Everything around us consists of very small particles, namely atoms. The nucleus of each atom strives for stability, but this is possible only with a certain location of protons and neutrons. A nucleus with an inappropriate combination of protons and neutrons may decay or decay in some way. This process is called radioactivity or radioactive decay.
During radioactive decay, the nucleus emits radiation. It can take the form of small, fast-moving particles or high-energy electromagnetic waves emanating from the nucleus. It is this radiation that can cause disease.
All radium atoms are unstable and radioactive. Most of these isotopes decay very quickly, but the most common isotope, Ra-226, decays the slowest. For example, it takes 1,600 years for half of it to decay.
Other elements that do not have stable isotopes in nature are technetium, polonium, actinium and uranium.
Nuclear radiation resulting from the decay of radium and other elements can damage cells in the human body. It can cause cancer and other health problems. Moreover, this can be both short-term strong irradiation and long-term small irradiation.
In this case, scientists can monitor radioactivity and use it to diagnose and treat diseases. Including cancer.
