ionise

Approximately 36 eV of energy is required in the production of one ion pair thus a proton with 10 MeV initial energy is able to ionise about 280,000 molecules along its path before all the energy is lost.

In addition to the primary protons, the secondary electrons produced in ionisation may have enough energy to further ionise and dissociate atmospheric gases.

This means that they are best at detecting alpha particles, because a-particles ionise strongly.

A charged particle passing through the gas-filled tube will ionise the gas.

They then have enough energy to ionise the gas and more electrons are liberated, which in their turn are accelerated and so on.

More electrons are liberated which in their turn ionise the gas – an avalanche of charges is produced, giving rise to an electric pulse on the anode wire.

The rays from radium compounds discharge electrified bodies, ionise gases, that is, cause them to conduct electricity, act on photographic plates, and produce profound changes in living organisms.

It may be that the liberated electrons ionise molecules not directly affected, or it may be that in their liberation they disrupt complex molecules built up in the ripening of the

Helium which is chemically one of the most inert of the elements, is, when possessed of such great kinetic energy, able to penetrate and ionise the atoms which it meets in its path.

Its either an optical one used mostly in factories, using infra red beam and sensing break in beam by smoke particles or ionising used in houses very sensitive. uses very small radioactive material to ionise the air, and sensing smoke which changes the resistance
