In a high-tech era, more and more products are boasting about the benefits of "negative ions".
Everything from hair dryer to purifier, from kettle to mattress can be negative ions. If urbanites have any anxiety, negative ions can solve any problem.
Recently, however, some netizens bought a pack of negative ion powder claiming to be able to in addition to formaldehyde from the Internet, and found that the radiation exceeded the standard.
?
According to the national standard, the annual average effective radiation dose to the public should not exceed 1mSv, that is, it should not exceed 0. 1 microsievert per hour, but this powder reaches 56 microsieverts per hour, which is 560 times higher than the standard. Next to this powder, every 2 hours, the radiation amount is equivalent to a chest X-ray.
If this powder is inhaled into the lungs, it may also form radiation in the body, which is equivalent to installing a miniature nuclear reactor in the body, and the risk of cancer increases sharply.
What's more, there are many negative ion products under the banner of "high technology", which are full of this dangerous radiation powder.
If other health care products are just cheating money, then some negative ion IQ taxes are fatal.
Many products have entered the "high-tech ranks" because of the addition of negative ion powder, and their prices have doubled several times.
But in fact, from 20 15, it was reported that negative ion products exceeded the standard.
20 17 Xinhua news agency also issued a special manuscript to remind consumers that Fuzhou airport has handled many incidents of radiation exceeding the standard, and most of the radiation sources came from sanitary articles brought back from abroad.
The report said:
Although the shapes, ornaments, bracelets or bath products of these "health products" with excessive radioactive substances are different, they all have some common characteristics:
First, it was purchased from Japan;
Second, merchants claim to contain precious or rare metals such as titanium and germanium, which can release negative ions or emit far infrared rays, and have the effects of accelerating blood circulation and supplementing human energy;
Third, they all contain radioactive nuclide thorium -232.
?
But it doesn't seem to attract widespread attention. I wonder how many products added with "negative ion powder" have been put into the market in recent years. ...
In fact, the radiation pot should not carry negative ions.
Negative ions, as the name implies, are negatively charged oxygen ions in the air.
In daily life, there are many pure natural negative ions.
For example, under a waterfall, water molecules fall from a height and rub with the surrounding air to produce charge separation, which will produce negative ions; Another example is the photoelectric effect formed by the tip discharge of trees and leaves in the forest and the photosynthesis of plants, which will also ionize the air and produce negative ions.
The same power principle is applied to life, and there is also a "negative ion generator" device.
?
The negative ion generator will generate a strong electrostatic charge. After they collide with dust particles in the air, they will of course adsorb and settle, achieving a certain purification effect.
Put this small device into an electrical appliance, which is a common negative ion air purifier on the market. Then the merchants add marketing packaging, negative ions = air vitamins = forest flavor = the secret of the hometown of longevity, and a scientific and technological machine should be born.
It should be noted that although corona discharge is a relatively safe way to obtain negative ions, it will also release ozone.
If the ozone concentration in the air is too high, it may damage the respiratory tract and lungs. Although the ozone produced by most qualified products in the market will not obviously exceed the national standard, it is still not recommended to use negative ion functional appliances in closed rooms for a long time.
?
In addition, tourmaline (also known as tourmaline, tourmaline) can release negative ions through the change of humidity and air pressure because of its special piezoelectric effect.
However, tourmaline is not very active. Experiments show that the negative ions released by tourmaline can only be detected within a distance of 20cm, and the effect of removing formaldehyde by this method is actually very limited.
Basically, a conclusion can be drawn here.
Negative ion electrical appliances can indeed adsorb harmful particles, but the scope of action is limited, and harmful particles do not disappear out of thin air, but fall freely indoors; Negative ion hair dryers also rely on static electricity to make hair attract each other and look more supple.
How can I say this effect? To sum up:
"Said useless, maybe a little useful; But if you want to say it is unique, if you have the spare money, I won't stop it. "
?
So, why do those deadly negative ion products have radiation problems?
Natural radioactive substances can also make molecules in the air free, thus producing negative ions. And the stronger the radiation, the higher the readings they show on the negative ion concentration meter.
Therefore, for the product effect, the "negative ion powder" sold by merchants is often not pure tourmaline powder, but may also be mixed with radioactive powder such as monazite and radium.
