Question

What are the various uses of radioactivity in healthcare? What are the future trends in healthcare with respect to the use of radioactivity?

Answer 1

More than one hundred radio-isotopes have been used to assist in a wide variety of diagnostic tests and treatment protocols. The use of radio-isotopes is convenient because they can emit gamma radiation, have a short half-life, and are eliminated from the body shortly after the completion of the diagnostic test or treatment.

Answer 2

well, one of the most important use is when we use it for radiation technique (such as x-ray).
X-ray allow the health workers to quickly determine the potential problem (like the shape of bone fracture)
