ABSTRACT:
The radon collector and bubbler includes a syringe having a hollow barrel with an outlet means at its end and a hollow plunger defining a chamber therein which is insertable within the hollow barrel and axially slidable therein. The hollow plunger has a means for dispersing air within the hollow barrel and a means for sealing the area between the syringe and hollow plunger. A hollow tube is located within the hollow plunger and contains charcoal therein. An inlet means is connected to the hollow tube and places the hollow tube in air flow relationship with an area outside the hollow plunger and syringe. During operation, a liquid to be sampled is suctioned into the syringe through the outlet means. Air is then drawn via the inlet means into the hollow barrel of the syringe and the radon therein is absorbed onto the charcoal within the hollow tube. Air flowing within the hollow tube is dispersed so that it will collect radon from the water to be tested.
