monitor radiation suggestions

[Speelgoedmannetje]

Tis not really Amiga specific, but I got this question:
I got on one desk three computers, my PC, my C=64 and my A500. All of them got their own monitor. I don't have the space to put those monitors further away from each other. If I turn two or three monitors on at the same time the picture on these monitors get very distorted. Probably I need to put some radiation absorbing material between these monitors, but I don't know what and how. Anyone has experience with this and wants to share their suggestions?

They're OLD
I mean, I got one very good Philips 17" flat screen monitor for my pc, but the C=64 monitor is an completely analog one, and the Amiga monitor is a 1084S, and I do not have the money to buy new monitors for these vintage computers.

Does it make sense, if I put metal/lead panels between the monitors, and connecting these somehow to ground?

Thank you all very much for your advice :-)
I got a clear view now what to be done about it
(though TFT is still a bit too expensive for me :-( :-))
