Radon Source [RF series]

Accurate and long term stable sources of defined activity of 222Rn in gas phase. Radon is released from thin layer of a plastic foil with emanation power approaching 1. The source is constructed as a stainless steel cylindrical case supplied on the ends with the two ball valves and the two aerosol filters connected on the output aperture of the valves. All parts are made from stainless steel or Teflon.

 

Application

The sources are designed for laboratory and field conditions. The main application is calibration of devices and detectors for activity measurements of 222Rn and 226Ra for environmental research. The user can apply the source in batch or flow through mode.
