Radon in water measuring system (Type Aqua Kit)
The measurement of the Radon activity concentration of a water sample is based on the equilibrium state between the Radon air and water activity concentrations which is reached within a sealed system after a certain time. The ratio between the activity concentrations depends only on the temperature of the water sample.
The Radon gas solved in the water sample will be de-gassed by an air bubbling flask. The bubbling flask has to be connected to the Radon monitor to create a closed air loop. The air volume of the system circulates through the loop drawn by the internal pump of the Radon monitor. The small bubbles will transfer the Radon very efficient because of the large resulting surface of the junction between water and air.
