How long do radon monitors last?

On the screen, you will be able to see the Long Terms Average radon levels and the Short Time Average which ranges between 1 and 7 days – the measurements are made in pCi/L (Picocurie per liter air); at the top there's also the battery indicator (the manufacturer says that the batteries should last for about 2 years …

Do radon detectors wear out?

You should look at your warning device on a regular basis to make sure the system is working correctly. Fans may last for five years or more (manufacturer warranties tend not to exceed five years) and may then need to be repaired or replaced.

What can cause false high radon levels?

A short term test is good at measuring your current radon levels, but these levels can fluctuate due to a number of factors, including:

  • Barometric pressure.
  • Temperature/Season.
  • House construction.
  • Rain soaked ground.
  • HVAC system.
  • Improper placement of the device.

How do you test a radon detector?

Set up the testing device to check the air for radon. Depending on the type of test, it may take just a few days or many months to finish the test. Send the device to a lab and wait for the results. If your test results show a radon level of 4 picocuries per liter (pCi/L) or higher, test your home again.

Does radon level fluctuate?

Radon levels are constantly changing – hourly, daily, and seasonal fluctuations are all common. If you have tested multiple times and received back differing results, don't be too alarmed – this is common!

What causes false radon readings?

Conclusion. Many factors can give either a false negative or a false positive when conducting a radon test. High winds, barometric pressures, temperature, rain, and your home's construction all play a role in radon readings.
