Your Granite Countertops Could Be Killing You

granite, countertops, radon, radioactive, radiation, geiger counter, radon test, cancer, lung cancerDemand for granite countertops has increased tenfold over the past decade. As their popularity has grown, so have the types of granite available. And along with increased sales volume and variety, there have been more reports of “hot” or potentially hazardous countertops, particularly among the more exotic varieties from Brazil and Namibia.

Allegations that granite countertops may emit dangerous levels of radon and radiation have been raised periodically over the past decade. Health physicists and radiation experts agree that most granite countertops emit radiation and radon at extremely low levels.

But with increasing regularity in recent months, the EPA has been receiving calls from radon inspectors and concerned homeowners about granite countertops with radiation measurements several times above background levels.



Dr. MercolaDr. Mercola's Comments:

Personally I love the look and feel of natural granite countertops. Many people agree with me as they have become one of the most sought-after upgrades in residential housing over the last decade. And while most granite is perfectly harmless, the majority of the problems appear to be from some of the newer, more exotic varieties of granite. 

I have had some major home renovation done in the last year, and have also moved into a brand new office building, so I actually became aware of this issue when I hired some Bau-Biology consultants to make sure we had a healthy office and home. 

They pointed out to me that I needed to purchase a Geiger counter to measure the actual granite slab I was going to purchase, before I installed it. So I went through many hundreds of slabs to find ones that were low in radiation, and whose colors I found appealing. 

Are Your Granite Countertops Dangerously Radioactive?

I believe it’s safe to say that not all granite emit dangerous levels of radiation, and you’re more likely to have high radon levels in your home due to radon in your water, than due to your spiffy countertops. Luminous watches and smoke detectors are other sources of radon emissions that could be greater than that of your average granite countertop.

However, you won’t know unless you test them.

As described in this New York Times article, some countertops can measure at levels that are 100 times or more above the ambient radon levels.

Especially troublesome are some of the more exotic granite varieties. Higher radon levels have been detected particularly in red, pink and purple granites.

The purpose of bringing this to your attention is not necessarily to have you rip out your installed granite counters, unless they measure very high and you’re near them for a large part of the day. 

The major reason for sharing this information is to allow you to measure any new slabs of granite you plan on installing. 

How To Use a Geiger Counter to Measure Radiation 

The easiest way to measure your countertops for radiation is to use a handheld Geiger counter. The Geiger counter's sensor is a central metal wire anode surrounded by a thin metal tube filled with neon, argon and a halogen gas. It detects radiation by how much the gas inside the tube is ionized. 

They range in price from $150-400 and can be found easily online. Even Amazon.com carries them. 

Here’s a simple step-by-step process on how to use your Geiger counter: 

  1. Turn on your Geiger counter to apply an electrical charge to the anode wire. The counter will click or flash about 10 to 20 times per minute as it detects background radiation.
  2. Pass the sensor, called a Geiger-Mueller tube, over your granite countertop (or any other material you want to evaluate) with the thin mica window facing the material. Radiation from the material, if any, will pass through the window and ionize the gas inside the tube.
  3. Study the readout, whether a needled meter, flashing LED, or audible clicking. If this is higher than the level of the background radiation, then the material is radioactive.
  4. Count the number of clicks or flashes, or read the attached meter, to determine how radioactive your material is.  

Geiger counters cannot accurately measure the presence of radon gas, specifically. To measure radon, you’ll need a radon detector. However, using a Geiger counter to check for radioactive radiation is a much easier and convenient way to ensure that your granite slabs are safe. 

What is Radon? 

Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste. The amount of radon in the air is measured in "picoCuries per liter of air," or pCi/L.  

About 0.4 pCi/L of radon is normally found in the outside air, and the average indoor radon level is estimated to be about 1.3 pCi/L.  

According to the EPA, you should take action any time the radon level in your home (or office, for that matter) is at or above 4 pCi/L, which carries about the same risk for lung cancer as smoking half a pack of cigarettes per day. 

