Radioisotoopit, or radioactive isotopes, are atoms that have an unstable nucleus and are therefore radioactive. Unlike stable isotopes, which are common in nature, radioisotopes decay over time, emitting radiation such as alpha, beta, or gamma particles. This decay process is governed by the principles of nuclear physics and results in the transformation of the atom into a different isotope or element.

Radioisotopes are used in various fields, including medicine, industry, and research. In medicine, they are employed in diagnostic and therapeutic procedures. For example, technetium-99m is used in imaging procedures like SPECT and PET scans, while iodine-131 is used to treat thyroid cancer. In industry, radioisotopes are used in thickness gauges, moisture meters, and level indicators. Research applications include carbon dating, which helps determine the age of ancient artifacts, and tracer studies, which track the movement of substances through biological systems.

The production of radioisotopes typically involves the bombardment of a stable isotope with high-energy particles, such as protons or neutrons, in a particle accelerator or a nuclear reactor. The resulting isotope may be radioactive and can be separated and purified for use.

Radioisotopes pose health and safety risks due to their radiation. Proper handling, storage, and disposal procedures are essential to minimize exposure. Regulations and guidelines, such as those set by the International Atomic Energy Agency (IAEA), ensure the safe use of radioisotopes.

In summary, radioisotopes are valuable tools in various scientific and industrial applications, but their use requires careful consideration of the associated risks.
