Striz Radium Rock (ca. 1930) |
|
|
|
|
| This device belongs to a
category of devices know as emanators that were placed in water, usually 1-2
gallons, to infuse the water with radon, a radioactive gas.
It is very similar in appearance to the Hammer Radium Activator used in the Radium Water Jar. Whether the Striz Radium Rock originally came in a jar, or whether it was a stand alone device such as the Thomas Cone, is not known. As a guess, I would say that the radioactive component, either uranium ore or purified radium, was mixed throughout the matrix of the device. Size: 3.75" diameter, 1.9" high Exposure Rate: 20 uR/hr above background at one foot |
