What is meant by ionising radiation?

Answer 1

See the Wikipedia article 'Ionising Radiation' of which this is the introduction. Ionizing radiation consists of subatomic particles or waves that are energetic enough to detach (ionize) electrons from atoms or molecules. Ionizing ability depends on the energy of the impinging individual particles or waves, and not on their number. A large flood of particles or waves will not cause ionization if these particles or waves do not carry enough energy to be ionizing. Examples of ionizing particles are energetic alpha particles, beta particles, and neutrons. The ability of electromagnetic waves (photons) to ionize an atom or molecule depends on their wavelength. Radiation on the short wavelength end of the electromagnetic spectrum - ultraviolet, x-rays, and gamma rays - is ionizing.

Answer 2

Ionizing radiation is a type of radiation that carries enough energy to remove electrons from atoms or molecules, leading to the formation of ions. This process can damage biological tissues, DNA, and other molecules, and has the potential to cause mutations and increase the risk of cancer. Examples of ionizing radiation include X-rays, gamma rays, and some types of ultraviolet light.

Answer 3

It is the radiation that ionizes the air or the medium when passing through
