Home decoration, many people like to use marble, marble coffee table, marble tabletop, marble TV background wall and so on, do you like marble this material? But many people heard that marble radiation, long-term use will be harmful to the body, choose other materials instead. Do you want to know the truth? Today we take you through it.
A lot of people like the appearance of marble, especially like the marble used in the kitchen (kitchen decoration renderings) and bathroom, but the Internet has been spreading that the radiation of marble can cause cancer. It is reported that marble will produce radon gas, this colorless, odorless and imperceptible inert gas its daughters with the air into the human body, or attached to the trachea mucosa and lung surface, or into body fluids into the cell tissue, the formation of internal radiation, induce lung cancer, leukemia and respiratory diseases.
Online casually check the harm of marble will find that there are many kinds, such as radon gas. Radon is a colorless, odorless and imperceptible inert gas. Radon and its daughters enter the human body with the air, or attach to the mucosa of trachea and lung surface, or dissolve into body fluids into cell tissues, forming internal radiation and inducing lung cancer, leukemia and respiratory diseases. Studies by the World Health Organization show that radon is the second most common carcinogen of lung cancer after smoking. After reading these statements, you must think that marble is very harmful, in fact, it is not as scary as you think.
But in fact, as long as the house must have radon gas production, especially the old house radon production is higher than the new house. You don’t have to have marble to have radon gas. So for this so-called marble harm, we do not have to worry. The harm of artificial marble is much lower than that of natural marble on the human body.
For the online rumor of the harm of marble, people fear, we do not alarmist. Marble radiation is only natural marble, artificial marble is no radiation. Marble production standards are completely in the national Environmental Protection Agency safety range, we can rest assured to use. Marble radiation is generally below 13μGy/h. In the environmental monitoring data, you will find that the radiation below 20μGy/h (microgy/h) does not need to consider the harm. Several years of monitoring by the Environmental Protection Agency’s radiation division found that marble radiation is not harmful to human health. Because everything has radiation, but it is far from the national standard. Not only marble radiation, anything has radiation, no matter what, must meet a standard to produce harm, just like any food is bacteria, only to meet a standard, after eating will cause harm to the human body.
Buy marble is best to use natural marble, its radioactivity is very small, almost negligible, not enough to cause harm to the human body.
But there are some basic rock or ultrabasic rock stone on the market, the former is gray black or gray green, the latter is black ink or green black, easy to be mistaken for marble. These rocks are also very low in radioactivity, but there may be “small structures” in them that can easily cause fracture or damage.
The following introduces a simple way to test the authenticity of marble: test with dilute hydrochloric acid, if it is calcite, will be intense foaming; Dolomite, although bubbling, but weak; This phenomenon does not occur in mafic or ultrabasic rocks.
Experts suggest that whether to buy natural marble or artificial stone, be sure to ask businesses for radioactive and harmful gas index proof, or please professional inspection institutions for detection. The Nuclear Science and Technology Development Centre provides this kind of testing service to the public.
