The "box" I do lay my PP on is directly under my computer about three inches below it. (I have my computer on a small wire shelf)

I don't know about RF as I do not use wireless on this computer, it is direct connect broadband.

But every little bit of information helps.....
Floppies were/are sensitive to magnetic fields. That brownish layer is Iron oxide that is recorded tiny magnetic bits. Any alternating current field really close will slowly rearrange the bits. A strong magnet will do it NOW.
Color CRT used a Very strong magnetic loop around the edge of the CRT that comes on for a few seconds when you powered the CRT up (or chose: Degauss) to Keep the CRT face magnetically neutral .

LCD's do NOT need this technique.
