Tonight we are easing into some properly boring science for sleep, starting with why it genuinely sucked to be a radium dial painter, the early days of radiation safety, and how glowing paint became a workplace hazard. In classic Sleepless Scientist style, it is slow, calm, and detail rich, focused on the real chemistry and physics behind radium, radioluminescence, and exposure.

As you drift off, you will hear about the lab practices that seemed normal at the time, what scientists misunderstood about ionizing radiation, and how the first safety standards and dosimetry ideas began to take shape. If you like sleep podcasts, relaxing science narration, and quiet true science stories that still teach you something, this is for you.
