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 ... leaves mass number and atomic number unchanged; gamma rays produce the least ionization.

We know that regular supernovas pose no existential threat to life on Earth in the near-term. But there are other varieties of supernova that are a little bit harder to predict, and a little bit ...

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 ...
