Radioactive quackery

Radioactive quackery is quackery that improperly promotes radioactivity as a therapy for illnesses.

Unlike radiotherapy, which is the scientifically sound use of radiation for the destruction of cells (usually cancer cells), quackery pseudo-scientifically promotes involving radioactive substances as a method of healing for cells and tissues.

It was most popular during the early 20th century, after the discovery in 1896 of radioactive decay.
