Here is a link for several studies from all over the world.
Is there radiation in marble.
There are no radionuclides that could be a source of radiation in these marbles and to mention any radiation in these stones is completely impossible.
Both granite and marble are naturally occurring materials that were formed millions of years ago similar to minerals.
How much radiation exposure can i get from building materials.
However keep in mind that avoiding granite countertops does not mean you avoid radiation or radon gas emissions in your home.
There is still the issue of the rising number of reports from both homeowners and radon inspectors of granite slabs going significantly beyond acceptable levels of radiation to the epa recently.
After all there are always exceptions to the rule.
Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.
While radon gas and radiation emission levels attributable to granite are not typically high there are simply too many variables to generalize about the potential health risks inside a particular home that has granite countertops.
Radiation and radon are generally lower in marbles but both marble and granite has been studied for many years on these issues.
It is believed that this is the result of the introduction of exotic granite slabs into the us.
Granite and marble do emit tiny but noticeable amount of radiation in different proportions.
Therefore the travertine beige marble white and other colored carbonated marbles which make up 95 of turkey s marble production do not have any emission in terms of radiation and.
There are two ways in which countertops tiles and other finishes made of granite might emit any level of radiation.
It does pay to find out for sure if there are harmful levels of radioactive elements in your granite countertops.
Visit the conference of radiation control program directors crcpd exit website to find the radiation program contact for each state.
Marble is commonly used for sculpture and as a building material.
The second is by direct radiation from the surface itself to the homeowner.
The first is by release of tiny amounts of the radioactive gas radon which can be breathed in.
