Strong H fields: electronic items susceptible to thier damaging effects and how to shield them
An H-field changing at 36 MHz will induce a 36 MHz current in your copper foil. 

Maxwell's equations plus Stokes give you

$$ \oint_{\partial \Sigma} \mathbf{E} \cdot d\mathbf{l} = -\mu\int_\Sigma \frac{\partial \mathbf{H}}{\partial t} \cdot d\mathbf{A} $$

I.e. the electric field integrated along a  contour \$\Sigma\$ (which gives you a potential) is the integral of the time-derivative of your H-field times your medium's \$\mu\$. At 130 A/m, and remembering that derivative of \$\sin(ft)=f\cos(ft)\$, that's bad news for your copper, and for the things it protects. The induced currents will be high enough to fill the whole couple of microns of thickness, and will couple into the things you wanted to protect.
