    Why cant rads be converted to cpm?

    hi, i have a geiger counter which measures radiation in rads, but not many people use rads anymore (it is almost obselete i think), am i correct it saying that rads are a measure of the number of particles being emitted AND the energy of the particle, but cpm is merely a measure of the...
