Announcing the New Solid Surface Alliance Forum

For more info, to ask questions, or to find a tester, go to forum.solidsurfacealliance.org

We finially have the Forum up for the Solid Surface Alliance. Unregistered guests can browse all but one of the catagories, but if you want to ask a question or comment, you need to register. Registeration is easy, fill out the usual form, the system will email you with a link to activate your account, then just log in as usual.

The forum is brand new, so there won’t be much content until the membership grows, so add a question or comment if you visit to help get the conversations going. New forums are tough to start, people look around, see little going on, and leave. But, with the volumne of questions we get from the public, this forum will save lots of time and make the answers available for all interested internet viewers to find.

There is one section off limits to all but invited members, that is the Scientific Section which is dedicated for those who are working on the issues. There they can spreak freely, bounce ideas off each other, and not worry about info getting picked up and repeated elsewhere before the proper time.

Please contact us if you have any problems signing up or logging on. Remember you MUST click on the link in the email that is sent to you to activate your account. You might have to scroll down one page when you open the email to find the activation link.

Thanks,
Al

What Information is Available on the Toxic Elements in Granite Countertops?

In addition to the radioactive elements in granite countertops, many of the elements are toxic as well. A wealth of information is available on ATSDR. This link is to the Radium toxicological profile. Click on the individual PDF for more information. There are also short version writen for laypersons that explains the risks in non technical terms.

They had this to say about Radium:

“There is no clear evidence that long-term exposure to radium at the levels that are normally present in the environment (for example, 1 pCi of radium per gram of soil) is likely to result in harmful health effects. However, exposure to higher levels of radium over a long period of time may result in harmful effects including anemia, cataracts, fractured teeth, cancer (especially bone cancer), and death. Some of these effects may take years to develop and are mostly due to gamma radiation. Radium gives off gamma radiation, which can travel fairly long distances through air. Therefore, just being near radium at the high levels that may be found at some hazardous waste sites may be dangerous to your health.”

To put this in perspective, the Houston TV report showed 1,115 pCi/Gram of Radium (adding RA 226 to RA 228) or 1,115 times higher than what is normally present in soil. This report on three hazardous waste sites show comprable levels of Uranuim, Thoruim, Radium and Lead.

At the SLAPS, a site used to store radioactive waste, the gamma exposure rate has been measured at 9 to 261uR/hr, with an average of 84 uR/hr. Some granite countertops are less than 9 uR/hr and the ones that concern us are from 25 uR/hr and up. So basically, this SLAPS hazardous waste site, protected by fencing and warning signs, is about the same gamma exposure that you would get from a higher level granite countertop! These hazardous waste sites have cost millions of dollars to clean up, control ground water and dust from escaping, and will cost millions of dollars to maintain. Yet we allow granite countertops with the same levels of contamination into our homes?

Here is a table showing the amount of contamination in pCi/Grams so you can compare it to the Houston Juparana Bordeaux.