This does not necessarily mean that 4pCi/L is “safe,” however, just as “only” smoking half a pack a day cannot be considered “safe.”  

There really is NO safe level for radiation. Even the EPA admits that lower levels can still pose a health risk, and you may want to take precautions to further reduce the amount of radon in your indoor space, even if it’s at or below 4 pCi/L. 

Radon Causes Lung Cancer – How to Evaluate Your Risk 

Radon is the second-leading cause of lung cancer after smoking in America, and the leading cause of lung cancer among non-smokers, claiming about 20,000 lives annually, according to EPA statistics. 

Your chances of getting lung cancer from radon depend mostly on: 

  • The level of radon in your home
  • The amount of time you spend in your home
  • Whether you are a smoker or have ever smoked

Logically, smokers are far worse off when it comes to radon raising their lung cancer risk as their lungs are already compromised. Children and developing fetuses are also especially vulnerable to radiation, as it can cause other forms of cancer as well.

According to the EPA, if 1,000 smokers were exposed to the “action” radon level of 4 pCi/L over a lifetime, about 62 of them would get lung cancer from the radiation, compared to only about 7 out of 1,000 non-smokers. 



How to Test For Radon

Testing your home for radon is also a simple process, if you want to check for radon specifically -- although you're likely better off just testing for radioactive radiation with a Geiger counter.

There are many low-cost do-it-yourself test kits available, averaging in price from $20 to $30. You can purchase them online at the EPA’s Web site www.epa.gov/radon, from your regional indoor air environment office, or in your local hardware store.

You can also hire a professional to do it for you, which may be a better option if you’re buying or selling a home. If you decide to go that route, contact your state radon office first to obtain a list of qualified testers.

Alternatively, you can contact a private radon proficiency program, or the American Association of Radon Scientists and Technologists, for lists of privately certified radon professionals in your local area.

I prefer a marble counter top.  blue, or green marble.  Maybe even black.  Granite can be unsafe because it can contain minute deposits of Hornblende -- an ore of uranium.

Most 'granite' counter-tops are not actually granite, but some other stone.

My neighbors just got new countertops-they are a quartz composite that mimics granite.  It looks lovely-I am not sure how "green" the resins are in the composite.

On HGTV they had a green home with concrete-composite countertops
(a mix of concrete, recycled glass and recycled paper).  They looked like soapstone and were sealed with safe sealers.

Fondue, anyone?

How come the good Doctor says NO level of radiation is safe, when he's also published articles saying there's plenty of evidence that low level radiation actually improves health & lifespan? Just curious :)

Small levels of almost any kind of irritant are easy for the body to handle. That's what an immune system is for. I guess the trick is defining the word small in each case ...

Thanks Ed!

I think Dr. Mercola should do a little deeper research on this issue, just as he has on most other health issues. Most people have heard both sides of the story when it comes to artificial sweeteners, saturated fats, cholesterol, animal foods, high-carbohydrate diets, toxins in the household, etc, but most people have not heard of the other side of ionizing radiation. Many scientists have, as you mention, have researched this issue in depth and they have discovered correlations of low level radiation with improved health and vitality, and get this: resistance to cancer!

It is not yet a trendy "green" viewpoint, but that might change in the near future. I think part of the problem is that nuclear radiation gets lumped into the same category as electromagnetic radation. And when is comes to the human body, we all know that our electromagnetic fields are easily disrupted by man-made emf, resulting in a host of problems.

The most important contribution that Mercola makes is that he causes you to QUESTION the subject and better yet, do your own research. I, for one, thought he would cite marble's porous nature (unsanitary).  I would choose quartz any day over marble, I don't care WHAT the trend is!

I couldnt agree more with Islander - this day and age is bringing so many 'sponsered' situations, that it is becoming hard to believe anyone anymore.  Consider this article, it is biased, not researched well and doesn't serve any purpose at all.  Besides being misleading, it really goes nowhere.  He is going back and forth throughout the article.

