Understanding Areas about Radonova Laboratories

Nevertheless, granite products that contain naturally occurring radiation are not to be tested except in large group of Canadians with the World Health Organization values that are set as acceptable for humans to live with. Radonova Laboratories┬áis one of the authority sites on this topic. The truth of the matter is that granite is a safe and suitable product. It is commonly used throughout the world, for thousands of years and many studies have been done about its relationship to radiation. Granite is a safe rock. Researchers have developed mathematical models that show that, given the right conditions, one can be exposed to very low levels of granite for an entire year (even more than a year) while still being within safe levels of the stone’s associated health risks.

Based on calculations, it will be noted that, if an average countertop traps an average uranium concentration of four ppm, then the concentration of radon that is given off by the countertop into the household air would be 270,000 times less than the level of radon in the outside air. The maximum contact level that you would receive over one year if you were to sit on a countertop all of the time would be about one quarter of the annual radiation from all sources.It’s important to note that as a building material, granite does allow or allow trace amounts of radon through it that might be in the air, meaning you should be careful with how you work with granite and how long you keep it out. In addition to uranium, small quantities of uranium are found in trace minerals such as biotite in natural stones such as marble. When quarried if a large cluster of biotite is exposed the result initially would be a radon reading. However, once a piece of granite or a natural stone exposed to a large amount of uranium rich mineral in the ground is removed from the source and then exposed to the air, the radon vapour transmission would weaken drastically and then dissipate.
