Science - Radioisotopes

Radioisotopes are used in medicine, industry and for producing energy. Discuss the benefits and disadvantages to society.

A radioisotope is an isotope that is unstable and breaks down. They are used in medicine, industry and for producing energy.
An example of a radioisotope in medicine is Technetium 99. Technetium 99 is used in medical tests, bone scans and for imaging parts of the body. It is used for about 85% of medical procedures that use radioisotopes for treatment of disease and research.
A radioisotope used in industry is Americium 241. This radioisotope is used in most smoke alarms, nuclear batteries and used to determine where to drill for oil. Americium 241 is very useful to humans as it is not harmful when used in, for example, smoke detectors, which save people’s lives.
Uranium 238 is mostly used for producing nuclear energy. It is a good energy source as it doesn’t produce CO₂ and produces minimal waste. Although it is highly dangerous, it is starting to become one of the main energy sources in some countries for example France.
Radioisotopes have many benefits for us in society as we can use them in medicine; for treatment and research, industry; for home products and obtaining oil, and energy; to produce energy in more environmentally friendly ways. Although radioisotopes have many benefits, they also have disadvantages. For example, if radioactive material is exposed to an organism many times, it will have an effect depending on the organism’s resistant strength and the kind of radioisotope released.
Overall radioisotopes are very useful and helpful to us in every way in society.
