Though the chances are slim, your granite countertop may be emitting high levels of radon gas. If you have granite countertops, you may want to test them for radioactivity. The New York Times examines this growing concern and gives resources for those who are concerned...










Does anyone know if this is also a concern with Silestone?

I read this article yesterday too - Maybe finally folks will get over the "need" for stone countertops.

It depends on the granite and what minerals it is composed of. What do you mean 'need' for stone countertops, they are beautiful, come from the Earth and last forever. My plasticky white apartment countertop always stains and chips.

Somuchbetter--
No - Stone countertops don't last forever.
Stone chips and stains - styles and tastes change whether its the stone itself of the fixtures of the house and kitchen surrounding it - and folks end up ripping out stonework as much as they do laminates, solid surfacing, tile and wood.

Jeez, there is nowhere that's safe anymore... This is a timely warning given the push for all things "green" and natural. Just because it's natural doesn't mean it's safe.

There is also radon seeping from the ground, all the time, you can view the radon map here:

I think most people know about radon coming from the ground - that's why we all do radon tests in basements. But it was news to me when I learned about granite countertops - my home inspector mentioned it to me when he was testing our house (before we bought it). He said they were realy "hot" and way over what he considered to be safe levels. I'm still unclear though about whether the problem exists with other types of stone. I'd be interested if anyone knows...

