In nuclear reactors, they are produced in the fuel (alpha decay of heavy nuclei). Alpha particles are commonly emitted by all of theheavyradioactive nuclei occurring in nature (uranium, thorium, or radium), as well as the transuranic elements (neptunium, plutonium, or americium). This is for GCS. Gamma rays are high-energy photons with very short wavelengths and thus very high frequency. They are not very penetrating, and a piece of paper can stop them. Alpha particles have the lowest penetrating power of the three types of ionising radiation. Discovery of Alpha, Beta and Gamma radiation. So, let us take a closer look at each type. The consent submitted will only be used for data processing originating from this website. I also talk about safety and otehr experiments that you can go into at A Level. Natural sources of gamma rays on Earth are, among other things, gamma rays from naturally occurring radionuclides, particularly potassium-40. Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. Radioactive decay is not affected by external conditions. Since the gamma rays are in substance only very high-energy photons, they are very penetrating matter and are thus biologically hazardous.
