Abstract Objective To make the public to understand the distribution feature of electromagnetic radiation in nearby regions around the mobile communication base stations,and provide reference for the environmental monitoring department to choose the Monitoring periods and points.Methods Through 24-hour surveys and analysis of electromagnetic radiation in the nearby region around the representative mobile communication base station,the radiant intensity change vs the time and distance in normal operating day.And based on the telephone traffic and Antenna characteristic,the Space-time distribution characteristics of radiant intensity were also studied.Results The result showed that the electromagnetic radiation intensity near the antenna of mobile communication base station had obviously fluctuated character in one day,and the distribution of its power density approached "Μ" type distribution,and it possessed positive relativity with the telephone traffic.Around base stations,the power density showed clear changes with distance,The power density approached "Λ" type distribution in the nearby region.the peak value of power density was related with Antenna characteristic.Conclusions The environmental monitoring department ought to choose the suitable monitoring periods and points according to the telephone traffic and Antenna characteristic,so as to find out the main influence of the basement on the environment of electromagnetic radiation.
