Do you have radioactive granite in your home countertop?بهسنگ
Ordinary kitchens could look fabulous just with a simple touch of a granite countertop. While granite is found in different regions of Iran, Nehbandan granite is the sure choice if you are after both beauty and quality. The question at hand here is whether this magnificent granite addition to your house could be in any way a cause of high levels of radiation? Did you know at all that radioactive granite are everywhere around us?
What is radon? How can it be harmful?
Radon is the gas that is associated with lung cancer if exposed to people and animals. Radon is emitted from radioactive elements and can be the source of alpha and beta particles and gamma rays which are harmful to the body if they go over the normal amount in terms of the time of exposure and concentration.
When should we be alarmed?
EPA or U.S. Environmental Protection Agency, has indicated that the level of 4 pCi/L radon can make a smoker more prone to lung cancer. They have also shown that the soil beneath your house naturally contains 2 pCi/L or less in most cases. The higher the levels, the more prone one may get to lung cancer relatively. The question arises now that are granite countertops safe?
What does the EPA say?
Stones, in particular, do emit some levels of radiation. Granite blocks, in general, have been known to emit radon. But are the levels high enough to ring the alarm? The truth is that the EPA has concluded that generally, the levels are not in the range for us to become cautious. In fact, the main source of indoor radiation comes from the soil in contact with the basements. It might be a good idea to check the levels out and figure out a way to decrease them, if necessary. However, a radioactive granite slab does not increase the levels above the average rates.
What can we do if the levels are high in our home?
In other words, if you ever think the amount of radiation around your house is higher than what is acceptable, it would be a good idea to reduce the environmental factor. This environmental factor is due to the rocks (ex. granite, etc.) or soil beneath your house. In comparison, a countertop’s possible radon emission is always way lower than your surroundings.
Some studies have shown that typically, you need not worry about the concentration of radioactivity in your eye-catching granite countertop, more than you worry about the other materials used in your house such as the bricks, stone, soil, etc.
If and ever EPA finds any results contrary to what is approved, they will not hesitate to let the public know. In a nutshell, there is no reason to be alarmed at the possible risks. We are exposed to some levels of radiation wherever we are and however, we live. The problem arises when the radon levels are higher than what is approved. Still, we know that for a fact, natural stones such as granite do not go over the limit.