I'm remodeling my kitchen and decided to forgo the granite for a completely different reason - but the reason is still a major health risk - mold.  It may or may not be true, but a friend's brother (he wasn't trying to sell me anything) installs cabinets for a living and he said that nearly every granite countertop that he removes has mold growing underneath it.  The granite is still very porous and needs to be sealed on a regular basis to prevent the moisture from soaking through.  Most people don't keep up with the sealing like they should (I personally wouldn't want to apply some strong toxic chemical to my food prep area on a regular basis).  It's possible that this isn't a problem is other regions but I live in hot and humid Oklahoma and mold is already quite happy here.  I haven't figured out what I'm doing for counters yet, so if anyone has ideas, please let me know.  I'm trying to research all the "green" products but some are so new, there's not enough info out there.  Cheers, Rachael

we had soapstone counters installed in our kitchen. Natural, non-staining, non-porous (unlike granite), only needs occasional application of mineral oil or you can leave it plain to get a natural patina.  It is used in chemistry labs.  It looks like black marble with white veins in it and has a matte finish, not the superpolished look of granite.

I don't believe that radon poses a threat to any one. The entire earths atmosphere contains only 5 pounds of radon. The atmosphere weighs in at 5,500 Trillion tons, making radon the rarest gas.

A pCi/l is equivalent to two atoms disintegrating per minute per liter.

The radon scare is just another industry generated piece of propaganda.

You will not sell much radon detecting equipment when radon poses no threat to man.

The list of industry created myths is pretty long.

This article and Dr. Mercola's comments seem to buy into the "linear, non-threshold" theory of radiation danger, which assumes that if a lot of radiation is dangerous, there is no level of radiation that is safe.  There is however a considerable body of research about "Radiation Hormesis", which has proven that low amounts of radiation actually contribute to our health by stimulating the immune system.  Just exactly how much radiation has a positive effect on health has not yet been difinitively determined.  It may be a good idea to test granite countertops.  However, we should not be too concerned with relatively low amounts of radiation exposure.

I am heartily tired of these fear-mongering headlines. Granite countertops could be emitting radiation...could be hazardous to your health...could be polluting your kitchen... there are a lot of realistic alternatives to the sensational "could be killing you." Let's adopt that Greek ideal of moderation in all things - including headlines.

Does the marble institute profit from the sale of granite counters? I am guessing they might? Why I ask is I recently heard the same reassurances about pesticides from a pesticide company ... so let's look at what they are saying...

If I am reading it correctly, they say above 'MANY do not emit', which reads in between that SOME certainly do, which is what the New York Times above said..  and 'those treated with sealant REDUCE emissions even further' which means that they still emit some.  Can the sealant be cut, broken or wear off, releasing it again?

So, if SOME do emit, it looks like it boils down to if it is worth the risk for something pretty?  Just like the perfect lawn maintained by herbicides/pesticides which is really a toxic dump. There are likely many other countertop options out there that look just as great with no risk attached...time to do some research :)

Thank you Mercola for passing this along! We even looked at granite ourselves but we won't now, just in case. You just assume if something is natural that it is safe from the earth, but as we know, there are still lots of things from the earth that are not safe to be exposed to (uranium etc).

Without people with bullocks like Mercola looking out for us, I think we'd all be goners by now.

The Marble Institute of America wants to reassure the public that granite countertops are safe.

The U.S. Environmental Protection Agency, Consumer Reports and repeated independent studies have shown granite countertops pose no health hazard.

- EPA stated Friday: “EPA has no reliable data to conclude that types of granite used in countertops are significantly increasing indoor radon levels.” (http://iaq.custhelp.com/cgibin/iaq.cfg/php/enduser/std_alp.php)
- University of Akron researchers found no threat. (www.marble-institute.com/industryresources/radontesting_u-akron2008.pdf)

An independent scientific analysis of a variety of studies shows that, accounting for normal airflow in the typical home, radon contributed by granite countertops ranges from 0.01 – 0.02 pCi/L – levels that are 200 to 400 times lower than the EPA guideline of 4 pCi/L.
- By some measures, the amount of radon emitted by a granite countertop is less than one millionth of that already present in household air from other sources. Many granite countertops do not emit radon at all, and those treated with sealant reduce emissions even further.