Gamma rays produced by radioactive substances have strong penetrating power and high energy, which are easy to cause DNA breakage in biological cells, and then cause cell mutation, loss of hematopoietic function, and induce diseases such as cancer.
?
There is a worse possibility, that is, even the powder seller himself is too stupid to tell which is which.
?
Monazite contains thorium series and uranium series natural radioactive materials, which will produce and release radon gas when it decays.
Radium stone contains radium, and its half-life is 1600 years. Now it is used in cancer radiotherapy in medical field.
It is worth noting that negative ion powder is not only sold separately, but also often added to other health care products as accessories.
?
There are various products with excessive negative ion radiation seized by local customs, including but not limited to health pads, health belts, mattresses, etc. ...
?
Dalian Customs even intercepted a radium stone brought back from Japan by passengers, with a radiation value of 850 μSv per hour, exceeding the standard by more than 6,000 times.
The passenger admitted that he had planned to cut the stone into small pieces and polish it into a "radium stone health bracelet".
?
We have reason to suspect that all kinds of health care products using "negative ion" powder may contain the risk of radioactive substances exceeding the standard.
Human beings have paid countless painful prices for their ignorance and ignorance, especially in radioactive materials.
Today's China businessmen cut leeks and package radium stone into "negative ion" health products. In the process of publicity, they never mentioned radioactivity, only negative ions and imaginary health effects.
They may not know how bad America was 100 years ago.
Madame Curie published a paper after extracting radium, pointing out that radium kills cancer cells much faster than normal cells, and it has an immeasurable prospect in the medical field.
People who know little about radium are refreshing, and scientific progress has brought hope and light to people.
Soon, businessmen beat us to it and packaged radium into an anti-cancer miracle and a good health care product, and added it to toothpaste, bread, cigarettes, medicines and cosmetics. ...
?
There has been a radium frenzy in the market, which is even worse than today's "negative ion XX".
The miraculous effect of radium is getting bigger and bigger like a snowball, and it soon becomes a magic medicine to keep young and cure all diseases.
In addition, the watch dial is coated with a radium-containing coating, which is convenient for troops to March at night because it can make fluorescent articles glow.
?
Although radioactive elements can cause harm to the body, radium has been used as a dial lighting material for more than 40 years. However, it has been replaced by harmless tritium or radiation-free strontium aluminate in modern times, so it can be worn with confidence.
Let American radium enterprises make a fortune in World War I.
Groups of "lucky" girls were specially hired to the factory to plate the dial with radium.
In order to save costs, when the brush tips in their hands split, the radium boss encouraged the female workers to take a sip with their mouths.
?
Didn't the advertisement say to prolong life? How many companies can provide such high benefits?
Girls also apply radium to their teeth and nails, go to bars at night to entertain themselves and shine in the crowd.
Soon, many of them suffered from similar diseases: anemia, and pain in their teeth, chin and joints all over their bodies.
The most obvious features are jaw enlargement and gangrene on bones.
?
When the dentist pulled out one of the girl's teeth, part of her chin was torn at once.
Eliminate decay.
At this point, her mandible has rotted like a honeycomb, and there are small holes everywhere.
Later research called this disease radium jaw, and the human body mistook radium for calcium and absorbed it into the body.
But calcium makes bones stronger, while radium destroys bone tissue, making it swell and then rot.
?
The first group of female workers fought hard for two years, and finally the two sides settled out of court and got high medical compensation, but most of them died within 10 years.
Under the cover of American radium enterprises, the problem was completely exposed until another more influential figure was killed by radium.
If the daily necessities containing radium in front of you may be just a gimmick, then Radithor made of radium and distilled water by an American company is really fatal.
?
Radithor's advertising slogan is "Cure the Living Dead" and "Eternal Sunshine", and the instructions are even more fierce: this product can cure indigestion, hypertension, impotence and other 150 kinds of diseases caused by endocrine system.
Treat the disease, strengthen the body without disease.
Many celebrities are also willing to pay for this, and the golf champion and steel giant Eben Beyers is one of them.
