(1) For more than 10-story high-rise residential, generally the issue of electromagnetic radiation needs to be considered. The high rise residential area is always open field of vision. The negative impact is that high-rise residential is always exposed to numerous radiation sources, such as base stations and television transmitting towers. The microwave radiated from these sources can directly reach high-rise buildings through free-space. Free-space attenuation of electromagnetic wave propagation is small. It always results big radiation intensity in high-rise building.
(2) When the building is close the radio and television transmission tower or other strong radiation sources, the integrated shielding design should be considered before building construction.
