One, Does marble emit radiation?
All natural stones, including marble, are radioactive. However, properly processed marble has very low radioactivity, which is lower than that of ordinary wood and glass. This radioactivity poses no threat to human health and can be ignored.
Currently, the market offers marble in three grades (A, B, and C) based on its size and radioactivity. Grade A marble has no restrictions on use; Grade B marble is restricted to use in public areas only; and Grade C marble is only for outdoor use. When selecting, it is important to pay attention to these distinctions.
Two. How long does it take for radiation from marble to disappear?
From an elemental perspective, marble radiation is permanent, with a half-life of up to one thousand six hundred years. However, our lifespan is typically much shorter, meaning that marble radiation will not dissipate. While radiation can have some effects on the human body, the levels are significantly lower than standard levels. Furthermore, many natural substances emit radiation, and the radioactivity of natural marble can be mitigated through proper ventilation. Therefore, you can use marble products with confidence.
Three. Does natural marble pose a health hazard to humans?
The primary radioactive hazards associated with natural stone materials stem from two main sources: electromagnetic radiation originating from within the human body and electromagnetic radiation originating from the external environment.
1、Electromagnetic radiation in the human body
Primarily formed from the radioactive decay of materials in the air, such as radon gas and its byproducts, resulting from the radioactive electromagnetic radiation. Inhalation of radon gas can cause radiation damage and induce lung cancer. Furthermore, radon gas has a high affinity for human body fat, negatively impacting the central nervous system, leading to drowsiness and lethargy.
2、External electromagnetic radiation
This primarily refers to the biological effects produced by the direct exposure of the human body to radiation emitted by natural stone, which can damage the body's hematopoietic organs, central nervous system, reproductive system, and digestive system.
In nature, natural radioactivity exists in marble. When using these materials, it is crucial to ensure they meet national standards. We only need to purchase products that comply with national safety standards. These products are generally rigorously tested, and their radioactivity is minimal, posing no harm to the body.
