D.alpha and beta particles as they strike a detector window.
E.flashes of light emitted from a phosphor affected by radiation.
Explanation / Answer
A Geiger counter measures radiation by detecting
Correct Answer:
C. electrons released when gas atoms are ionized by the radiation.
A Geiger counter, measured the radiation when the radiation collides with gas molecules it causes ionization, producing positive ions and electrons. The electrons are detected by the Geiger counter.
