I am leaving this previous answer up for discussion purposes, to show that a consumer needs to research this topic in depth rather than trust any one side of the issue.
"Marble or Granite countertops are NOT "toxic". Some granites let off a very small amount of radiation that is not harmfull. There is a lot of info on the subject, check out the MIA (Marble Institute of America) they are the national oranization that sets guidelines for all things stone. There is some bad / incorrect info floating around the web that has been put out by producers of "fake" stone materials to promote their own product."
As in any definitive statement, saying that "Marble or Granite countertops are NOT toxic" is not accurate, in fact it is quite missleading. All it takes to disprove the sentence is to find one granite or marlbe countertop that is toxic. Whether it be radiation, Radon, or a toxic heavy metal, it has been proven that "some" granites are a indeed toxic.
"Some granites let off a very small amount of radiation" is partially true, but it avoids telling that some granites do give off large amounts of radiation and Radon. What is important are the unsafe types, since the low radon producers are of little concern.
Depending on the MIA for facts is extrememly irresponsible. A simple Google search, especially using Google Cache, will show that they have been surpressing this information for around 15 years. And they do not set any standards on these issues.
Currently, the MIA's worst nightmare has come true, with the CRCPD (state radiation officials) and AARST (radon scientists) having committees looking into setting maximum allowable radiation/radon levels for stones and measurement protocols. ANSI and ASME are also looking into the controversy for their organizations. In fact, I got an email today from one of the ASME committee members about the issue.
Despite the claims, few countertop shops sell just one product these days. Most sell granite, quartz, solid surface, laminate, and the cement based products, what ever the customers want. For that reason, the facts are begining to become known, to the dismay of those that sell only granite.
Radiation and Radon are generally lower in Marbles, but both marble and granite has been studied for many years on these issues. Here is a link for several studies, from all over the world.

Currently, there are three major U.S. studies on the issue. The radiation issue is being covered by an independent researcher at Rice University, Dr. Llope. Dr. Kitto of the New York State Health Department has recently finished a study on Radon, after reopening it for further results this summmer. The study is in peer review and will be published in a scientific journal. Another expert at St. Johns University, Dr. Steck, is currently studying large amounts of granite slabs.
All three researchers, Llope, Kitto and Steck, have been repeatably quoted in the media saying that there are troubling amounts of Radon and radiation in some types of granite.
We have a Radon test running, over 20 pCi/L from 36 square feet of granite in a 8' x 12' x 8' tall room. That is like smoking 2 1/2 packs a day.

Please respond in the discussion area if you disagree with this position on the issue. If you demonstrate mastery of the subject enough to have a convincing argument on any of my points, I have no problem with further supporting the points with independent data.
What else can I help you with?
What surfaces do you clean with ammonia?
Ammonia is commonly used to clean hard surfaces like glass, countertops, and floors. It is effective in cutting through grease and grime, making it a popular choice for cleaning kitchens and bathrooms. However, it should not be used on certain surfaces like marble or granite, as it can cause damage.
Is a marble pure substance or mixture?
Just like granite, marble is a mixture. However, unlike granite, marble is typically more than 90% calcium carbonate, so it might count as a pure substance. Marble is a type of limestone, so is a mixture.
What is the effect of oven cleaner on kitchen countertops?
Oven cleaner is rather acidic and strong. It should not be used on countertops as it can strip the food grade sealant placed on the material. It can stain, leave harsh residue behind and cause illness if accidentally ingested.
Do granite countertops contain mercury?
Probably not. Normally granite contains no mercury, because of the way it forms. And mercury ore (cinnabar, notably) is distinctly red and not very hard, so even if a granite deposit contained some mercury that part would likely be culled. However, granite can be somewhat porous so if any mercury got into it, say in the finishing process, it could slowly vaporize and be a potential health risk. But again, that seems unlikely. Granite does often contain uranium, and possibly other radioactive elements, which can produce radon gas. This is often a concern with natural stone. From what I understand, the health risks are not well understood.
How effectively does ammonia clean various surfaces and materials?
Ammonia is effective at cleaning various surfaces and materials due to its ability to break down grease and grime. It is commonly used for cleaning glass, countertops, and floors. However, it should be used with caution as it can be harmful if not diluted properly and should not be used on certain surfaces like marble or granite.

