Due to my concern about the radiation that granite emits i decided to pursue quartz countertops.
Chinese granite radiation.
Most of the chinese granite recorded the radiation level of 100 millirems that is enough to cause major health issue in humans if they will be exposed to such granite stones.
The chinese granite as most popular natural stone material that play important role at the market.
Chinese granite emits a high level of radiation as its radioactive isotopes contain radium and potassium residues.
In fact we can see it at a lot of famous stone projects around the world some regular customers know this type of material very well but for some new customers we have to introduce with more detailed such as chinese granite radiation and chinese granite price chinese granite use etc.
About the same risk for cancer as smoking a half a.
Some unconfirmed sources state that china export granite with high radiation activity at a cheap price tag to the rest of the world.
But i have become aware that granite comprises quartz.
It is extremely unlikely that radiation from granite countertops would increase annual radiation doses above normal natural background levels.
Sources depict that granite from china is unfit.
So the idea of it having more radiation because chinese stones have more radiation is silly.

Radon that originates in the soil is the main cause of radon problems the epa says.

Ok so the risk from granite is minuscule but how common is radon in u s.

In shanghai china most of the newly built homes have substantial amount of granite items that are found to contain dangerous level of radiation.
On checking with some of the quartz countertop companies i was informed that quartz does contain some radioactive materials.
Recommends taking action if radon gas levels in the home exceeds 4 picocuries per liter of air a measure of radioactive emission.
At issue is whether some granite countertops emit dangerous levels of radiation especially the gas radon which is the second leading cause of lung cancer after smoking.
However any radiation present would decrease quickly with increasing distance from the source.
If you buy it from india it came from brazil.
