Radioaktívak

Radioaktívak is a term used to describe substances or materials that exhibit radioactivity. Radioactivity is a natural phenomenon whereby the nucleus of an atom becomes unstable and decays, releasing energy and particles. This decay process can be a spontaneous emission of alpha particles, beta particles, or gamma rays. The rate of decay is characterized by the half-life of the radioactive isotope, which is the time it takes for half of the radioactive atoms in a sample to decay.

Materials that are radioaktívak can be naturally occurring, such as certain isotopes of uranium and thorium found in the Earth's crust, or they can be artificially produced in nuclear reactors or particle accelerators. These artificial radioactive isotopes are used in various applications, including medical imaging, cancer therapy, and industrial processes.

The presence of radioaktívak materials can pose health risks due to the ionizing radiation they emit. Exposure to high levels of radiation can damage living cells and increase the risk of developing cancer. Therefore, strict safety regulations and handling procedures are in place for working with or storing radioaktívak substances to minimize exposure and protect human health and the environment. The study and management of radioaktívak materials fall under the field of radiochemistry and nuclear physics.
