Natural radioactivity includes cosmic radiation, earth radiation, and radiation from materials in the human body. Cosmic radiation creates subatomic particles and radioactive isotopes, including carbon-14 used in radiocarbon dating. Terrestrial radiation comes from isotopes of carbon, potassium, thorium, and uranium found in soil, rocks, and water. The human body also contains radioactive isotopes from terrestrial […]
Radioactivity is the process where unstable atomic nuclei release energetic subatomic particles or electromagnetic radiation. It can transform elements and is used in nuclear energy, medicine, and dating specimens. Radioactive decay is a random process quantified by half-life. Types of decay include alpha, beta, and gamma. Radioactivity is used in nuclear power plants, weapons, medicine, […]
