Marble has no radioactive harm to human body

Marble is a natural stone that has been widely used in construction and interior design for centuries. Recently, however, some misleading information has circulated, suggesting that marble may be radioactive and harmful to human health. To address these concerns, the China Stone Association, the National Stone Quality Supervision and Inspection Center, and the National Stone Standardization Technical Committee have issued an official notice clarifying that marble does not pose any radioactive risk to the human body. According to the notice, all natural marble products are safe for use in both residential and commercial settings. This includes countertops, flooring, and other decorative elements. The statement emphasizes that the stone industry should strictly follow national standards, promote accurate information, and ensure the healthy and sustainable development of the sector. Consumers can confidently choose marble for their home or project without worrying about radiation exposure. The confusion around marble’s safety stems from past misinformation and unfair competition by certain parties. Over the years, false reports claiming that marble is radioactive have led to public fear and even affected its use in kitchens and bathrooms. These misunderstandings have also caused unnecessary delays in trade and inspections. Scientifically speaking, marble is a sedimentary rock primarily composed of carbonate minerals. Its formation process is unrelated to radioactive materials, making it inherently safe. According to measurements under the national standard GB 6566, the levels of radium-226, cesium-232, and potassium-40 in natural marble are far below the limits set for Class A materials, which means they are negligible and pose no threat. Additionally, several key industry standards, such as JC/T 202-2011 and GB/T 19766-2005, do not require testing for radioactivity in marble products. In 2009, the Chinese government removed mandatory radiological inspections for marble and other natural stones, recognizing them as safe for import and export. Earlier building codes mistakenly included marble in radioactive testing requirements, leading to confusion and misinterpretation. However, after expert recommendations and active efforts from the Chinese Stone Association, the Ministry of Housing and Urban-Rural Development revised the relevant standards in 2013. The updated guidelines now clearly state that marble does not need a radioactive test report. In conclusion, marble is a safe, durable, and aesthetically pleasing material that has been proven to be free from radioactive hazards. Consumers can continue to enjoy its beauty and functionality without concern. The industry remains committed to transparency, education, and responsible use of natural stone products.
