Radioactivity

Radioactivity is a natural process by which unstable atomic nuclei lose energy by emitting radiation. This phenomenon occurs in certain isotopes of elements, known as radionuclides, which have an excess of energy or mass or are otherwise unstable. As these isotopes decay, they release radiation in the form of particles (such as alpha particles and beta particles) or electromagnetic waves (like gamma rays).

Radioactive quackery refers to the promotion and use of products or treatments that claim to harness the benefits of radioactivity or radioactive materials without scientific backing or safety considerations. Historically, various individuals and companies have marketed radioactive substances, suggesting that they can cure illnesses or improve health, often exploiting the public's fascination and fear around radiation. This quackery can include items like radioactive water, radium-infused tonics, and other dubious health products.
