Tennessee Health departments pass out free radon testing kits

Radon is a gas that is 'naturally occuring' and is common almost everywhere.
Even building codes address it and how to minimize radon leaking into your home through the foundation.

It is said that it is caused by the slow decay of uranium.
However, this should mean that areas in the country that have high concentrations of uranium should also have high levels of radon gas. But that is not so. You can look up the map of radon gas emissions and compare with where uranium mines are found.
It COULD be possible that the wide presence of radon gas is a result of an ancient nuclear war.
Ancient manuscripts seem to tell of nuclear type devices and wide spread devastation.

Just something to think about. I am not saying that this is the cause, just providing some food for thought.

If your home test results are "high," government officials will recommend a "friend" (relative) to lower the levels at a great cost (+ kickback to gov. employee and politician). An old government kickback scam.
