The elevator is separated from the room by a wall. Will it have any effect on people's health? Will there be radiation or something?

As far as radiation is concerned, there is no case of elevator radiation exceeding the standard in China. Don't worry, the main problem is noise. I don't know what floor you are on. If you are on the top floor, the noise will affect you, but some better development companies will soundproof the computer room. If you are on other floors, there is no problem at all, because the computer room on the top floor is too far away from you, and only the elevator car stops at your door.
