1908 saw a boom in the use of radioactive water for therapeutic purposes. The discovery of springs in Oberschlema and Bad Brambach paved the way for the establishment of radium spas, which relied on the healing properties of radium. During the cures, people bathed in radium water, drank cures with radium water, and inhaled radon in emanatoriums. The baths were visited by tens of thousands of people every year, hoping for hormesis.
