Potassium-40 (up to 88% of total activity), carbon-14 (14 C), radium-226, uranium-238 and rubidium-87 (87 Rb) are found in ocean waters. Moreover, in groundwater abound radius radioisotopes such as radium-226 and radium-228 (228 Ra). [7] [8] They are also habitual in building materials radionuclides of uranium, thorium and potassium (the latter ...
Uranium in the environment is a global health concern, and comes from both natural and man-made sources. Beyond naturally occurring uranium, mining, phosphates in agriculture, weapons manufacturing, and nuclear power are anthropogenic sources of uranium in the environment. [1]
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
The blowfish, if not prepared absolutely flawlessly, can kill upon consumption. Just one of them packs enough tetrodotoxin to wipe out 30 people. More from AOL.com:
Did a Tri-Cities scientist eat radioactive uranium in the ‘80s to prove that it is harmless?. Maybe, says a recent new fact check by Snopes.com. Galen Winsor was a Richland nuclear chemist who ...

Unprotected experiments in the U.S. in 1896 with an early X-ray tube (Crookes tube), when the dangers of radiation were largely unknown.[1]The history of radiation protection begins at the turn of the 19th and 20th centuries with the realization that ionizing radiation from natural and artificial sources can have harmful effects on living organisms.
a protective internal shield (usually uranium metal or a tungsten alloy), and a cylinder of radioactive source material ( caesium-137 in the Goiânia incident, but usually cobalt-60 ) The Goiânia accident [ɡojˈjɐniɐ] was a radioactive contamination accident that occurred on September 13, 1987, in Goiânia , Goiás , Brazil, after an ...
