Hi there betty A,
You know some people here were talking some time ago, about shielding with water?
  - Using water bottles in packs stacked up on the walls  etc - and somebody said the ideal solution
would be layers of water-filled bubble-wrap? And somebody said they slept really well since they
put in water-stacks around the walls?
          I had the idea of using water last Autumn - Fall - , and I haven't done it yet. But I did
a bit of research and found out that water is much more RF and microwave -resistant if it is NOT
pure - salt water protects much better for instance . It needs to have mineral salts to protect better.
   I just though I would throw that in . One day I hope to use that idea in my home.
             The low frequencies get through, or something ,- (I'm not very scientific) - so submarines cannot pick up RF when submerged, unless they have some fantastically expensive antennae which can pick
up very low frequency transmissions, which I believe nuclear submarines are equipped with.
 I am going to use water - thanks for reminding me, best wishes, Sylvan.
