Will there be radiation outside the darkroom for testing the antenna efficiency of mobile phones?

Hey hey, what do you say? A darkroom is a shielded room. Simply put, after the door is closed, the signal outside can't get in and the signal inside can't get out.

However, the door of the darkroom is almost always open, right? So there is still radiation.

Also, where did the radiation signal from the darkroom come from? Didn't that 8960 outside get in? As long as you are exposed to these microwave devices, how can you not be irradiated?

The field strength from the antenna of an external base station to the ground is generally around -60dB~-90dB.
