Myths of radon is a 4 part series. This is done by a nuclear physicist. What you will learn is the radon EPA residential limit of 4 parts per billion. If you are work then the limit is 100. A banana has more gamma rays than the EPA limit. Further more the “tools” they use to measure the radon limit in your home isn’t actually measuring radon, but a pseudo method to come up a number. My dollar says this speaker is heavily invested in the Radom mitigation industry since he is advertising for a particular business.

Homes in areas with high levels of radons require a system to meet code. Minnesota was 2009 and newer. I've heard and seen studies that areas with high levels of radon do not have higher levels or lung cancer in nonsmokers.

The Eon Flux reference before 1min got me in. Cool scientist grew up in the 90s with MTV.

The answer to what we are doing wrong is what we are doing right. Go into a house's basement that was built in the 1890s and one build in the 2000s after a rain storm. On average the latter has no water in it. Drainage moves water away from the structure and radon uses it to enter.

Do not confuse kinetic energy with particle size. Alpha particles can be stopped by paper because they are a helium nucleus. They are huge when you compare them to a beta particle(an electron or positron) or a gamma ray (photon of light). They are huge so they cannot pass between molecules and other atoms (easily) but because they have a lot of mass, cannot pass through things easily because they are huge and because they are high energy. They absolutely do leave impact craters on soft objects like perspex. The alpha particle is the wrecking ball of the atomic world. Want to know how powerful alpha particles are? Order a small piece of beryllium metal off of ebay, foil is fine. Then take a wet paper tower and wipe up some dust in your house. Fold the paper towel up, lay it on the beryllium and put it into a plastic baggie. You now have a neutron source. The alpha particles that come off of the decay products in that dust impact the surface of beryllium and produce neutrons. That lowly alpha particle which you said cannot do much at all, has enough power to convert beryllium to carbon-12 and liberate a neutron and a gamma ray.

Alpha particles are "dangerous" not because of their size or their kinetic energy, BUT as regards their kinetic energy they can't do the damage that Goodarzi says they do simply being emitted from a radioactive parent nucleus. MNPD3 is correct, paper will stop an alpha particle, so alpha particles "denting" things is a bit out there, and caused me to cut this Goodarzi off - where he gets alpha particles denting anything is a mystery to me. The "Danger" of an alpha particle is that it is a helium atom minus two electrons, and given how desirous He would be to get those two missing electrons (this has to do with the phenomenal stability of the He atom itself - it's pretty much the most stable element in the Periodic Table, but that's with two electrons, so without two electrons it'd pretty much be a raging atomic bull on a mission to get those two missing electrons) it would steal them from ANYTHING that would lose them, which is in turn going to ionize (give a positive or negative change to) things that normally wouldn't be ionized and that normally we wouldn't want ionized. So an alpha particle emitter embedded in your lungs, or anywhere else in your body, vastly increases the chances that such ionization will induce mutations, in turn vastly increasing the chances of cancer.

You do realize that miners working in underground mines were exposed to concentrations of radon that are tens of millions of times greater than the radon levels you mention as "recommended levels". Those "recommended levels" were established by the EPA using junk science.

In Sweden we have a similar limit of 200 Bq/m3 and a national average of 105 Bq/m3. My own apartment has 150 Bq/m3 and according to the radiation safety authorities, radon causes 500 deaths every year. For comparision, traffic deaths is around 350 per year yet radon is largely unknown by the general public. Many buildings were constructed between 1920-1980 using uranium-rich lightweight concrete, most of which are still in use. Last year our elected officials decied to not lower the limit to WHO:s recommended 100 Bq/m3 levels, based on cost. It was considered more cost-effective to let the buildings stand and let people fall pray to cancer. And they call me cynical...

I believe that too much exposure to certain toxins can bring about hypersensitivity. So possibly by weakening and blasting their lungs with cigarette smoke they have perhaps not so much created hypersensitivity as such but more that they have weakened / semi destroyed their lungs already. In this case it might be more due to a build up of destruction rather than a build up of toxins.
