[ RadSafe ] Re: Radiation deficiency remediation: KCl

[John Jacobus]

A mattress will not reduce the photon radiation that
much, as the energies are 1.4 MeV.  All you would
loose is the beta emissions from the surface you sleep
on.  The beta emissions would contribute to a shallow
dose on the side in contact with the bags.

Let me know if the additional radiation improves your
health beyond the placebo effect.  Maybe it will
offset not sleeping on a mattress.
