What are the rumors about radiation?
Electric razor, hair dryer
Use the shorter the better, as far as possible away from children, open and close the power also away from the body.
Computer, TV use to keep the distance, watching TV, the best to keep 2 meters away, the room should have the appropriate lighting, watch time not more than two hours.
Rumors of five doorsteps with base station radiation?
In accordance with the relevant provisions of the state, telecommunications facilities should implement the national electromagnetic environment control standards, according to the law for environmental impact assessment procedures.
The construction unit shall detect the electromagnetic radiation status of the mobile communication base station and announce the test result to the society. Citizens, legal persons and other organizations have objections to the test results and may file a complaint with the competent department of environmental protection.
The competent department of environmental protection shall supervise and manage the pollution of electromagnetic radiation according to law, and report the investigation and handling of complaints in a timely manner.
To give an exaggerated example, even if people put into the subway, the train station used X-ray security device, to scan about 100 times to reach a chest radiation received by the dose.
However, pregnant women and children still try to avoid the above situation, although the small dose of security, may also cause some radiation on the body.
Rumors of four home appliances radiation induced gene mutation?
Some people worry that home appliances radiation will have an impact on human health, and even claims that home appliances radiation not only induced gene mutation, to promote the production of mutant cells, but also disrupt the secretion of hormones, affecting the central nervous system, leading to neurasthenia.
But in general, each home appliance has a fixed operating frequency of the national standard (marked in the product specification). In the same work intensity, the higher the frequency, the greater the radiation effect on the human body.
Microwave oven
At the start of the door at the maximum electromagnetic radiation, but the microwave can absorb the electromagnetic waves, cut off the electromagnetic waves, even if the cooking is not too close.
B super
It is two dimensions of ultrasound information, without any radiation.
X-ray
Penetrating very strong rays, only the body to accept the dose and time beyond a certain value, will cause damage to the body.
The risk factors of medical equipment are strictly defined and stated, belong to the scope of human safety, do not worry too much too much radiation.
CT examination
Similarly, X-ray, a CT scan to the patient to bring the dose of about a few cents Schwartz (radiation dose unit), the dose per person per year to accept the natural amount of radioactive radiation equivalent.
Patients can be based on the disease in the scientific control of the dose (no more than twice a year) under the premise of the discretionary examination.
Magnetic resonance examination
Do not use X-rays, so there is no radiation.
Rumors three security machine inside the radiation strong?
In the train station, airport, subway station, a lot of passengers have not had a package of security machines, anxious to reach into the handle, some people think that this is very dangerous, because its internal radiation is very strong.
Baggage X-ray detector and medical X-ray diagnostic apparatus, are by X-ray exposure to be detected object to obtain the internal image of the object, but the radiation dose is much smaller than the medical X-ray diagnosis.
There are a lot of rumors about radiation in life, so these rumors are actually false.
Rumors one: mobile Internet will be more than usual 50,000 to 60,000 times the electromagnetic wave
According to the WHO survey, long-term exposure to electromagnetic waves, about 3% to 5% of people will suffer from electromagnetic wave susceptibility. There are experts to remind that electromagnetic waves and plasticizers are 2B (carcinogen grade) may be carcinogenic, should be far away. However, mobile phones, printers, WiFi routers and other electromagnetic radiation in the majority of the national security limits within the standard.
Mobile connection, the phone emits electromagnetic waves and calls almost the same, much lower than the human body safety radiation warning value, its penetration is much lower than the visible light. For example, wearing neatly walking in the sunshine under the electromagnetic radiation energy intensity, is the body naked tightly clinging to a cell phone sleep 60 times, so the phone generated radiation is negligible.
Rumors two X-ray inspection is equivalent to flying 20,000 km flight?
Many people go to the hospital to do B ultrasound, X-ray, CT, magnetic resonance imaging (MRI) and other checks, worry about radiation damage to the body, it was called "do an X-ray radiation dose, Km ". This understanding is one-sided.
