Because enriched uranium is a radioactive substance, there has been concern about the possible health effects of depleted uranium. While depleted uranium does not have the level of radioactivity of enriched uranium, some experts fear that itmight cause health problems. The Department of Defense and ...
These embryos rotated around the Sun, but they did not stay on safe, circular orbital paths for long. The gravitational attraction among them soon forced the issue. The embryos' orbits became more elliptical (egg shaped), and their paths began to cross-and so they began to collide, not ge...
For example, when radioactive elements like uranium, radium and polonium decay, they release radioactive alpha particles. These particles, made up of protons and neutrons, are large and can only travel a short distance -- in fact, they can be stopped with just a piece of paper or even ...
A bottom rating indicates the company is involved in the design, construction or operation of nuclear power stations, radioactive waste handling and/or the mining, processing, or reprocessing of uranium. It also may indicate the production of other nuclear-related equipment, such as monitoring facil...

U-238 is a radioactive metal that produces alpha and beta particles. In its solid form, it is not particularly dangerous because its half-life is 4.5 billion years, meaning that the atomic decay is very slow. Depleted uranium is used, for example, in boats and airplanes as ballast. The ...

Odd though it might seem, there's a long tradition of amateur "radiation hunting." In my 2015 book Atoms Under the Floorboards (p.106), I reprised the story of how amateur uranium prospectors used to sneak out with their Geiger counters, under cover of darkness, to try to find lucrati...
