The thicker the substance, the more the radiation is absorbed. Alpha, beta and gamma radiations penetrate materials in different ways. Alpha radiation is the least penetrating. It can be stopped ...

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.

and that the pulse-height is proportional to the energy of the alpha-particles. It is found in studying the pulses for some beta-radiating substances that there is proportionality between pulse ...

On May 12, 1957, a new Greek organization emerged among a growing Hope College: Alpha Gamma Phi. The name originated from the Greek words for Anchor, Stability, and Faith. Friendship is the ...

TAT is a form of radiotherapy that involves drugs labeled with alpha particle-emitting radioisotopes. Compared to other forms of radioactive emissions (beta and gamma emissions), alpha particles ...
