Every day in life there is radiation. Mobile phone radiation, microwave radiation, computer radiation, the hospital filming film should eat a lot of radiation.
First simple science about: the so-called radiation, in fact, is a phenomenon of energy transfer. For example: the sun also has radiation. We sun every day, is to accept the sun to our energy.
Radiation is divided into two types: non-ionizing radiation and ionizing radiation. Non-ionizing radiation on the human body is minimal, almost negligible; and hurt the ionizing radiation! Is ionizing radiation! Is ionizing radiation! Important thing to say three times!
So what is the radiation around us?
First, home
- mobile phone
Type: Non-ionizing radiation
Radiation: standby state is basically 0; call the moment to reach 3μt, far greater than the safety value of 0.2μt.
Recommendation: Use a headset for long calls. Sleep, the phone do not put on the bed, to 1.5 meters above the distance is appropriate.
- microwave oven
Type: Non-ionizing radiation
The amount of radiation: the equivalent of listening to the radio. In the microwave oven, the amount of radiation from 0 to 65 cm in the main gate drastically decreases, and the amount of radiation at the distance of 70 cm from the main gate is zero.
- electric blanket
Type: Non-ionizing radiation
Radiation: When the electric blanket is open, the radiation value is 16.69μt. Indeed, the safety value is much larger than 0.2μt.
Recommended: use, as far as possible in advance to open the preheat, sleep and then closed.
Second, the office
WIFI router
Type: Non-ionizing radiation
Radiation: WiFi signal on the human head caused by the radiation value of only 0.0057W / kg, well below the specified safety value of 1.6W / kg.computer
Type: Non-ionizing radiation
Radiation: computer LCD monitor display 0.5 meters before 0.11μt, the host on / standby status is 0.17μt.Copier
Type: Non-ionizing radiation
Radiation: only 1/9 of the computer. Recommendation: When used, keep the machine running for more than 30cm distance and keep it ventilated.
Third, the hospital check
CT
Type: ionizing radiation
Radiation: sweeps the amount of radiation for 20 millisieverts.X-ray film
Type: ionizing radiation
Radiation: The amount of radiation is 0.2 millisieverts.
- chest through
Type: ionizing radiation
Radiation: The amount of radiation taken is 1 to 2 millisieverts.
Above for non-electric radiation, in addition to hospital inspection is ionizing radiation. But experts say that less than 100 milliseconds talk about health effects is making panic. So, we should eat, the drink, the inspection or to check, as long as the abuse of Kazakhstan on the line ~
