Beta particles have a higher penetration power than alpha particles and can easily ... electromagnetic spectrum have no mass known as gamma rays. Gamma rays and X-rays are high-energy waves ...

This radiation received its name — gamma-rays — simply because gamma is the third letter in the Greek alphabet after alpha and beta. Unbeknownst to Villard and his cohorts in the early 1900s ...

After emitting an alpha or beta particle, the nucleus will often ... leaves mass number and atomic number unchanged; gamma rays produce the least ionization.

Further research by scientists like Ernest Rutherford categorized radioactive emissions into alpha, beta, and gamma rays, leading to the understanding of radioactive decay and the concept of half ...

Broser and Kallmann 1 have shown that mono-energetic alpha-particles give pulses of ... obtained when studying the pulse-height from the gamma-rays emitted by different substances.

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.
