Radium Toothpaste. Germany. On the back of the product’s tube it stated that ‘radioactive radiation increases the defenses of teeth and gums… cells are loaded with new life energy, the destroying effect of bacteria is hindered… it gently polishes the dental enamel and turns it white and shiny.’
drink radio-active water - ad for 'the revigator', 1920s [uranium-infused crock to make water radioactive before drinking]. I have a blue one in mint condition in its original box. As far as the radium it is not as big a health concern as the heavy metals that leech from the pottery into the water. Therefore, I don't use it.