When marketing a product, one expects a bit of hype. The idea is to show that the product is the best over the competitor's line of product. That is the trade of advertisers and the history of marketing. Some tactics used to sell can be humorous or as serious as the competition between manufacturers. Marketing tactics that play on fears of the general public can be a very powerful tool.
In the present day, there's a very popular angle of "green." This is prevalent everywhere in the media. So what happens when you mix a scare tactic under the guise of environmental concern?
Buildclean found the answer to that question. The premise seems of the nonprofit organization seems to be admirable but the fact that the "awareness campaign" that Buildclean is currently using seems to be curiously slanted. In fact, the target seems to be the natural stone industry.
When Sara Selber of BuildClean was asked how she got involved in natural stone and radon, she explained how she was approached by the owner of C&C North America, a company that produces two products â granite and a quartz product called Silestone®â¢.
"C&C North America then recruited a quartz company called Cambria, after they learned quartz was an issue, she further explained that the two companies hired her to test quartz, granite and other surfaces for radon emission. Both companies are testing their products through BuildClean, and they contracted two labs â one in New York and one in Israel.
We have looked all over the C&C website but cannot find any mention of natural stone.
When ask what granites emit radon, Sara Selber said; "Not all granites emit radon or radiation. There are some that clearly do. There are some that absolutely don't. We don't know," she said.
They're being set up as a non-profit, and they're funded with two large donations.
The first is $250,000 from the makers of 'Silestone.' They manufacture quartz countertops, which is a direct competitor to granite. Silestone finance records show that they started out in April of 1998 with a an initial investment of $410K, made there first million in 1998, sales in 2002 was over $70M, and sales in 2006 was well over $260M. it is not hard to see that they have the money to invest $250,000 in a new advertising campaign.
BuildClean is also getting money from Cambria, another quartz manufacturer.
In fact, Cambria's marketing director is on BuildClean's board of directors.
When asked about the funding Sara responds: I don't believe the issue is who our founders are. And I'm not going to have that debate." That answer seems to be clear enough.
In a recent interview Mrs. Selber mentions teaming up with Al Gerhart who has some interest in the granite \radon scare.
Al Gerhart is a carpenter whohappens to own a website called the Solid Surface Alliance .org. He educated himself, regarding materials he works with that may expose him to harmful elements."
Upon further review it seems this "personality" is well known for his view of natural stone. All one has to do is look at the website to get the gist of his viewpoint. Coincidentally, there also seems to be a new business venture for Solid Surface Alliance as the website now sells Geiger counters to detect radiationâ¦
His debates have earned him quite a place online in forums discussing the subject.
After a certain debate on a well known residential forum, a renowned geoscientist in the industry concluded:
"Al attempts to hijack debates by choking the system with verbal diarrhea. The problem appears to be that he has a bit of knowledge about some things but not enough sense and understanding of the subjects. In that debate on the Garden Forum he threw in so many fabrications (plain made up lies) that his credibility just plummeted to zero.
Anyone who operates this way (by including a number of facts to gain an element of credibility in the eyes of a generally uninformed audience, twisting facts deliberately or because of his lack of understanding, and then throwing in a number of lies) does not deserve extended airtime. Many years ago when doing science psychology I still remember my professor giving the advice to his students that you should never engage a nutter in debate. You can never win an argument with such people. I recognized this early in the forum and that is why I would not engage him in "debate".
One of his major problems is that he does not know what the numbers mean and how they are derived."
In response to the buildclean tactics, The Marble Institute of America is in the process of doing their own independent study:
"The Marble Institute of America (MIA) is grateful for the preliminary response from the members to the newly established Truth About Granite Fund. Based on this positive response, it's clear that their colleagues share their commitment to protect consumers from needless fear mongering by establishing standards for the testing of granite so consumers can safely and comfortably enjoy the beauty, durability and practicality of this natural stone."
When we asked the MIA why Sara Speer Selber consider The Truth About Granite Fund as a draconian move that is being waged against BuildClean(TM), they simple responded:
"The Truth About Granite Fund was established to help raise funds to develop unbiased, scientific standards for the granite industry, including the testing of granite for radon. No such standards currently exist in the natural stone industry. Previous tests of granite samples have found they are safe. However, the Truth in Granite Fund aims to take advantage of new, advanced scientific instruments that make testing both more practical and more accurate. Our goal is to make sure testing follows consistent protocols, so that future studies are meaningful and based on consistent, approved science â not isolated methodologies or unapproved instruments. Ultimately, our goal is to make sure the granite we sell is safe."
This latest sales tactic received the attention of an independent group called the Natural Stone Restoration Alliance (NSRA). The NSRA saw Radon testing as an added service that their members could provide to the homeowners along with all their other services for natural stone. Josveek Huligar, one of the lead testers and trainer for the NSRA , invited times Members of the Solid Surface Alliance dot org to discuss and provide proof of this threat to the home owners.
The Solid Surface Alliance dot org agreed to provide an alleged radiation producing granite sample that they claim to have in their possession to do independent testing. After an initial agreement between the two groups it seems the Solid Surface Alliance dot org has reneged on the delivery of the alleged material. Mr Huligar was disappointed of the outcome. The NSRA than requested the name of the company that Mr. Gerhart claimed to just have rejected over 10k worth of radon producing granite. When the information was not provided, Huligar ask if he could purchase the next slab that Mr. Gerhart rejected. But for some reason Mr. Gerhart could no longer find a sample for testing. Mr. Huligar went on to say: "All we care about at this point. As for whether are not Stone adds a measurable amount of "radon" in a home, Mr. Gerhart had agreed to come to NY and pick out a hot slab that I would place in my own home after testing my home for radon. Once the granite was installed I would test my home again as described by the EPA and have it tested by someone approved by the EPA. Not only would we do the short and long term test, we would also video tape the whole event, the selection, the creation, the install, and than setting up cameras for anyone to view the stone and meters on the net. I was looking forward to do this, but at this time it appears that Mr. Gerhart has no plans on doing as he said which is a big disappointment."
The NSRA plans to push for this simple test, they feel that the consumers only care about one thing; "whether or not adding granite in your home would significantly change the radon levels in a home". At present, the most prudent consumer should watch the outcome of this debate and make an informed decision, not taken in by a scare tactic by advertisers.

We understand why homeowners would be alarmed by this story, but the Marble Institute of America would like to assure people that research shows granite countertops pose no threat. The U.S. Environmental Protection Agency, Consumer Reports and repeated independent studies have shown granite countertops pose no health hazard.
⢠EPA stated Friday: âEPA has no reliable data to conclude that types of granite used in countertops are significantly increasing indoor radon levels.â (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 â 0.02 pCi/L â 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.

