 5720 years. radioactive isotopes can be used to

determine the ages of rocks and fossils

to treat cancer and kill bacteria that causes food to spoil

as "tracers" to follow the movements of substances within organisms

Answer 2

There are probably three major uses of short-lived radioisotopes. One would be in medical imaging wherein a short-lived radioactive material is given to a patient so that it will "light up" a given type of tissue. Another would be in tracing the movement of compounds in biological investigation. This could be in both animals and plants. Yet a third would be in the treatment (radiation therapy) of certain medical conditions.

Answer 3

1. Medical imaging and treatments, such as in cancer therapy and PET scans.
2. Industrial applications like measuring thickness in materials and detecting leaks in pipelines.
3. Agriculture for studying plant growth and monitoring soil erosion.
4. Environmental monitoring to trace pollutants and study wildlife migration patterns.
