radioaktivního

Radioaktivní is a Czech adjective meaning radioactive. It describes substances or phenomena associated with radioactivity, the spontaneous emission of radiation from the nucleus of an atom. This radiation can include alpha particles, beta particles, and gamma rays, which are forms of energy or particles released as an unstable atomic nucleus transforms into a more stable state.

The concept of radioactivity was discovered by Henri Becquerel in 1896 and further explored by Marie and Pierre Curie. Radioactive materials have various applications, including in medicine for diagnostic imaging and cancer treatment, in industry for sterilization and measurement, and in scientific research. However, exposure to high levels of radioactivity can be harmful to living organisms, potentially causing cell damage and increasing the risk of cancer. Therefore, strict safety protocols are in place for handling and managing radioactive substances. The term radioaktivní is used in Czech to refer to all these aspects of radioactivity, from the physical process to its applications and associated risks.
