Is There Radiation In Granite

However any radiation present would decrease quickly with increasing distance from the source.

Is there radiation in granite.

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. 1 there is general guidance on radiation exposures in buildings and radiation exposure from naturally occurring radioactive materials. 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.

Use the radiation dose calculator to estimate your yearly dose from sources of ionizing radiation. Children and developing fetuses are vulnerable to radiation which can cause other forms of cancer. After all there are always exceptions to the rule. Some granite and other natural stones contains trace amounts of uranium.

However high levels of radon in the home from all possible sources is a health concern because it can cause lung cancer. 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. 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.

The lowdown on granite radiation. However keep in mind that avoiding granite countertops does not mean you avoid radiation or radon gas emissions in your home. At most only a tiny percentage of them have been tested for radon or radiation levels but a recent test of 13 types of granite typically used for countertops found no radon or very low levels of.
