Are granite countertops radioactive?

Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. These trace concentrations may vary from stone to stone, or even within a single slab of granite.

Is granite dangerously radioactive?

Yes, granite can be slightly radioactive, but the real question is whether it is radioactive enough to pose a danger. The answer to that question is no, it is not dangerous. Granite is not likely to cause anyone harm or significantly contribute to a home's radon levels.

Are granite countertops harmful to your health?

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. Experts agree that most granite countertops emit some radon and even other types of radiation.

How much radiation does granite countertops give off?

As indicated in the write‐up, the average radiation exposure measurement from a granite slab was 20 μR h-1.

Do granite counters emit radiation?

It is possible for any granite sample to contain varying concentrations of uranium and other naturally occurring radioactive elements. These elements can emit radiation and produce radon gas, a source of alpha and beta particles and gamma rays (see www.epa.gov/radiation/radiation-terms-and-units).

Radioactive Granite Countertops

Which granite has highest radon?

Granites that emit the most radon are the ones that contain the most uranium. Radon can be a carcinogen and is therefore a health concern, especially in poorly ventilated indoor spaces.

What is the downside of granite countertops?

Cons for Granite Countertops

Granite countertops are strong and durable as long as it receives sealing each year. If homeowners are lax in their maintenance, the porous granite can suck up oils, juice, and wine, which will be impossible to remove. Bacteria can also harbor inside granite if not sealed properly.

What is the healthiest countertop material?

Topping the list for healthier countertop materials is lead-free (US-made) ceramic tile, followed by solid surface products such as Corian, then engineered quartz and cultured marble.

Is quartz safer than granite?

Although quartz countertops will have less to zero radon, it does not preclude granite as a "less safe" choice in kitchen countertops. Given the radiation naturally encountered through flying, walking around a city, and living your everyday life, it is not significant enough to discourage granite in the household.

Why is granite so radioactive?

Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. These trace concentrations may vary from stone to stone, or even within a single slab of granite.

Is granite safe in the kitchen?

The U.S. Environmental Protection Agency says most granite countertops are safe, adding little to a house's radon level. It depends on the rock that is used, the agency says, recommending that homeowners concerned about radon get their countertops tested."

How do you test for granite radiation?

Although not specifically designed or intended for measuring radon emissions from countertops, do-it-yourself home radon test kits are available through retail outlets and online. If you are concerned about the radon level in your home, purchase a test kit and use as instructed.

Does granite contain arsenic?

Granitic rocks may or may not contain high arsenic source, but do not tend to form favorable chemical conditions to release arsenic into groundwater, probably due to the lack of carbonate minerals.

Are marble countertops radioactive?

Both marble and travertine typically have much lower concentrations of naturally occurring radioactivity than does granite.

Is quartz better than granite?

Quartz is actually harder than granite and thus, more durable. In fact, quartz is nearly indestructible, and because it isn't porous like granite, it's easy to keep your countertops relatively bacteria-free.

Does marble give off radon?

Limestone, soapstone, and marble countertops do not pose a radon concern, according to Kitto. If you have granite countertops and want to test them for radon, place a short-term home radon test kit near the granite and another kit in the basement or lowest usable level of the home.

Is quartz countertop toxic?

As sleek “engineered stone” countertops grow in popularity, safety experts are warning that workers who handle them are at particularly high risk from an old workplace hazard — silica, the mineral tied to silicosis, a debilitating and potentially deadly lung disease.

Can you put hot pans on granite?

The short answer is “yes, but you probably shouldn't.” Because of granite's heat tolerance, you can take a hot pan directly out of the oven and put it directly on your countertop. Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly.

Is quartz harmful to humans?

Quartz, silica, crystalline silica and flint are non-toxic materials having no known adverse health effects from ingestion.

What countertop is least toxic?

Are Corian countertops toxic?

The components of Corian® surfaces are not considered chemical irritants and are rated very low to slightly toxic by inhalation or ingestion. The components of Corian® are bound into the product so there is no exposure from touching or handling the material.

Are new kitchen cabinets toxic?

Many cabinets and countertops are made with materials that emit toxic chemicals like formaldehyde and other volatile organic compounds, or VOCs.

What is better marble or granite?

Hardness and longevity: Granite is comparatively harder and stronger than marble. It is mostly known as the most durable natural stone and compared to marble. It is resistant to heat and can easily withstand hot cookware therefore it is perfect for kitchen tops.

How long do granite counters last?

While tile may be able to endure for 100 years or more, that doesn't take into account the gunk and grime that can accumulate between the tiles. On the other hand, granite and other natural stones can expect a lifespan of 100 years, and maybe more, without worrying about such annoyances.

Can u use Pine Sol on granite?

Dilute ¼ cup of Pine-Sol^® in a gallon of warm water. Wipe down granite with a sponge or mop soaked in the solution. Scrub stubborn stains with full strength Pine-Sol^®. Use a cleaning brush or plastic scrub pad rather than a harsh scouring pad, which can scratch unsealed granite.
