When it comes to the word "radiation", many people are afraid of the first reaction.
WiFi has radiation, computer radiation, microwave oven radiation, security door radiation, cell phone radiation, base station radiation... Originally there is radiation everywhere on the earth?
Is there any radiation in the communication base station?
Although the base station has "electromagnetic radiation", the base station follows the national "electromagnetic environment control limit" construction, and the environmental impact assessment will be carried out after construction. China has strict requirements for the management of electromagnetic radiation of base stations. The current national standard "Electromagnetic Environmental Control Limits" is far below the international standard limits.
Taking the GSM base station at 900MHz as an example, China's standard limit is 40 microwatts per square centimeter, which is 10 times lower than the standard of European developed countries (450 microwatts per square centimeter)!
Public exposure control limits and exemptions for electromagnetic radiation
Public exposure control limits for electromagnetic radiation
In order to control the electric field, magnetic field, electromagnetic field to the public exposure, the square root of the electric field, magnetic field, electromagnetic field field parameters in the environment should meet the requirements of Table 1.
Exemption range for electromagnetic radiation
From the perspective of electromagnetic environmental protection management, the following facilities (equipment) that generate electric, magnetic, and electromagnetic fields are exempt from management.
——AC power transmission and transformation facilities with voltage levels below 100KV.
——A facility (equipment) whose equivalent radiated power is less than the value listed in Table 2 when transmitting an electromagnetic field of 0.1 MHz to 300 GHz without shielding space.
The more base stations, the smaller the radiation will be.
The radiation intensity of the mobile phone is closely related to the signal strength of the base station. The farther the mobile phone is from the base station, the weaker the signal and the greater the required transmission power.
This is like talking to two people. The farther away, the louder you should cry out; the closer you are, the more you can whisper.
If you think about it further, you can understand that the density of the base station is large, the signal is good, and the mobile phone is easy to receive. Therefore, no matter whether it is a base station or a mobile phone, it does not work so hard, and the radiation is correspondingly reduced.
In short, the communication base station has nothing to worry about, if it is built near the community, it is actually hello, hello, everyone.
Electromagnetic radiation management agencies and management monitoring methods
Electromagnetic radiation management agency: Radio Management Committee, Human Settlements Committee
Management monitoring means: use electromagnetic radiation detector, electromagnetic radiation tester, electromagnetic radiation analyzer, electromagnetic radiation measuring instrument, electromagnetic radiation measuring instrument and other testing equipment to measure and evaluate electromagnetic radiation, and do not comply with the standard order rectification.
Manual Glass cutting table is one economic glass cutting model that include two models,one model named semi-automtic Glass Cutting Machine,need manual loading and cut only rectangle or square glass;the other model named three arm-functional cutting table,which is the one can automatic loading glass but manual cut glass.
Semi-automatic glass cutting machine adopt PLC control system for easy setting of cutting speed and size,and wih air floation breaking function.
Three arm-functional cutting machine choose the wireless remote control system, it works more flexible and adapts to a variety of working environment.
