Is There Radiation In Granite
While radon gas and radiation emission levels attributable to granite are not typically high there are simply too many variables to generalize about the emissions from granite countertops.
Is there radiation in granite. However high levels of radon in the home from all possible sources is a health concern because it can cause lung cancer. After all there are always exceptions to the rule. While there are no radiation exposure standard standards specific to granite counter tops there are two standards that may be referenced in any professional evaluation. It does pay to find out for sure if there are harmful levels of radioactive elements in your granite countertops.
However any radiation present would decrease quickly with increasing distance from the source. However keep in mind that avoiding granite countertops does not mean you avoid radiation or radon gas emissions in your home. The lowdown on granite radiation. Granite is a natural source of radiation like most natural stones.
It is extremely unlikely that radiation from granite countertops would increase annual radiation doses above normal natural background levels. 1 there is general guidance on radiation exposures in buildings and radiation exposure from naturally occurring radioactive materials. Some granite and other natural stones contains trace amounts of uranium. If it emits radon it typically does so at very low levels.
It s not true that all granite countertops emit alarming amounts of radon. Potassium 40 is a radioactive isotope of weak emission and a constituent of alkali feldspar which in turn is a common component of granitic rocks more abundant in alkali feldspar granite and syenites. However in some instances tests have found that granite countertops give off potentially dangerous levels of radiation.
