Source sentences:
text: Since the production of an ion pair (usually a positive ion and a (negative) electron) requires a fixed amount of energy (for example, 33.97 eV in dry air:305), the number of ionizations per path length is proportional to the stopping power.
text: Because the number of ion pairs produced is proportional to the energy of the incident radiation, this continuously measured current is proportional to the dose rate (energy deposited per unit time) in the ionization chamber.
text: As the ionizing particle travels through the chamber it leaves a trail of ion pairs along its trajectory, the number of which is proportional to the energy of the particle if it is fully stopped within the gas.
text: By measuring the total charge (time integral of the electric current) between the electrodes, we can determine the particle's kinetic energy because the number of ion pairs created by the incident ionizing charged particle is proportional to its energy.
