A device used for the measurement of radioactivity is

  • A.Mass spectrometer
  • B.Cyclotron
  • C.Nuclear reactor
  • D.G.m.counter

Answer: D

Radioactivity is measured with a Geiger–Müller counter.

Radiation entering the tube ionises the gas inside; the ions are accelerated by a high potential difference and produce an avalanche that registers as a pulse. Each pulse is one detected particle, so the count rate measures the activity.