Radiation accumulates in your tissues. Just because it is "natural" or "background" does not mean it is good for you or safe. And safe compared to what?. Our bodies are much more vunerable these days and what didn't bother people 100 years ago bothers us now. Also the background level of this radon in the air is always increasing because we keep digging it up and it is an out gassing from our tons and tons of nuclear waste. Background radiation in a gas form varies dramatically by the wind and your body can more easily adapt, whereas in a building like your house it will accumulate at higher concentrations and is part of the sick building syndrome. This buildup of radon weakens the immune system by wearing it out due to steady exposure, unlike outdoors. Your best surface for low toxicity and functional beauty is still porcelian tile. Use the 12x12 or 16x16 size to give the elegant counter look instead ot the 1x1 bathroom floor chicklet look and I think you will be quite suprized by the beauty. It is tougher to cut, but that shows its durability. Over all this is the best bet. And no I don't sell the stuff.

If you want to fear radiation, fear what is generated on a continual basis from any source and especially the government projects like Harrp, medical devices. If it is generated by man if is many times more destructive than in nature. Yellow cake Uranium is nothing compared to the Plutonium we make for bombs. It has no measurable amount, no matter how small, that is not deadly. It breaks down in a relatively short period of time into another form of uranium and then again to plutonium. It's half life is over 8 million years. Nuclear power plants are as stupid as you can get for many reasons, however, the dumping of the depleted uranium is a major health hazard we must track and avoid. See the film "none dare call it treason" and get educated.

Check your basements for radon gas, and concrete slab type buildings.  Radon comes from the depletion of uranium and this could be anywhere.  Especially if you live in the western United States.  This survey should be done before buying, or building a house, or anything that people or animals will frequent.

There is no way I would believe anything the EPA has to say about anything as long as they are part and parcel of the bush administration. They'll say anything because they get money from manufacturers etc to say what they want them to say. Their reputation, like many government agencies is shot. How much did The Marble Institute of America pay the EPA to spout their talking points? Until there is change in Washington and people are hired for their experience in the field instead of who they are friends with or how much they gave to bushs' campaign we will continue to be underserved by the EPA, FDA and most sadly FEMA. As to the meat of this article I can think for myself and I know that formica is probably the safest way to go. On the other hand I never do any cutting on my countertops. I repurpose paper grocery bags and lay my flexible plastic cutting sheet on the paper. No muss, no fuss!

The Federal Government has been distributing misinformation and disinformation since the 60's, regardless of the political affiliation or party in "control".  The low level employees are there just to collect the paycheck and for job security and benefits.  

The head of every department in the  Federal Government is a cabinet member.  All cabinet members are appointed not elected.  All the sub lever department heads are also appointed, not elected.  Since 1960, over 60 % of the cabinet members (department heads) have come from one organization, the Counsel of Foreign Relations (CFR).  This group is dedicated to the one world government concept (New World Order) and is not interested in the health or welfare of the people of this country. It has nothing to do with political party affiliation, they control both parties and consider themselves the ruling elite and above the common man, above ethics, and above moral standards.

Don't be deceived, the feds are not here for your protection, only to rule over you.  The differences between the parties today is only superficial.  They are like two rails of a train track, a left rail and a right rail, which appear separate, but the track is headed full steam toward the one world government, a socialists communist or a socialists fascist type of rule, both authoritarian where you are nothing and have no say so.   Nearly all federally elected officials are dupes and wouldn't be there if it weren't for the money it takes to get them elected, and what goes in their pockets behind the scenes.  This money in general does not come from the electorate but vested money interests.  When you control the money or the monetary system you are in complete control.  The monetary system in this country is controlled by the private bank, falsely called the Federal Reserve, which is not Federal and which has no reserve.  Always look for the root of a problem, which normally starts with  oneself.  Check out:
