Granite is the most abundant type of natural stone in the world.
Is all granite radioactive.
It does pay to find out for sure if there are harmful levels of radioactive elements in your granite countertops.
These radioactive elements are solids but over time they may decay into radon says the environmental protection agency epa.
It is relieving to hear that the radioactive levels in granite and marble are too small to be of any concern but all construction materials in general emit a small amount of radon gas which is radioactive and can easily accumulate in poorly ventilated buildings.
Granite is a natural source of radiation like most natural stones.
Granite contains radioactive materials.
Radon is a radioactive gas that is naturally found in granite due to the decay of radium to radon.
Radon is an odorless colorless gas produced by the breakdown of uranium that seeps out of the earth more commonly in some places on the planet than others.
These trace concentrations may vary from stone to stone or even within a single slab of granite.
The lowdown on granite radiation.
After all there are always exceptions to the rule.
Granite like any other stone may contain veins of naturally occurring radioactive elements like uranium thorium and their radioactive decay products.
In addition many fertilizers and soils are also radioactive as are the fruits and vegetables grown with those fertilizers and in those soils.
However high levels of radon in the home from all possible sources is a health concern because it can cause lung cancer.
However keep in mind that avoiding granite countertops does not mean you avoid radiation or radon gas emissions in your home.
On our planet we are surrounded by radiation from the sun machines airplanes the.
The story here appears to be that some granite countertops have been found to emit high levels of radon a strongly carcinogenic natural radioactive element.
It forms as a result of magma cooling over millions of years under intense pressure and heat.
However it is undeniable that granite does contain radioactive materials some more so than others do.
Inhaling the accumulated radon could give rise to small degree of radiation.
Like all rocks granite may contain naturally occurring radioactive elements like radium uranium and thorium.
Some pieces of granite may contain more of these elements than others.
Granites can contain parts per billion of radium providing for an extremely small amount of.
