Anyone with the requisite knowledge, training and equipment.
This is not necessary as the granite is only a small piece and is in a well ventilated area. You would need several tons of granite to emit enough radon to be concerned about and it would have to be in an enclosed area with little ventilation.
Anyone can purchase radon test kits to check radon levels in their homes. Radon mitigation systems, however, should be installed by trained professionals to ensure proper installation and effectiveness in reducing radon levels.
If you are asking about Radon, there aren't any sypmtoms. You just develop some form of lung cancer. The chances are low, maybe three in 10,000 people exposed per year, and epidemiology can't really separate those cancers from normal cancer occurances unless the number of people studied is huge. Just have a whole house Radon test done and have them put one test kit or meter under a glass or metal bowl to see how much the granite is contributing to the home's radon. If you are asking about heavy metal posioning, look up the various heavy metals on the internet. Arsenic, polonium, beryilium, chromium, and lead are some of the more common toxic heavy metals found in granite. One warning, other than geologists studying average local granites, there has been no research on what is in commercially sold granites. Right now, you can sell any granite regardless of it's toxicity or radiation levels. Sad business. For more info, use the link below. We have more info and experts on this subject than anyone else. You don't really expect the stone industry to study this do you?
Attempting to cheat a radon test is highly dangerous as radon exposure can have serious health consequences. It is not recommended to manipulate or tamper with a radon test in any way. Accurate test results are essential for your safety and the safety of others.
No- you can test for Radon at any time. Radon levels CAN be higher in winter months due to houses being closed up.
The acceptable radon levels in a home are below 4 picocuries per liter (pCi/L). Radon levels can be measured using radon test kits or by hiring a professional to conduct a radon test in the home.
Yes there are numerous different websites you can access to get a radon test kit so you can test your home for any radon leaks that may be there in there.
Radon testing lets you test for radon gas. Radon gas is harmful to your health and cause things such as cancer.

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.
well if it passed nothing.... passing is good. im guessing you mean failed a radon test? they will probably need to install some sort of blowers to expell the radon. I have something like this on my house. (we have high levels of Radon, especially during thunderstorms.
Radon exist in all the world, in air and waters, in rocks and soils, in buildings and tunnels, etc; but radon concentrations are very variable and different.
