What is Radon?
Radon is an odorless, colorless, tasteless, naturally occurring radioactive gas that comes up from the ground, most easily released by granite, cement, gypsum, etc. It can accumulate to unsafe levels in the home, especially in the basement, garage and cellar. Every home needs a radon detector.
What Are the Dangers of Radon?
Radon can be inhaled into the lungs, damaging human health. Expert research shows that radon is the most important factor causing lung cancer apart from smoking, and the World Health Organization has listed radon as one of the 19 major environmental carcinogens.
Should you measure radon when you buy or sell your home?

I’m very happy with this radon detector. I had extremely high radon in my basement and now I can use this monitor on a regular basis to keep track of radon levels. It gives me good peace of mind.

It's nice to be able a see in numbers the invisible. Keeps you posted by numbers , your Radion intensity so you can take advasive Acton to lower the radation factor .

This product initially worked fine, but then even after changing batteries, it produces inaccurate readings.Product is only a few months old.

I know the building it's in as a very small amount of radon in it, and it's registering that but I do not know the ppm so I can't say if it's registering correctly for the amount.As for the ease of use, there is only one button which seems to change the units and that's it. Resetting or taking out the batteries is the only other thing related to it.I would look at it whenever I would walk past it, it was always registering something till about 3 weeks ago. I let it go for a couple of days with no change. I tried to do a reset and a battery removal (but only for a few seconds) with no change. Finally I removed the batteries for about an hour. The next day it was back to registering numbers on the screen. There was no other error codes, just blinking dashes when this happened. If you are doing long term monitoring that you aren't looking into for a while, this could be an issue.

I don't know if it's accurate or not because I have nothing else to compare it to . Shows blinking numbers on it though and they are under 1 so I'm hoping it's accurate

Received quickly and results seem accurate. Noticed an increase in radon when placed near a hole in the concrete floor

UPDATE: I have been using this detector for a couple of months, and it seems to be reliable. I ordered it because several houses in my neighborhood had to have radon mitigation fans installed when they were sold. When I checked my house, the readings in the basement near my open sump pump well were very high: 60 to 80! I installed a sump well cover which lowered the numbers to high single digits. I then installed a radon mitigation fan with 3 inch PVC pipe and I'm down to a long term average of 0.24, with single readings from zero to about 0.4 at the highest. So, the readings from this detector seem to make sense and I have made my house safer.ORIGINAL REVIEW: This is a great device to check radon levels if you're planning on selling your home, or just want peace of mind that the levels are safe. It's super-easy to use. Just insert three AAA batteries, wait about a day for the self calibration and startup process to be completed, and the monitor starts showing radon levels. The display is large and clear, and shows the level detected for the last day, and a running average for the entire time since it was powered on.The unit can either just be placed on a flat surface, or there is also a slot on the back to hang it from a screw or nail in the wall. Overall, it's a great way to keep track of radon levels.
