Every year, at least 4 million children in Italy develop leukemia, a blood disorder caused by the abnormal proliferation of malignant cells in the bone marrow. At present, the research on childhood leukemia in the world is unclear and may be related to genetic factors, environmental factors, and immune system abnormalities. Some studies have suggested that certain genetic mutations may be associated with the development of childhood leukemia.
Italian experts have found that about 400 children suffer from leukemia every year, and they all have one thing in common: they live in houses with underfloor heating. The surge in children with leukemia may have something to do with the widespread use of underfloor heating in the country.
Based on this, experts believe that:
The leukemia in these children is caused by geothermal radiation, which causes genetic mutations in normal human cells, giving rise to cancer genes and causing cells to become cancerous.
Not only that, underfloor heating radiation also affects the human reproductive system, so that male reproductive ability is reduced, at the same time, it can also affect the human nervous system, damage the intelligence.
Underfloor heating, also known as radiant floor heating or underfloor heating, is a heating method that transfers heat to the indoor space by installing heating equipment under the ground, and underfloor heating mainly uses the principle of radiative heat transfer from the ground to provide a comfortable indoor temperature.
There are mainly these components of the floor heating system.
One is the heating equipment, and the most common heating equipment in the floor heating system is the floor heating pipe or electric heating film. Underfloor heating pipes are pipes laid under the floor, and then the heat is transferred through circulating hot water or other heat medium. Electric heating film is an electric heating system, which is mainly installed under the floor to heat the floor.
Then there is the temperature control system, which is usually equipped with a temperature control system that is used to control the temperature and working hours of the heating equipment. The climate control system adjusts the room temperature as needed to provide comfortable heating.
Finally, there is the heat dissipator, which in the floor heating system refers to the medium between the floor heating system and the indoor environment, usually the floor material. Floor heating warms the ground by transferring heat to the indoor space through the heat dissipation body, and transfers heat to the indoor air through radiation and convection, so as to achieve the effect of heating.
In the north of the mainland, almost every household needs to use floor heating, otherwise it will be difficult to survive the winter, and the research of Italian scientists has frightened the people who are using floor heating.
Today, let's take a look at whether floor heating will kill delicate cancer through scientific experiments.
Underfloor heating, is there radiation in the end?
Asking such a question proves that everyone is not very familiar with floor heating.
The classification of floor heating is mainly divided in this way,
According to the classification of heating methods, it can be divided into electric floor heating, which uses electric energy for heating, and generally uses cables or heating films for heating. and water underfloor heating, which uses equipment such as boilers or solar water heaters to heat water through hot water circulation pipelines, and then transports hot water to the ground through pipelines for heating.
If classified according to the installation method, it can be divided into seamless floor heating, that is, the cable or heating film is laid under the ground, and then covered with insulation materials and floors. Knitted underfloor heating, the underfloor heating pipes are woven into a mesh fabric, laid directly under the ground, and then covered with insulation materials and floors.
In addition, it can also be divided into ceramic floor heating, carbon crystal floor heating, film floor heating, copper tube floor heating and so on according to different materials.
Among so many floor heating, there is actually only one type of electric floor heating that can release ionizing radiation.
Electric underfloor heating is actually a way to use electrical energy to heat the ground, so as to achieve indoor heating. It is generally installed under the ground, with electric heating equipment such as electric heating film or electric heating cable, which transfers heat to the ground, and then transfers heat to the indoor space through radiation and convection.
The advantages of the electric floor heating system are that it is easy to install, fast to respond, and can be used for local heating as needed, and is not limited by the layout of pipelines.
So whether it will produce radiation, and how much radiation it will produce, we must find out.
To this end, a CCTV reporter and Dr. Wang Ansheng, a floor heating expert, wanted to make a simple measurement of the radiation of floor heating.
The results show that the amount of electromagnetic radiation from floor heating is actually very low.
During the test, Dr. Wang Ansheng took an electromagnetic radiation collector to monitor the amount of electromagnetic radiation in the environment, and found that the amount of electromagnetic radiation in the environment was only 0.3 microtesla.
