a detector that can react to beta radiation will also react to gamma radiation, a shielded detector allows you to get a gamma reading, then open a window, and get a beta plus gamma reading - subtracting the shielded number then gives you the beta radiation intensity. (gamma is a high energy penetrating electromagnetic wave, while beta is a high energy electron, that can't penetrate much at all. (your skin would stop beta from an external source, however it would reach the living cell layer in your skin or eyes, so beta exposure should be also treated ALARA (as low as reasonably achievable)..

Does not compute . Beta particles is just free electrons . They cause ionization.
