Radium and Radon in the Environment

Bol

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Environmental radioactivity is the study of radioactive materials in the human environment. While some radioisotopes are only found on Earth as a result of human activity, such as Strontium-90 (90Sr) and Technetium-99 (99Tc), and some isotopes like Potassium-40 (40K) are only present due to natural processes, a few isotopes are present as a result of both natural processes and human activities e.g. tritium (3H). The concentration and location of some natural isotopes, particularly Uranium-238 (238U), can be affected by human activity.
