Will a faraday cage stop gamma rays?

[indio007]

Can a faraday cage be used to stop the radiation at the Japanese reactor? If not why not? I know the frequencty is high but what if you pulsed DC current at the same frequency would that stop it?

Faraday cages work on radio/microwaves. X-rays and gamma rays penetrate matter.

I suggest one determine the frequencies of 10 keV, 100 keV, 1 MeV photons.

When it comes to stopping high energy electromagnetic radiation there is little better than thickness and/or density - concrete and lead come to mind as suitable substances. Lead has the density but also produces high energy compton recoil electrons that can subsequently lose energy via Bremsstrahlung radiation.
