How does a Geiger counter measure radiation levels?
Radiation is absorbed by gas atoms, which undergo phosphorescence and emit a different radiation.
Radiation is absorbed by gas atoms, which undergo nuclear reactions and emit a different radiation.
Radiation knocks neutrons out of gas atoms, which causes the gas atoms to become unstable.
Radiation knocks electrons out of gas atoms, which allows the gas to conduct an electric current.

Respuesta :

Radiation is absorbed by gas atoms, which undergo nuclear reactions and emit different radiation. Hence, option B is correct.

What are Geiger Counters?

A Geiger counter (Geiger-Muller tube) is a device used for the detection and measurement of all types of radiation: alpha, beta and gamma radiation.

A Geiger counter exploits the natural process of ionization to detect and measure radiation. The device houses a stable gas within its chamber. When exposed to radioactive particles, this gas ionizes. This generates an electrical current that the counter records over a period of 60 seconds.

Hence, option B is correct.
