It'a not the radon in the basements that cause lung cancer, it's the radon in the lungs!

Dave - you must be very proud of yourself. Congrats!

Default Radon is a multi-billion dollar industry created by the epa

The results of miner studies have been confirmed by experimental animal studies, which show higher rates of lung tumors among rodents exposed to high radon levels.
Radon levels of 4 actually reduce your risk of lung cancer. Radon baselines are skewed and the whole industry was created by the EPA. Scientists the EPA hired debunked the Radon scam and were quickly hushed.. Don't buy into this scam, the testers are in on it as well, give you erroneous test results and offer to install a pump to make dollars.. This is no more than a shady auto mechanic fixing things that aren't broken and taking advantage of people on a false scare.. Radon levels rise from 0 to 4, cancer levels decline, it's an inverse relationship

Well, let's see your studies showing how beneficial Radon is? It was so important you bumped up a nearly 4 year old thread to post this, so you must have them at your fingertips, right?

And there is a good amount of evidence that Radon levels much above 4 do have a negative effect and that's why they set the action level at 4 and not something lower.

And I'll definitely admit that some people who might be shady could try to say readings are higher to push them installing a remediation system in the home. That's why it's a good idea to have someone who doesn't do those installs to do the test and to ask to see the readout from the monitor.

Granite countertops omit radon, the sun will kill you quicker, on and on it seems. Thanks for any replies.
This is an old thread, but since the topic has come up recently, I'll add this:

Our tests are conducted by the inspection service hired by the buyer -- they have specially trained guys that install the test equipment and then retrieve and produce the results. But we have a couple of go-to mitigation specialists if works needs to be done, not the same company. So, no, in our case, I don't see any collusion or conflict of interest.

BTW, we just had a house with a radon level of 47. Second test was 41. Ouch.

And, something interesting: One inspector told us this week that there's a large quarry near here with high levels of radon, but it seems that a lot of the sand that contractors are using (concrete mixing, etc.) are coming from this particular quarry. Oops . . .

While some studies state granite countertops are the #1 source of indoor radon, no studies show this to be a health hazard. Most testing shows low levels of alpha particle emissions.

Studies show levels up to 3x the EPA "maximum" have a beneficial effect on reducing cancer. However, speaking of conflict of interest, the mitigation industry in the US is a $3B a year industry. Follow the money. Decomposition of granitic type rocks is a common source of radon gas. The granite countertops can be a source, but at such a low level as to not be of concern. The gas can enter the home through cracks in the basement or slab foundation. Sealing the cracks will eliminate up to 90% of the gas entry. However, see the first statement. If you test, I believe you should test your home the way you live in it. Don't seal it up, don't turn off the fans, this increases the levels. If the levels are above 10 to 12 pCi/L or above, you may want to consider sealing cracks and installing ceiling fans and retest. If you still have high levels consider the next level of mitigation, typically sub slab depressurization. The higher soil pressures can force gas through the cracks. Sub Slab typical works best with loam or sandy soils, not so well with clay or other compact soils. Try the simple methods first, besides, the ceiling fans are always nice.
