Although Chadwick doesn’t seem to have recorded the brand it is likely that this was Doramad: a toothpaste mixed with thorium oxide that was supplied to German troops during the First World War. #SocialDistanceLearning #ScienceFromHome #scicomm

And there was also radioactive toothpaste #SocialDistanceLearning #ScienceFromHome #scicomm

You could even wash your hair with Caradium radium shampoo and hair tonics (other brands were available but this is my favourite one). #SocialDistanceLearning #ScienceFromHome #scicomm

You could watch the Pony Ballet dance the Radium Dance wearing their glow in the dark costumes in the musical Piff, Paff, Pouff #SocialDistanceLearning #ScienceFromHome #scicomm

You could spend time seeing atoms decay through your spinthariscope #SocialDistanceLearning #ScienceFromHome #scicomm
