Today We'll talk about the radiation outdoor.
High-voltage power lines: radiation index ★★★★★
The electromagnetic radiation intensity of a 220kV high-voltage line within a range of 100 meters exceeds 0.4 microtesla; it is safe outside the range of 100 meters.
The electromagnetic radiation intensity of a 132 kV high-voltage line within a range of tens of meters exceeds 0.4 microtesla; it is safe outside the range of tens of meters.
The electromagnetic radiation intensity of the 11~66kV high-voltage line in the range of tens of meters exceeds 0.4 microtesla; it is safe outside the range of tens of meters.
The electromagnetic radiation intensity of buried high-voltage lines only within a few meters exceeds 0.4 microtesla.
It is safe to be a few meters away.
The radiation source of high-voltage power lines is mainly 50Hz power frequency.
Communication base station: radiation index ★★★★★
The power density at a distance of 10 meters from a 2G base station is 1.13 μw/cm2, while a 3G base station is only about 0.19 μw/cm2.
The radiation source of communication base stations is mainly high-frequency electromagnetic wave radiation.
Railway Power Network: Radiation Index ★★★★★
The radiation source of the railway power network is mainly 50Hz power frequency.
