What is radiation pollution from hairdryers?

The hairdryer consists of a set of electric heating wires and a small fan. When energized, the heating wire heats up, and the 

wind blown by the fan passes through the heating wire to become hot air. This is a kind of electromagnetic radiation.

Test data show that the radiation value of a general household 1000W hairdryer is about 350mG (mG: milligram is the unit 

of magnetic field strength), while the radiation value of televisions and computer monitors is about 45mG and 100mG, which 

is much lower than that of a hairdryer.

This is because when using a hairdryer, the magnetic field may be larger due to the high power and current.

However, it is not the same as the radiation produced by X-rays used in medicine. Radiation from hair dryers is electromagnetic 

radiation, while X-rays used in medicine are ionizing radiation. These two types of radiation are different and cannot be compared.

In addition, the radiation from a hair dryer is different from the radiation from cell phones, computers, microwave ovens, and so on. 

Electromagnetic fields from cell phones, microwave ovens, computer cases, etc. are radio frequency electromagnetic fields. The 

energy of electromagnetic fields is relatively large and poses a great threat to the human body.

Hairdryer belongs to the low-frequency electromagnetic field, there is no heating effect of radio frequency electromagnetic field.

The main possible threats to human health are: low-frequency electric fields and low-frequency magnetic fields can generate or 

induce electric currents in the human body. If the current is large enough, it will stimulate the nerves and muscles. However, to 

produce this stimulation, the electromagnetic field itself must be energetic enough. A home hair dryer will never reach this "level",

 so you can use it with confidence.

Avoiding hairdryer radiation protection

1. When using a hairdryer, it is best to keep it perpendicular to your head and at a distance.

2. Try to stay away from the hair dryer when switching it on and off.

3. Do not use the hair dryer for too long. If continuous use is required, it is best to use it intermittently.

4. Installing magnetic materials such as iron sheets on the inside of the handle of the hair dryer can effectively reduce the electro-

magnetic waves generated by the hair dryer.

In summary, although the hair dryer will produce a certain amount of electromagnetic radiation, but only when the current reaches 

a certain level will cause harm to the human body, so we do not have to worry too much about its electromagnetic radiation pollu-

tion will threaten our human health.
