Similarly, there are places in the world with higher natural radioactivity due to local geology, like Ramsar Iran with over 100 mSv/yr or Denver Colorado where cosmic rays give 2x more dose than this living at sea level. People live there just fine too. Things that are very hot are ...

Thus, the term “decay” habitual in scientific and public use is not worth treating literary to the radioactivity phenomenon, but it should be considered as a synonym of the term “transformation”. In such a sense, the terms “beta-decay”, and “gamma-decay” should be treated....
radioactive.Radioactivityis simply when very small particles in objects emit energy or smaller particles. The energy that is produced can result in cancer, serious environmental damage, or helpful technologies. There are different degrees of radioactivity, and different exposures increase the harm it ...
Radioactivity has always been present on Earth, but it was not scientifically studied until 1896. The largest source of ionizing radiation for the average American is from naturally occurring radon in the air. Without heat from naturally occurring radioactivity, the Earth’s core would have frozen ...

Chemistry, a field of science, has several branches, including nuclear chemistry. The field of nuclear chemistry is involved in the process where nuclei disintegrate or combine nucleus. The formation of a new nucleus may be natural or artificial with some processes, including radioactivity. ...

UV light is unique in that while it is non-ionizing, it does have the capacity to cause harmful effects similar to what ionizing radiation can create, such as an increased risk of cancer due to damage to DNA molecules. HOW IS RADIATION MEASURED? The radioactivity of a substance, or how ...
