The third type of ionizing radiation includes gamma and X rays, which are electromagnetic, indirectly ionizing radiation. These are indirectly ionizing because they are electrically neutral (as are all
Do gamma rays Ionise?
Gamma radiation is highly penetrating and interacts with matter through ionisation via three processes; photoelectric effect, Compton scattering or pair production. Due to their high penetration power, the impact of gamma radiation can occur throughout a body, they are however less ionising than alpha particles.
Do gamma rays refract?
What they discovered is that the energy of the gamma rays increased the falling refraction values, and then suddenly started to increase to larger positive refraction values similar to that of visible light. These were much higher values than anyone expected.