What Are the Differences between Marble Countertops and Granite Countertops?
Marble and granite are both popular choices for countertops in kitchens and bathrooms, but they have some key differences in terms of appearance, durability, maintenance, and cost. Here are some of the main differences between marble and granite countertops: Appearance: Marble: Known for its elegant and luxurious appearance, marble typically features veining patterns and a range of colors including white, gray, beige, and other earth tones. It has a softer, more classic look. Granite: Granite tends to have a more speckled or mottled appearance due to its mineral composition. It comes in a wide variety of colors, ranging from light to dark, and may have intricate patterns or flecks of different colors. Durability: Marble: While marble is a relatively durable material, it is softer and more porous than granite, making it more prone to scratching, staining, and etching from acidic substances like lemon juice or vinegar. It requires regular sealing to protect against stains and damage. Granite: Granite is one of the hardest natural stones, making it highly durable and resistant to scratching and heat. It is less porous than marble and is generally more resistant to staining and etching. Granite countertops also require sealing but less frequently than marble. Maintenance: Marble: Marble countertops require regular maintenance to preserve their appearance and prevent staining. They need to be sealed periodically (typically every 6 to 12 months) to protect against moisture and stains. Spills should be wiped up promptly to prevent staining. Granite: Granite countertops are generally easier to maintain than marble. While they also require sealing, the frequency is lower (typically every 1 to 3 years). Routine cleaning with mild soap and water is usually sufficient to keep granite countertops looking their best. Cost: Marble: Marble tends to be more expensive than granite, both in terms of material cost and installation. The price can vary depending on factors such as the rarity of the marble, the quality of the stone, and the complexity of the installation. Granite: Granite is generally more affordable than marble, although the price can still vary depending on factors such as color, pattern, and thickness of the slab. Overall, granite countertops are often more budget-friendly than marble. Ultimately, the choice between marble and granite countertops depends on personal preference, budget, and the specific needs of the space. Both materials offer unique beauty and can enhance the aesthetics of a kitchen or bathroom.
What are alternatives to granite countertops?
Some alternatives to granite countertops include quartz, marble, concrete, wood, and stainless steel. Each material has its own unique characteristics and aesthetics that can complement different kitchen designs. It's recommended to consider the durability, maintenance requirements, and cost of each alternative before making a decision.
Why does everyone think they need granite countertops all of a sudden?

What is the largest span for countertops?
The largest span for countertops without additional support can vary depending on the material and thickness. As a general guideline, for granite or quartz countertops, a span of up to 4 feet may be manageable, but for materials like marble or concrete, spans may need to be shorter to prevent cracking or sagging. It's always best to consult with a professional installer to determine the appropriate span for your specific countertop material.
Other than granite and laminate what are some materials used for kitchen countertops?
Ah, kitchen countertops are like a blank canvas waiting to be filled with creativity!

Where can one price granite countertops online?
One could price granite counter tops online at Home Depot, Menards, Lowe's and Express Countertops. The pricing will vary from store to store so make sure one checks around to get the best pricing available.
Are there any health risks associated with marble countertops?
There are few or no major health risks associated with marble countertops. Marble countertops are an excellent choice with regard to health and safety because the solid marble material doesn't absorb liquid or food juices readily. Marble can also be thoroughly cleaned after each use, reducing the opportunities for bacteria to grow on the surface. Remember, though, that polished marble can be scratched or dulled by abrasive cleansers, so be sure to use only a cleanser specifically intended for use on marble. Marble countertops are porous and susceptible to stains, but they are no potential thread to mans health. No. If sealed with a quality sealer like HMK-S34 Impregnator, this seals the pores of the stone and protects against stains and water damage.
Where could I use marble countertops in my home decor?
Marble is perfect for a bathroom countertop. Marble is a calcium based stone so it is not usually used in a kitchen where acids can etch marble. If you like the old world look of marble kitchen countertops, have your marble "honed" to remove the polish, thus giving you a satin look. Combined with a quality sealer like HMK-S34 Impregnator, marble may be an option for some people. Powder bath counters and master bath vanity tops are very often made out of marble slabs.
