Radiumchema Emanator Apparatus (ca. 1920s) |
|
|
This is a very early radium emanator designed to add radon directly into a drinking glass. To use it, water was poured into the top. Over time, the radon gas produced by the decay of the device's internal radium source (removed from this example) entered and charged the water.
