Question

Can an electron lose all of its kinetic energy due to radiation

Answer 1

Ionization is the process of liberating an electron from the electron cloud of an atom exposed to ionizing radiation. ... Ionizing particles with certain kinetic energy lose this energy over their trajectory due to the interaction withthe electron cloud of the absorbent element.

Answer 2

the newly produced electrons and positrons then continue to lose their kinetic energies through the process of ionization and exication of the surrounding atoms. when the positron lower its energy all the way down to values corresponding to the speed of thermal motion it can be merged with the random electron
