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.
