WebJun 14, 2024 · 1. It is commonly taught that alpha particles have high ionising ability and low penetrating ability (explained by saying due to their large charge and kinetic energy, they are able to knock off electrons of atoms during a collision). However, what I do not understand is why do gamma radiation does not have a high ionising ability. A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 25 and 140 Hz, the 40 Hz point being of particular interest. Gamma rhythms are correlated with large scale brain network activity and cognitive phenomena such as working memory, attention, and perceptual grouping, and can be increased in amplitude via meditation or neurostimulation. …
