Does Shuhuayu have radiation?

Wood agate, also known as agate silicified wood. Silicified wood is also called wood fossil, and the main mineral is silicon dioxide. Silicified wood was formed about1.500 million years ago. Due to the change of the earth's crust, the trunk of ancient trees was buried in the stratum. Because it is in a closed water-deficient environment, wood is not easy to rot. Through the action of the earth's hydrothermal solution (such as volcanic eruption, etc.) ), silica, iron sulfide, calcium carbonate and other substances enter the xylem cells of trees, replacing the original wood components and retaining some original forms of trees. After 100 million years of fossilization, wood fossils have been formed. Most wood fossils are formed by the invasion of silica, so they are also called silicified wood. Silicified wood can be subdivided into protein silicified wood, agate silicified wood and ordinary silicified wood. The main mineral components of protein silicified wood are opal and chalcedony. Mohs hardness is above 7 degrees, and the density can reach 2.2~2.8 g/cm3, which meets the standard of jade. Therefore, some people call this silicified wood tree jade. The main component of agate silicified wood is also silicon dioxide, and its hardness, density and color are exactly the same as those of natural agate jade, so it is called agate silicified wood, or wood agate for short. Silicified wood and agate silicified wood are rare in protein. Geological circles believe that the collision between Eurasia plate and India plate formed a metamorphic belt from Dehong, China, Yunnan, to India via Myanmar, which is rich in precious stones. This area is also the main producing area of tree-shaped jade and wood agate. Agate silicified wood is red, white, gray, yellow, maroon, maroon and green. Silicified wood is of great ornamental value: because silicified wood was produced in ancient times, it came out before human beings, and it was pregnant with magical cultural connotations. The mysterious color of ancient plants is accompanied by beautiful rings, and the bark and branches that keep their original appearance, especially the hard and colorful tree-shaped jade or wood agate, are more attractive to collectors. Some people regard it as a symbol of longevity, auspiciousness and abundance, which is more meaningful to the collection of cultural relics. In addition, silicified wood is a non-renewable natural heritage with limited resources, especially tree-shaped jade, wood agate and other fine silicified wood is a hot commodity for collectors. Is silicified wood radioactive? According to the research of geologists, there is no scientific basis for saying that there is radioactivity. Through the examination of more than ten samples of silicified wood for many years, the results show that silicified wood does not contain any radioactive elements such as rare earth. Therefore, collection and appreciation are safe and reliable. In the boutique room of Shandong Antique City in quancheng road, we saw a piece of wood agate produced in Myanmar and weighing about 700kg. It originated from nature, exquisite workmanship, delicate texture, smooth surface, Mohs hardness of 7, bright colors, more than five colors, the leaves attached to the old trees before petrochemical can be clearly seen. This kind of high-quality agate is really the top grade of silicified wood, which is rare. The beauty of "Shuhuayu", with its charm, texture, shape, grain and color, is becoming the new favorite of stone appreciation, and collectors from all walks of life are also eager for it. The rumor that Shuhuayu produces radiation can't help but make many strange stone lovers in a dilemma. Where to! It is absolutely bragging to say that it is pure natural and radiation-free! General natural gemstones have certain radiation, but at the same time, they also have certain ability to absorb radiation. Tree jade is no exception. Due to the formation of various chemical elements in geological changes, some silicified wood and tree-shaped jade contain inert gas radon produced by the decay of radioactive element radium, which will form radioactive aerosol at room temperature and produce a certain amount of radiation to the surrounding environment. In fact, radiation is a daily experience. Mobile phones and home appliances have electromagnetic radiation, television and radio stations have long and short wave radiation, and decorated houses also have radon radiation. This is a concept of quantity, that is, a small dose has no adverse reaction to the human body, and more will cause harm. The radiation value of Shuhuayu is far lower than the control value in the modern "Graded Control Standard for Radiological Health Protection of Natural Stone Products", that is, radiation is not dangerous to human body. For example, the room is full of Shuhua jade, and its radiation is only one tenth of that of a luxury decoration room. Because it has been close to the surface for a long time (it may be hundreds of thousands of years from the degree of weathering), most of the radioactive elements have evaporated into the air. So even if it has the same radiation as marble and granite when it is produced (of course, it is actually impossible to achieve it), there is not much left now, and the risk factor is definitely smaller than our daily house decoration and marble granite ornaments. It is recorded in the Classic of Materia Medica and Compendium of Materia Medica written by Shennong in ancient China that jade has the functions of "removing middle heat, relieving annoyance, moistening heart and lungs, helping voice and throat, nourishing hair, dredging blood vessels and brightening eyes and ears". As a kind of jadeite silicified wood, "Yu Shuhua" also has the above beneficial health care functions. Therefore, you don't have to be nervous about the radiation of Shuhuayu. If you are not at ease, you can open all the windows at any time and accept the wind blowing from all sides. It is estimated that no amount of radiation will disappear!
