Recently, an environmental monitoring agency in the capital discovered that the radioactivity of her home was nearly twice as high as the safety standard when she tested the product for a consumer Miss Wang. However, the radioactivity of decorative materials such as walls and floors did not exceed the standard. Later, after careful examination and analysis by experts, he found a high-fidelity "genuine murderer" -- a piece of sheep skull art for decoration. No one thought that home accessories could also become a hidden danger in the indoor environment. According to Wu Huishan, an expert from the Engineering Society of the China Association for Science and Technology, nuclear radiation is ubiquitous in life, but radiation doses exceeding safety limits can cause damage to the human body. In addition to granite and other commonly used building materials in the living room may generate strong nuclear radiation, home furnishings of fossils, jade accessories, stone carvings, etc. may produce nuclear radiation, consumers should pay attention.

"Nuclear radiation" is omnipresent <br> In fact, people do not have to talk about nuclear radiation, that is, discoloration, because it exists in all substances, including the water we drink and the air we breathe. This is an objective reality that has been formed for hundreds of millions of years. Also known as "background radiation." We need to understand which nuclear radiation in life is higher than the normal range and we need to take measures to prevent it.
Bone art has not been identified yet <br> According to reports, Miss Wang's art made from bones of domestic animals, and the radioactive content of another bovine bone ornament, and the vertebrae of some "unknown" animals found during the tests There is high nuclear radiation. Since these decorations are mostly purchased from street vendors, it is difficult to ascertain their origin and source. Experts believe that the reason for the high nuclear radiation caused by bone products may be that animals eat certain substances containing uranium, radium, etc., and radium and other substances are deposited on the skeleton to cause high radioactivity. Such bone products should not be placed in bedrooms and children's rooms.
Fossil Radioactivity is under Investigation <br> Fossils are fossils of the geological remains of the geological period preserved by natural action, and chemical fossils of organic matter formed by the decomposition of living organisms. The level of nuclear radiation was found to be high in some tests. Since the composition of the substance has not been detected so far, the cause of high radioactivity has not been found yet.
Stones that conform to Class A national standards can be used indoors <br> According to statistics, currently rock building materials are the main source of nuclear radiation in the indoor environment of high-rise buildings with more than three floors. Among them, granites and ceramic tiles (including blue bricks, red bricks, and various slag bricks) are relatively high, while marbles, diabase, etc. are relatively low in radioactivity. According to national standards, only type A stone can be used indoors.
Jade radioactive low "night pearl" should be used with caution <br> After testing, generally the natural world of gems, including crystal, agate and other radioactivity are not high. Including jadeite, nephrite, and other processing and engraving ornaments, this type of jade made of limestone metamorphism, radioactivity is also very low.
However, the radioactivity of the "Night Pearl" depends on its material composition. According to analysis, at present, there is a part of barite (barium sulphate) in the market that emits light at night after being placed on radium. It has strong radioactivity and is not suitable for indoor use; it is a "fluorite" (calcium fluoride). ) Also known as the "Night Pearl", it is processed and often contains rare earth, barium, and calcium. It is fluorescent when heated and irradiated with ultraviolet light, and it also has different degrees of reflectivity. In addition, some phosphorus-containing minerals can also be Processing into a "night pearl", radioactivity is also high; experts advise that this type of "night pearl" can not be placed indoors, you need to see his radioactive safety certification and the actual test results, when buying and placing must be cautious.