He drank 1400 bottles of this "rejuvenation" potion in three years until …
Like Miss Radium, except for two upper incisors, his entire chin and mouth were removed.
?
He was finally buried in a lead coffin. At the time of autopsy, his bones were rich in radium, and even the outline could be shown on the photo negative. At this time, Radithor has sold a total of 400,000 bottles.
His tragic death really aroused public vigilance against radioactive materials.
Articles containing radium were finally banned by the FDA in the late 1930s, but luminous watches did not completely withdraw from the market until the 1960s.
Unexpectedly, after such a painful tragedy in other countries, this trend has the meaning of making a comeback in 2 1 century.
Ordinary people are always in awe of what they don't understand at all.
When watching sci-fi movies, everyone was shocked by throwing out a few big characters:
In the case of indecision, quantum mechanics;
Style jumping, virtual world;
Unreasonable, through time and space;
……
It is no problem to justify yourself in fictional works, and it is no problem to use it in advertisements for daily necessities and health care products.
After all, our people's understanding of science is still very simple.
?
Before the Han Dynasty, people wrote magnets as "Ci Shi", which means to love stones. Just as a mother attracts a child, a magnet is the attraction of love.
In the second year of 2 1 century, we still made little progress.
Today's businesses only need to abstract radiation into "energy", and they can capture the vast number of health lovers and blessing lovers.
No matter what radiation does not radiate, people only recognize "energy", from fatigue, physical weakness and sub-health to dizziness, hair loss and impotence. In the final analysis, it is all "insufficient energy".
From space, the seabed, volcanoes, minerals, exotic customs, flying fairies, can be packaged into potential health artifacts.
Whether it is soaking in wine, making tea, playing with it, or carrying it with you, it is good for your health and can give you "energy".
In the United States from 65438 to 0950, some people put radioactive minerals in their pockets and sold them, calling them "cosmic bags", claiming to have miraculous effects on arthritis.
?
But in terms of jumping and creativity, East Asians are definitely better.
We can intuitively draw the conclusion that this kind of thing kills two birds with one stone-both healthy and transshipment.
On the 9th of last month, at Zhoushuizi Airport in Dalian, a passenger who entered Dalian from Japan triggered the customs nuclear radiation alarm when entering the country.
After some investigation, the customs found that it was the "five-element proton quantum energy vibrator" carried by the passenger that was detected to have exceeded the standard.
?
This artifact, which combines the theory of oriental five elements and western quantum physics, is equivalent to doing 100 chest x-rays every day.
According to the passenger's account, this "energy stone" was bought by her mother at 400 yuan. The material is taken from the deep sea, which can promote blood circulation and is also a "feng shui stone" to maintain peace.
It was not until she heard the explanation from the customs staff that she realized that it was no wonder that she often had nosebleeds after wearing this energy stone for three months. ...
The paradox of medical care for middle-aged and elderly people in China is really elusive. Obviously, the first thing for a daughter-in-law to get pregnant is to buy a radiation protection suit and give her grandson blue glasses. Can the plane sit? I'm afraid of radiation.
But if you want to go to the radioactive radon hot spring for health care, you will jump in without blinking.
?
The World Health Organization has long said that it causes cancer.
?
Or Zhao Benshan, a famous doctor in the art world, put it well:
?
Advertisements can blow cigarettes into "doctor's choice", opium can be called "Fu Gao Shou", and negative ion powder is always young. How can you trust them?
Unscrupulous businessmen who brag are just cheating some money, and "conscience" businessmen who come up with real things are often suicidal.
Of course, in addition to the vigilance of consumers, quality inspection departments, e-commerce and offline sales platforms should introduce more detailed regulatory measures for negative ion products as soon as possible.
Although China is a big country with rare earths, it is really full of doubts that ordinary people can buy radioactive ore powder casually on the Internet.
In the middle, it is obviously a blank area of supervision.
At present, some e-commerce platforms have actively hidden the search results of "negative ion powder".
After the negative ion powder radiation detection video was exposed, some netizens anxiously asked:
What should I do? I won't buy it myself, but what if I meet a neighbor who can't relax and uses "negative ion powder" as a dead hole in addition to formaldehyde?
Then you'd better send this article to him at once.
