Stone News
Since January 1, 2009, the state has cancelled the inspection of radioactive clearance of imported and exported marble and its products. The exempted stones include marble, limestone, travertine, and sandstone, which has won time for the import and export clearance of stone enterprises and reduced the clearance The cost, which marks the clarification of stone's radioactive problems, has achieved initial results. However, due to the monolithic propaganda of some media, the impact of stone's radioactive problems on ordinary people is far from over. In the actual decoration and decoration process, the radioactive problem of stone has always been the object of concern, and some even cause a psychological problem. burden. Still, people are constantly consulting us about the radioactive conditions of stone, and the widespread use of stone is still badly affected.

China's GB6566-2001 "Limits for Radioactive Nuclides in Building Materials", which was implemented on January 1, 2002, stipulated strict internal irradiation and external irradiation indicators for building materials such as cement, brick and tile, sand and gravel. Stone and architectural ceramics represent the interior materials and external radiation indicators and their corresponding scope of application (see Table 1 for specific details). The standard's radioactive requirements for stone materials are looser than the original building material industry standard JC518-1993 (96) "Classification standards for radiological protection of natural stone products". The original GB6566-2000 "Radiation Protection Standard for Key-Building Materials" was used to describe the requirements. The health and safety requirements for stone materials are not high. In 2008, the standard of GB6566-2001 was revised, and all aspects summarized the experience of the implementation of the standard for more than 6 years. Once again, the decoration materials were relaxed. The radiological requirements for plaster and other decoration materials were abolished, and only the requirements for classification of building ceramics, granite, and other decorative materials were proposed, and the classification of granites larger than Class C was abolished because there was no practical significance. The newly revised GB6566 standard was passed at the end of 2008 and was reported for approval. It will be released soon.

From the statistical results of the test data in the table, with the exception of individual species, most of the homemade granite radioactivity belongs to Class A products, and most of them are much lower than the standard indicators, and the radioactive safety factor is large enough. Black granite is generally relatively low, close to the radioactive level of marble. Stones with black mica impurities have a high level of radioactivity and are more common in pink stone; in other color stones, where spots, color lines, or black spots are dense, radioactive levels are higher than normal. Among imported stones, only a few species have high levels of radioactivity. There is also non-uniformity in the radioactive level of stone materials. The level of radioactivity in the same plate is different from that in the appearance of patterns. The radioactivity level varies among different batches of blocks, and the difference in some varieties may be very large. In the statistical tables, granites such as “Red Diamond”, “Brown Beads”, and “Indian Red” have different results for Type A, Type B, Type C, and Type C, which are similar in different batches. There are also other few varieties. My domestic granite has not yet been found to have more than Class C species, most of them are Class A, and individual species are sometimes biased towards Class B.

Stone is an integral part of the physical world, and it is also a source of raw materials for various building materials. Together with other building materials, it forms a space for us to survive. It has been normal and natural for human beings to multiply in a radioactive environment for hundreds of thousands of years and to be constantly radiated by external rays. The radioactivity level of building materials products is low-dose radiation and it is unlikely to cause deterministic effects in the short term. Some reports and rumors are lacking theoretical and practical basis. We should treat the radioactivity problem of granite with a scientific viewpoint, and then we should appropriately and reasonably select stone materials so that we can not only beautify our homes, but also ensure our health and safety.

The radiation damage of building materials to the human body is mainly carried out in two aspects: one is external radiation, mainly gamma ray ionizing radiation; the other is internal radiation, mainly through the inhalation of radioactive gas - helium, releasing α in the body close range Rays break down the cells in the body and destroy the physiological balance, causing damage to the human body. Γ-rays have low energy and strong penetrability. Because humans have a certain immunity to the long-term radiation of the earth, so the external radiation is not very harmful to humans. Many high-irradiation granite mines live for generations. The people did not feel unwell and their life span was not low because they had adapted to this high radiation environment. The original radioactive nuclide 238U becomes radium in the decay process, and radium unstable decays into helium. The thorium continues to decay and emits rays. Radon is a kind of radioactive inert gas that is heavier than air, and it is easy to deposit in the lower part of the house. In an environment that is not ventilated or where people stay for a long time, it is easy to suck into the body and endanger the human body. Internal exposure has the greatest harm to humans. The only way to prevent it is to ventilate the interior and reduce the amount of sucking.

Although the radioactivity standards stipulate strict classification control indicators for granite radioactivity, it does not mean that Class A stone is absolutely safe. Class B stone is absolutely unsafe. There is also a dose of scale; it cannot be said which stone. The species is absolutely green, and which kind of stone is absolutely unsafe, because some granites vary in their mineral composition and they have radioactivity from Class A to Class C. Therefore, in practical use, the batch product should be tested to qualified testing units to determine its exact radioactive content, and then flexible prevention awareness should be adopted according to its use and usage. For example, Class A granites with an internal exposure index of 0.9 must be ventilated for indoor use, and it is advisable not to use indoor rooms that are closed for long periods of time, such as in bedrooms. For small-scale use of Class B stone, for example, the internal radiation index is 1.1. The use of granite as a window sill or tea table board in the bedroom is also not often necessary. Even if the stone with low radioactive level is used, it should also be dealt with in indoor ventilation. The reason is that other building decoration materials such as wall and floor will also emit helium. Another point is that the half-life of radioactive materials contained in building materials is as long as 100 million years. It is a long release process. Unlike formaldehyde, VOC, and other toxic substances in furniture, the volatilization will reduce the concentration and toxicity of radioactive substances. Radioactivity is Forever.

In short, granite radioactivity is not a terrible substance. Correct use and active prevention of the radioactivity of stone and other building materials will make our lives more glorious.
