While there is no proof that the rates were different in the past than they are today, there is also no proof that they were the same.Thus radioactive dating relies purely on assumptions. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Libby received the Nobel Prize in Chemistry for his work in 1960.Alpha decay typically occurs in nuclei that are so big that they can’t be stable.In alpha decay, the nucleus ejects a helium nucleus (alpha particle) composed of two neutrons and two protons, dropping the mass of the original nucleus by four mass units.Following three forest fires in Ukraine (stock image), scientists from the Norwegian Institute for Air Research measured radiation levels in the soil and atmosphere.They discovered that these fires caused around 0.5 petabecquerels of radioactive caesium to be released over eastern Europe as smoke During 2002, 20, three forest fires swept through the region and experts from the Norwegian Institute for Air Research wanted to discover if they released any of this radiation into the air.

At Three Mile Island and Chernobyl, nuclear power plants released radioactive substances into the atmosphere during nuclear accidents.

Nuclear materials (that is, s­ubstances that emit nuclear radiation) are fairly common and have found their way into our normal vocabularies in many different ways. In this article, we will look at nuclear radiation so that you can understand exactly what it is and how it affects your life on a daily basis.

You have probably heard (and used) many of the following terms: ­All of these terms are related by the fact that they all have something to do with nuclear elements, either natural or man-made.

We thank you in advance for partnering with us in this small but significant way. All methods of radioactive dating rely on three assumptions that may not necessarily be true: It is assumed that the rate of decay has remained constant over time.
