Answer:
alfa, beta and gamma
Step-by-step explanation:
Rutherford studied the three types of radiation.c In the case of alpha radiation, it is composed of two protons and two neutrons, the alpha particle is a nucleus of the element helium, which has high mass and short range.
In the case of beta radiation, it travels distances of up to one meter and consists mainly of electrons.
In the case of gamma radiation, it is composed of high-energy photons (it does not have my electrical charge or resting mass).
