Q: Device used for the detection and measurement of all types of radiation (alpha, beta and gamma)
  • A. Geiger Counter
  • B. Polarimeter
  • C. Calorimeter
  • D. Radiometer
Correct Answer: Option A - A Geiger muller counter is a device used for the detection and measurement of all types of radiation : Alpha, beta and gamma radiation. Basically it consists of a pair of electrodes surrounded by a gas. The electrodes have a high voltage across them. The gas used is usually Helium or Argon. It is the world's most capable and used radiation measuring instrument.
