Myanmar wood fossils have a strong texture, moist and delicate, bright and colorful colors, and clear lines like silk. The identity of fossils is a highlight in the collection. Wood fossils have high hardness and are suitable for long-term preservation and will never fade. It is becoming the new favorite of stone appreciation, and collectors from all walks of life are also flocking to it. Rumors about the radiation produced by wood fossils can't help but make many strange stone lovers in a dilemma. Where to!
It is absolutely bragging to say that wood fossils are pure natural and radiation-free! General natural gemstones have certain radiation, but at the same time, they also have certain ability to absorb radiation. Wood fossils are no exception. Due to the formation of various chemical elements in geological changes, some silicified wood and wood fossils 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. It can be said that everything we participate in has a certain radiation dose.
However, the radiation value of wood fossils is far lower than the control value in the modern "Classification Control Standard for Radiological Health Protection of Natural Stone Products", that is, the radiation of wood fossils is not dangerous to human body. For example, the room is full of wood fossils, and its radiation is only one thousandth of that of a luxuriously decorated room. Because wood fossils have been close to the surface for a long time (it may be millions of years from the degree of weathering), most radioactive elements have evaporated into the air. Therefore, even if wood fossils have the same radiation as marble and granite when they are generated (of course, it is actually impossible to achieve wood fossils, and the formation environment of wood fossils is similar to that of jadeite, which is formed under the dynamic metamorphism and does not have the deep environment of contact with radioactive elements), there are few left now, and the risk factor of wood fossils radiation is far less than that of our daily house decoration and marble granite ornaments.
Shennong's Classic of Materia Medica and China's Ancient Compendium of Materia Medica record that jade has the functions of "removing middle heat, relieving annoyance, moistening the heart and lungs, helping to relieve sore throat, nourishing hair, dredging blood vessels and brightening eyes and ears", and the silicified wood-"wood fossil" as jade also has the above beneficial health care functions. So, you don't have to be nervous about the radiation of wood fossils. If you are not at ease, you can always open the windows around and accept the wind blowing from all directions. It is estimated that no amount of wood fossil radiation will disappear without a trace!
Question 2: Does silicified wood have radiation? It is radioactive.
1, silicified wood is a real wood fossil, which was quickly buried millions of years ago and replaced by SiO2 (silicon dioxide) in groundwater. It retains the wood structure and texture of trees. Colors are khaki, light yellow, tan, reddish brown, grayish white, grayish black and so on. The polished surface can be glassy, opaque or slightly transparent.
2. High-quality silicified wood has the beauty of fossils, strange stones and jade. Besides making fossil ornaments, strange stones and jade ornaments, you can also cut and polish silicified wood ornaments, such as beads, rings, pendants and bracelets. It is best to wear this kind of jewelry, which can reflect wood grain or cell structure, and feel the life course of the earth for hundreds of thousands of years, thus enhancing the understanding of the mystery of the earth.
Question 3: Will wood fossils have radiation on human body? First of all, there is no graph. There is definitely radiation, but it is very low, even lower than the background radiation, and will not cause any harm to the human body.
Question 4: Is silicified wood harmful to human body? Basic information silicified wood orders: conifers; Part: unclassified; Common name: conifer; Also known as Mushiyu era: Permian-Holocene; Distribution: all over the world. Origin: Silicified wood can be found everywhere in plants. Note: Silicified wood cannot be associated with specific plants or trees. Silicified wood is mostly coniferous. Silicified wood is very attractive and comes in many colors. Cause of formation: The fossilization of wood undergoes the process of decomposing minerals to replace the original tissues, which are usually silicon or calcium. Under the action of pressure and temperature, silicon and its decomposed impurities combine to crystallize again, which usually leads to the appearance of new mineral forms. The recrystallization of silicon will destroy the structure of wood. The ancient forest was buried in the ground under the action of natural forces, and was soaked in the saturated solution of silicon dioxide under the conditions of high pressure, low temperature and lack of oxygen. The carbon element in trees is gradually replaced by silicon dioxide, which retains the original shape and structural characteristics of trees and blends with trace elements in surrounding rocks to form colorful colors. This is silicified wood. The cause is silicified wood, also known as wood fossils. Hundreds of millions of years ago, trees were buried underground for various reasons. In the stratum, chemicals around the trunk, such as silicon dioxide, iron sulfide, calcium carbonate, etc., enter the trees under the action of groundwater, replacing the original wood components, retaining the shape of the trees, and forming wood fossils through petrochemical. Because it contains many silica components, it is usually called silicified wood. This substitution is so accurate that it not only reflects the external shape, but also reflects the internal structure, and sometimes even determines the cell structure. The technical term of this replacement is "replacement", which refers to the process of simultaneous dissolution and precipitation, so that one mineral replaces another. The formation of silicified wood is a process in which silicon replaces wood fiber. Silicified wood is also a kind of fossil, which retains some characteristics of ancient trees and provides clues for us to study the history of ancient plants and paleontology, as well as geological and climate changes. Siliceous fossils are common, and there are silicified wood national parks in many countries. In the meantime, calcium and other components are filled, but it is not an metasomatism reaction. Silicified wood in Qitai, Changji, Xinjiang can be traced back to Jurassic 65.438+0.5 billion years ago. When plants (mainly conifers, cycads, ginkgo biloba, true ferns, seed ferns and other ancient tree remains over 654.38+0.5) are buried by sediments, the wood is not easy to rot because it is in a dry and water-deficient environment, but it is vulcanized by silicon dioxide or calcium carbonate in the long petrochemical process. The distribution time of silicified wood is from the Paleozoic Carboniferous (from 355 million years ago) to the Mesozoic Cretaceous (from 65 million years ago). The earliest silicified wood Up to now, the earliest wood fossils are gymnosperms of the Early Carboniferous. The latest is silicified wood in the late Cretaceous 65 million years ago.
Question 5: The radiation of silicified wood, also known as tree fossils, is mainly composed of silicon dioxide, which was formed in Jurassic and is the remains of prehistoric tall trees. Radon in silicified wood is an inert gas produced by radium decay, which can form radioactive aerosol at room temperature, thus polluting the air. In fact, radiation is still a relatively comparative thing. There is radiation in the air around us, and so does the stone ... For some time, some public media broke the news that "silicified wood has radiation and is harmful to human body". In fact, this statement is groundless. As we all know, ordinary natural jade has certain radiation and the ability to absorb radiation. Of course, silicified wood is no exception, but its radiation value is far lower than the control value in the modern Standard for Classification and Control of Radiological Protection of Natural Stone Products, and it is not dangerous to human body, because it has been close to the surface for a long time, and most radioactive elements have evaporated into the air. The story of CCTV 2' s "Story of Fortune" tells the story of "strengthening the country one inch at a time" and also mentions this statement. However, silicified wood has been tested by an authoritative testing institution in Shanghai, and it has been proved that silicified wood (tree-shaped jade) will not cause harm to human body.
Question 6: Are sunflower fossils radioactive? You can choose two answers, yes or no.
Question 7: Is there any radiation in coal mine tree fossils? I also have tree fossils from the black coal mine. Note that there are rare things in the wood fossils in the coal mine, which are made up of wood blocks. The more there are no complete annual rings, the greater the possibility. The powder of my wood fossil is brown. What about yours?
Question 8: What is this? Is it a fossil? Is there radiation? This kind of bubble is an obvious feature of volcanic rocks. The marks produced by bubbles during magma tumbling are of little value.
