Which of the following instruments is used for measuring radiation?1. Geiger-counter 2. Carburettor3. Calliper4. Galvanometer

Answer» Correct Answer - Option 1 : Geiger-counter 

The correct answer is Geiger-counter.

  • Geiger-counter is the most common instrument for measuring radiation.
  • For detecting and measuring radiation, many laboratory instruments are used.

  • Human senses cannot detect radiation.
  • In Geiger-counter, electric pulses are created when a high voltage is applied.
  • These pulses give the reading on the instrument.
  • Micrometre with sodium iodide detector is also used for measuring radiation.
  • In this, the electric signal is produced by pulse and light.

  • A portable multichannel analyser is also used to detect radioactive materials.
  • The ionisation chamber is also used to detect radiation.
  • Neutron REM metre is also used to detect radiation.
