Aluminum foil will stop beta radiation (and look how thin it is). Fast electrons are not very penetrating which may go some way toward explaining why Rossi said that you could detect radiation in some places but not others, and he provided a hole for the detector where he thought some would be detected, but not too much. OTOH fast electrons will create X-rays, with the outliers in the bremsstrahlung having an energy equal to the maximum electron energy. Nevertheless, only about 1% of fast electrons create x-rays, and many of these will have energy considerably less than the maximum. That could be what the lead shielding is for. Note also that any solid or liquid will stop fast electrons, including copper, stainless steel, Nickel powder, and water. Most of the energy ends up as heat. These substances will also absorb some of the x-rays. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