Even when the temperature rises to 32°C, the total amount of electromagnetic radiation in the house is only 0.08 Tesla, and at this time, the room is actually very stuffy.
In addition, Dr. Wang Ansheng also measured the total amount of electromagnetic radiation from household appliances such as induction cookers and mobile phones in the house, which is 20 and 0.39 Tesla, respectively, which is much higher than the radiation of floor heating.
In addition, Dr. Wang Ansheng popularized science: "The radiation wave frequency of floor heating is only 50 Hz, far lower than the 900 MHz of mobile phones and 333 MHz of computers", so the radiation generated by floor heating to the human body is negligible.
Mobile phones, computers, and some household appliances are really dangerous and should be kept away.
So why is there so little radiation from electric underfloor heating?
It is very easy to understand, because the radiation source of electric floor heating is mainly the heating element - the heating cable, and the heating cable is a conductor, where does it have the ability to radiate radioactivity?
Because of this, the radiation level of electric underfloor heating is very low compared to other household appliances.
In addition, electric floor heating will directly transfer heat to the ground and the surrounding environment when working, instead of heating or cooling the room through air like air conditioning and other equipment, thus avoiding airborne heat radiation and reducing the impact and harm to the human body.
Therefore, the rumors that floor heating causes cancer and spermicide, but this has led to a new question, floor heating is no problem, what are the curing factors that cause cancer and endanger human health?
Underfloor heating is not to blame, but it may be an accomplice
Floor heating mainly provides a heating and thermal insulation effect for the room, but when the indoor temperature rises, it will actually produce a series of problems.
The most serious problem is the release of formaldehyde.
Formaldehyde is a colorless volatile organic compound with a pungent odor, it is the simplest aldehyde compound, also known as formalin. Formaldehyde is widely used in industry to make resins, coatings, adhesives, etc., and is often used as a preservative.
In everyday life, formaldehyde may also be present in products or environments such as furniture, upholstery materials, flooring, glue, tobacco smoke, etc. Due to its volatile nature, long-term exposure to formaldehyde-containing environments can cause health effects. Formaldehyde is considered a potential carcinogen and may also cause irritation of the eyes, nose and throat, leading to discomfort.
The heating and thermal insulation function of floor heating has a promoting effect on formaldehyde.
First, it will increase the release rate.
Formaldehyde is a common indoor volatile organic compound, often derived from new furniture, decoration materials, carpets, glue, etc. At higher temperatures, the rate of formaldehyde release in these materials increases, leading to an increase in indoor formaldehyde levels.
Second, the speed of chemical reactions is promoted.
Rising temperatures can facilitate the reaction of formaldehyde with other chemicals in the air, such as oxygen and nitrogen oxides. These reactions may produce more formaldehyde decomposition products, increasing indoor formaldehyde concentrations.
Third, poor ventilation.
In hot environments, it is common for people to close windows and doors to maintain the temperature indoors, resulting in poor indoor ventilation. Without the circulation of fresh air, indoor formaldehyde concentrations may rise.
Because of this, people may absorb a large amount of formaldehyde indoors, which has the ability to cause cancer and teratogenesis, which makes Italian children continue to suffer from leukemia.
How to avoid such problems?
Once you know what the problem is, it's easy to deal with it.
First of all, you must choose high quality when decorating your home.
Furniture market, decoration team, etc. will often cut corners, shoddy, with those things with high formaldehyde content to deal with things, if your home is high formaldehyde furniture, then the use of floor heating when formaldehyde does not volatilize are a little difficult.
Secondly, it should be ventilated more.
Many families in the north close their doors and windows in winter, afraid of the cold wind entering, which is actually wrong, indoor closure will not only make the formaldehyde concentration higher and higher, but also make the content of carbon dioxide and other gases higher and higher, which has a serious impact on human health, the correct approach should be to open the windows regularly for ventilation, and turn off the floor heating regularly, so as to reduce the production of harmful gases.
In short, the safety of floor heating has been recognized by the state, and there is no evidence and experiments, don't talk nonsense, but you should also pay attention to what the doctor says when using floor heating, and hope that everyone will spend the winter in health and safety.
