Thorium Decay Chain

the uranium decay chain - it's not just an alpha emitter!

this video is about uranium ore, pitchblende - and the natural (radio-)isotope mix that comes with it. uranium is indeed an alpha emitter - but don't be fooled, this is not the only radiation emitted by uranium ore! there are alpha and beta particles, gamma rays, and even neutrons...

finding uranium in nature

uranium minerals. =) the radioactive minerals i found are uranocircite and autunite. they now have a new caring and loving home at my place. ps: i know it's not just uranium in there but a lot of other radionuclides that are within the decay chain, as well as the endproduct - stable lead. i just called it all 'uranium' for simplicity. :-) MUSIC: KRAFTWERK - RADIOACTIVITY www.kraftwerk.de ... atom uranium mine nuclear mineral collection physics radioactive radioaktiv radioactivity decay ...

a closer look at americium 241 from a smoke detector

in this video, i disassembled a smoke detector to show you the properties of americium 241, the second nuclide in the neptunium decay chain. yeah i know i used some 'wrong' words, ie. could've used more fitting words to describe stuff at times, but i did this freestyle and being rather tired - hope you like it anyway, even with the mobile phone annoyances inbetween, too. ;-) also, there's four major decay chains, but only three naturally radioactive ones - neptunium is the artifical one. ...

Oops. Wrong decay products =X

Watch this video. I made a pretty critical error when writing the decay chain and felt it needed to be fixed.

th

Iodide process) was discovered by Anton Eduard van Arkel and Jan Hendrik de Boer in 1925 to produce high-purity metallic thorium.[4] The name ionium was given early in the study of radioactive elements to the 230Th isotope produced in the decay chain of 238U before it was realized that ionium and thorium were chemically identical. The symbol Io was used for this supposed element. Thorium is found in small amounts in most rocks and soils, where it is about three times more abundant than uranium ...
