Why is a GM counter not useful for determining the absorbed energy in a gas?

A GM counter, or Geiger-Muller counter, is primarily used for detecting and measuring ionizing radiation. It works by detecting the ionization of gas molecules in a chamber, which is then converted into an electrical signal. However, it is not sensitive to non-ionizing radiation, such as the energy absorbed by gas molecules. Therefore, it is not an appropriate tool for measuring gas absorbed energy.
Ionizing radiation has enough energy to remove electrons from atoms or molecules, creating ions. This type of radiation includes gamma rays, X-rays, and particles such as alpha and beta particles. Non-ionizing radiation, on the other hand, does not have enough energy to create ions. This includes radio waves, microwaves, and infrared and ultraviolet light.
No, a GM counter is only useful for measuring ionizing radiation. It is not sensitive to non-ionizing radiation, such as the energy absorbed by gas molecules.
One method for measuring gas absorbed energy is through the use of a calorimeter. This instrument measures the temperature change of a gas when it absorbs energy. Another method is spectroscopy, which uses the absorption of specific wavelengths of light to determine the energy absorbed by gas molecules.
In general, a GM counter is not a suitable tool for measuring gas absorbed energy. However, in some cases, it may provide a rough estimation of absorbed energy if the gas is being exposed to high levels of ionizing radiation. This is because the ionization of gas molecules can indirectly indicate the amount of energy absorbed by the gas.
