Q:Does the 400V cabinet have radiation?

Any electrical appliances have, but the size is different. In general, are within safety limits

Q:Four-dimensional color Doppler in the end there is no radiation?

4, four-dimensional color Doppler ultrasound can automatically shoot on the fetus "photo" and dynamic video, for many mothers to add peace of mind and fun. Mothers can not only feel the baby's breathing and movement, and can witness their every move and show capacity. Healthy baby, and the baby's appearance and action into a photo or VCD, let the baby has the most complete 0-year-old album.

Q:My house is a three-storey private residence, the telecommunications optical splitter installed in my house roof, do not know if it has no radiation, my family has no effect?

There is radiation, but the radiation is very small. The Completely negligible, the equipment is wrapped in iron. The metal can block the radiation. So there is no need to worry.

Q:Partial discharge characteristics

1, the local discharge is a local overheating, electrical components and mechanical components of the signs of aging; 2, the partial discharge trend is the rise of the PD over time, which is a tortuous process, a stage may decline, but a certain stage of the rise.

Q:My house has a radio and television room downstairs, I would like to ask the equipment how much impact on the human body radiation?

Certainly more or less radiation, the body will become increasingly weak

Q:Is there a cable TV box in the corridor and the fiber sub - box

There is no radiation, Take a radio, put around, Listen to the radio there is no abnormal sound.

Q:Is the electromagnetic radiation of the solar light plate big?

Internal energy into chemical energy, if you want to use electricity, chemical energy can be converted into electricity, you say that radiation is not big

Q:Does the computer not turn on the power supply only?

Desktop, then the general compatible machine is relatively large, brand machine is relatively small. Concrete is not good to say, there are always special circumstances, but not sure to start a lot better than boot Under normal circumstances, there is no relationship between the boot, did not boot, then there is no operation, no heat, no radiation source.

Q:I would like to have a child, to be over the years to work, My mother told me to go to the weaving factory to work, there are On a few hundred machines, there are thousands of fluorescent lamps, factories Very big, know what kind of weaving machine What am I worried about! I heard that pregnancy can not be radiated Shoot, so many machines, they have radiation?

We often say that harmful radiation, refers to the radioactive objects in a series of physical changes when the launch of a 'wave', it generally has high frequency characteristics, such as microwave inside the microwave, the phone signal radiation - Very small on the human body is basically harmless, fluorescent light Han, due to the large wavelengths of light emitted, the frequency is low, so harmless

Q:Light, heat, sound, electromagnetic waves, these radiation, which radiation damage

Of course, electromagnetic waves, and electromagnetic waves is a kind of light, but the radiation is greatest, the sound and heat radiation is small, but other forms of energy Shanghai big!
