Uranium decay chain products, animation

Référence de la vidéo 12939038
Uranium decay chain products with half-lives, animation. The radioactive isotope uranium-238 decays by the breakdown of its unstable nucleus, . The products are a succession of other radioactive isotopes, culminating in the stable isotope lead-206. The particles in the nucleus are protons (red) and neutrons (yellow). Three types of radiation are produced: beta particles (electrons, blue), gamma radiation (orange) and alpha particles (red and yellow). The first decay produces thorium-234. The next decay produces proactinium-234, followed by uranium-234, thorium-230, radium-226, radon-222 and polonium-218. Subsequent decays produce isotopes such as astatine-218, lead-214, bismuth-214, thallium-210, polonium-214, lead-210, mercury-206, bismuth-210 , thallium-206 and finally lead-206. This is known as the radium series (also called the uranium series). For animations of the decay chain, see clip K008/5467 and K008/5468.
