The Radium Emanator (1930-1935) |
|
| This unusual device, approximately 10 inches tall, was manufactured by Radium Life, Inc. of Los Angeles. Like the Thomas Radioactive Cone and the Zimmer Radon Generator, the Radium Emanator was intended to be placed overnight in water so that a ready supply of radioactive water would be available the next day for drinking. It appears to have been made from cement mixed with uranium ore. | |

The device's five-plated design created a large surface area for enhanced emanation. It also allowed the owner to vary the emanating power by adding or removing plates. Initial treatments would probably require the use of all five plates, but, as the cure progressed, the number could be reduced. Size: ca. 7 1/2" high, 5" diameter Exposure Rate: ca. 20 uR/hr above background at one foot The Radium Emanator seems to have been based on a design patented by the same H. R. Zimmer who produced the Zimmer Radium Emanator, later known as the Zimmer Radon Generator. The patent diagram is shown above right (design patent D77452, January 8, 1929). What Zimmer's relationship was with Radium Life, Inc., is not known. Donated by the Illinois Department of Nuclear Safety, courtesy of Sheryl Soderdahl. |
