Jing Bao: range hood 1 minute irradiation = phone 300 times?
Recently, the Internet is reproduced a news: the Swiss National Laboratory appliances electromagnetic radiation test report, the kitchen range hood is the radiation released by mobile phone 300 times, that is, if the hood before cooking 1 minute, equivalent to a cell phone 300 minutes.
The hood of radiation in various reports, the reporter found that introducing a smokeless wok finance and economics media articles, is the source of radiation range hood. The article said that if the use of smokeless wok, will not need hood, much less exposed to radiation hazards. Online news also said the cooker hood of the circuit can attract radon radiation belt particles, and radon gas can lead to more than 40 kinds of cancer. Where there will be the release of electromagnetic energy of substances, electromagnetic waves has a cumulative effect, once invaded the body, will continue to lurk in the body tissue, the waiting time induced by the arrival of cancer, they put a long-accumulated toxins burst out!
State Quality Supervision and Inspection Center, a home appliance department heads, Mr. Song told reporters: appliances electromagnetic radiation is not in the scope of mandatory state testing, but also very few companies that offer to test them, their electromagnetic radiation impact on human health has not done much research, this inconvenience comment. But when asked whether the international attention on the electromagnetic testing, he told reporters with certainty, electromagnetic radiation on human health is currently a hot topic internationally in recent years, many foreign official institutions are conducting research in this area.
Beijing Institute of Labor Protection
head of Mr. Huang Jiusheng told reporters: General Electric use electrical power generation, its frequency band generally maintained at about 50 Hz up to not more than 5000 Hz, this part of the electromagnetic appliances can be difficult radiation out. But we do not rule out the possibility that large consumption of electrical appliances, they may be using radio frequency techniques, the moment may be hundreds of megabytes of electromagnetic fields, which may generate electromagnetic radiation. In life of such CE is the most common air-conditioning, but now Henduo Air Du adopted frequency conversion technology, so time may not Ta tremendous radiation to the man who is not close to Jia Dian Zhang Shijian, electromagnetic radiation is not likely to exercise direct impact. But the range hood is a hundred times the radiation in the phone, he did not rule out the possibility that a special type of range hood, range hoods, but the frequency of ordinary household not produce radiation, for the news should not be so dire.
China CDC Environmental Health and Related Product Safety Cao Institute researcher, they have carried out electromagnetic radiation on central nervous system, nervous system, immune function, reproductive system, eyes, and in tumors. They have carried out cell phones and human health research project, the conclusion is: cell phone radiation on human health effects is not too much. Because the range hood radiation theory mentioned radon gas, this reporter interviewed to study the issue of China's leading experts, the Chinese Center for Disease Control Institute for Radiation Protection and Nuclear Safety, researchers are still soldiers, still soldiers fellow that: we do not need to radon that panic, as the inert gas radon, in a normal environment in the air in small concentrations, and other material will not readily react chemically, even if the range hood of radon through the electromagnetic field to attract a large number of particles do not have to panic, because the smoke itself can absorb radon gas and the resulting emissions, constitute the fundamental risk of radon radiation. For the 40 kinds of radon can cause cancer of speech, she said, and now the international scientific conclusions would only prove that radon causes lung cancer, but these cases are from a special natural environment, not in everyday life more common, other types of cancer, saying it is unfounded.
Although the range hood with radiation experts say basically negative, but we can not overlook the kitchen oil fumes. Kitchen gas combustion process, the formation of nitrogen oxides will surge, resulting in a large number of hazardous substances, human inhalation causes lung disease later appeared asthma, bronchitis, emphysema and other diseases, severe cases can lead to pulmonary fibrosis consequences. Experts suggest that we want to change cooking habits, not to overheat the oil temperature, oil temperature not exceeding 200 oil with smoke as the limit at the same time we must do the kitchen ventilation in the cooking process should always open the hood.
