Radon Emanation Board System


At SNOLAB, we have designed and built a radon emanation counting system to measure the amount of radon (222Rn), which emanates out of materials used in the construction of low-background and rare event search detectors. This system consists of a low-radioactivity acrylic emanation chamber, a radon transfer board, and a ZnS Lucas cell. The intended goal of developing this system at SNOLAB is to measure the radon emanation rate of different samples from our user community and around the globe in order to allow proper selection of materials.

Some features and advantages of the new Radon emanation board system :
  • As few Swagelok components as posible: all tubing is orbital welded (except for traps) for best leak tightness and low emanation;

  • The system consists of two primary traps: Bronze wool and Chromosorb;

  • A robust build and on a frame that has wheels mounted;

  • A radon back flow trap - Vladimir trap to control radon flowing from the pump back to the system.

  • All tubing is 316 seamless stainless steel and electropolished.
