Radon (Rn-222) is a radioactive gas in the uranium series. Radon is produced from uranium (U-238) through a series of decay steps. The element preceding

Task. Uranium 238 is a radioactive material with many applications in nuclear technology. It decays exponentially with a half-life of about 4.5 billion years.

Some of the other isotopes have been detected in nature, originating from trace quantities of 237 Np produced by the (n,2n) knockout reaction in primordial 238 U. A smoke detector containing an americium-241 ionization chamber accumulates a significant amount of neptunium-237 as its americium decays; the following elements are also present in it, at least transiently, as decay products of the neptunium: actinium, astatine, bismuth, francium, lead, polonium, protactinium, radium, thallium

238 U. 238 U decays via alpha decay to 234 Th with half-life of ~4.5×10 9 years. 238 U occasionally decays by spontaneous fission with probability of 0.000055%. Its specific activity is very low ~3.4×10-7 Ci/g.
