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.
One of the advantages of this method is that any sample provides two clocks, one based on uranium-235's decay to lead-207 with a half-life of about 703 million years, and one based on uranium-238's decay to lead-206 with a half-life of about 4.5 billion years, providing a built-in crosscheck that allows accurate determination of the age of the ...
Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
“A moment on the lips, a half life on the hips.” 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.

When asked if he would eat a cookie off a plate made of uranium glass, Dr. Frame answered "I have," and reminisced about a dinner party he went to were the entire meal was served on the stuff ...
Most decay quickly but can still be observed astronomically and can play a part in understanding astronomic processes. Primordial radionuclides, such as uranium and thorium , exist in the present time because their half-lives are so long (>100 million years) that they have not yet completely decayed.
When that happens, the fish immediately release venom into whatever disturbed it. Effects are fast acting and can include heart stoppage, seizures, and paralysis. Number 8.Cleaning the toilet. No ...
