Gamma ray High-energy electromagnetic

Gamma rays High-energy electromagnetic radiation. It is the most penetrating form of radiation that results from the decay of radioactive elements.

Gamma rays—High-energy electromagnetic radiation emitted by certain radionuclides when their nuclei transition from a higher to a lower energy state, very similar to x-rays. 

Alpha particles Positively charged particles identical to helium-4 nuclei emitted by certain radioactive isotopes Beta particles Electrons ejected at high speeds from certain radioactive isotopes Gamma rays Eligh-energy electromagnetic radiation emitted from radioactive isotopes... 

Gamma rays are high energy electromagnetic radiation with very short wavelengths (10"111 to 10 11 cm). They penetrate matter deeply—on Ihe average much more deeply Ilian do alpha and beta rays, which arc charged... 

Gamma rays are high-energy electromagnetic radiation, and gamma radiation is almost always emitted when other radioactive decay occurs. Gamma rays usually aren t written into equations because neither the mass number nor the atomic number is altered. One exception is the annihilation of an electron by a positron, an event that only produces gamma radiation ...
