Radon Detector

Post by Lovering »

Hello, We built and set up the Radon Detector and have a quick question. The reading on the multimeter is at 9.4 volts. Is this correct? reading the voltage of the battery used in the chamber. Having trouble getting any results from the daughter catcher unit. Please help!!

Hi Lovering,

The project procedure indicates that the voltage should be “a few tens of millivolts” for the detector before any radon collection (see step 13 under Building the Electronics Shielding for the Radon Detector). Your high voltage reading suggests a problem with the circuit. Check to make sure that the detector is wired as described and that all connections are secure.

I hope this helps. Please ask again if you have more questions.

This is an easy way to tell if your radon system is pulling the right amount of air for the type of system you have, also it will help you know if your system is in need of service by one of our technicians. The readout on the manometer should be between 0.5in – 1.75in. In most cases these are acceptable levels indicating, your system is operating correct. When your Radon system is shut off the fluid should rest at zero if it does not then your manometer is low on fluid. It is important to understand that these readouts will indicate if your system is in need of any maintenance and should be serviced.
