No, it cannot. Alpha particles can be stopped using aluminum foil. Beta particles (electrons) posses higher kinetic energy and have smaller cross section. Lead is widely used to stop beta particles as well as gamma particles. Gamma particles are basically high energy photons which are extremely dangerous for alive creatures. Extra precaution must be taken when you are working with such radiation.