As you are probably very aware, there have been on-going accusations that have been consistently made against natural granite products having the ability to cause cancer, because of the high levels of radon that they have been said to produce. These accusations have been going on for quite a while, and it is time to put them to rest.
Who better to accomplish this, than professionals who strive to ensure the safety, as well as the satisfaction of all customers? The National Stone Restoration Alliance is ready to put accusations to rest. Josveek Huligar, a proud member of the NSRA is willing to conduct a very important test in his own home. This is a test that can ultimately change the world of granite, as we know it.
Huligar plans to have the very slab of granite, which was said to be âhotâ and to have contained radon, installed in his own home. The entire process will be on camera no less, for the entire world to see. Before the slab of granite is to be installed, samples will be taken, and the air will be tested in the home, as described by the EPA, and then sent to be evaluated by AirChek ( www.radon.com ), to check for traces of radon and radiation. When this test is complete, the granite will be installed, and then his home will be tested once again to check the levels of radon and radiation. You can monitor this entire process yourself on a public web cam at www.nsraweb.com
The slab being used for this test has been provided by Mr. Tim Scarlata of Atlantic Granite & Marble ( www.atlanticgranite.com ), located in Rochester N.Y. After searching extensively to find the perfect slab for the test, Scarlata was able to locate two slabs of granite that did in fact produce higher than normal readings of radiation. Atlantic Granite & Marble will also be fabricating and installing the counter top while on video for the public to view.
There have been some individuals who have spent large amounts of money on not only the installation of natural granite in their homes, but then they have turned right around and paid tons more money in having the granite removed because of the scare that has been put on society with the radon issues. Huligar, being in the business of ensuring customer satisfaction and quality, also takes this issue very seriously, because the health and well being of his customers are at stake. He plans to do everything possible to ensure the continued safety and reliability of NSRA customers.
You could certainly be seriously hurt, or even killed if granite were to fall on top of you, but at this time, this is the only way that has been proven to cause harm to anyone.
It is the believed that the radon scare is nothing more than marketing strategies, and it has done exactly what it was intended to do, and that is cause fear of using granite in the general public. Huligar and associates of NSRA do not believe this to be true. However, he knows how important it is for the public to see that he stands behind the good name of The Natural Stone Restoration Alliance and their objective to supply clients with the natural beauty of stone, and that every effort will always be taken to do so in a safe manner. To further put the publics mind at rest, solutions to any unfavorable characteristics have already been found.
This test is vital to the natural stone industry, and Huligar is ready to stand up to the test to prove that granite is not harmful to the general public. People need to be able to see these accusations called upon.
The Natural Stone Restoration Alliance (NSRA) has already done their own research, and released their information that looked at both past and present studies, as well as the marketing strategies used by manufacturers that birthed the scare of radon in the home. The findings of this research are quite simply that levels of radon have no significant difference when granite has been installed in a home.
Do not let yourself fall into the trap of letting unproven fears cost you hundreds of dollars, find out the truth yourself by watching the web cam at Natural Stone Restoration Alliance | Home, and let this door be closed once and for all. Viewers can also comment on the research that is being performed at http://www.nsraweb.com/forums/news-5/live-testing-kitchen-radon-before-granite-9010.html
The set up and testing of the hot slabs starts 9/6/2008 at 10am.
The test will be ending September 8, 2008 @ 6:15

Thanks for waiting. I just got back from Vegas where the people who come up with programs to deal with Radon and Radiation were having a conference and one of the topics was building materials.
I personally spoke to Stanley P. Liebert of CMT Laboratories who denied any direct or indirect correspondence with our Al or the SSA. Mr. Liebert went on to say that the only thing that he is hoping to point out is the fact that 10 out of the 2000 granites emit some radiation. This however, does not directly translate to what we have been reading on the web. That is, if you have a slab that has some traces of radiation it will give off radon with in the next ten generations. Mr. Liebert is also the proud owner of granite as well. He thinks itâs crazy for someone to remove a counter top simply because of one area that may show a reading.
I also had the pleasure of speaking with Erik Listou of Build Responsible, Gary Hodgden of AAIR Professionals, Bill Brodhead of WPB Enterprises Inc, and Shawn Price of Air Chek, Inc. These guys gave me a crash course in radiation and radon while confirming that we had the hottest stone measured to date.
Everyone that I spoke to all had the same conclusion. At this time the radiation from natural stone has no significant bearing on the radon levels in a home. It was also explained and demonstrated that the meters on the market are not the best tools to go hunting for radon coming from natural stone. The areas of a slab can be easily avoided or even removed if deemed necessary.
In the NSRA test kitchen, the numbers before the installation were all very low. All were less than 0.3 pCi/l on the days of testing (about as low as anyone can measure.)
The test kit in the hall was 0.6 pCi/l
The test kit hanging in the door way was 0.8
The test kit hanging from the cabinets was 0.7
And the one we hung 12" over the "hottest" spot was 1.0 pCi/l
This test was done in a way to make sure we got the highest readings possible. We now intend on testing the home as if we were simply testing for radon in the home.
