if you are concerned about bluetooth and wifi radiation (actually our environment is constantly bombarded with any other form of radiation, we just dont know or notice it), change your RPi3B (or RPi3B+) to RPi2B v1.2. That model has no WiFi or bluetooth, but carries the same SoC as RPi3B.
The WiFi and bluetooth in RPi3B and later models can be turned off (IIRC) via config.txt.
TV emits radiation, the lightbulb emits radiation, the microwave oven uses radiation, etc, and of course, our sun emits radiation...
the only place where radiation may not penerate is in a sealed lead box covered by a faraday cage... housed in a thick concrete bunker....
