toron — Engelska översättning - TechDico

"thoron" means the radionuclide Rn-220 and its progeny, as appropriate; Inglese. Total β: except 40K, tritium and short-lived radon decay products. Det är 220Rn (från sönderfallskedjan 232Th, se fråga 13744 ) som sönderfaller till 216Po. Det finns en sönderfallskalkylator på Universal Decay Calculator . It also point out that decay products of radon, namely polonium-. 210 and 220.

In contrast, substantially less 220 Rn reaches the atmosphere because its short half-life (55.6 s) limits the distance it can travel before decay. As for 219 Rn (formed in the decay chain of 235 U), it may be ignored entirely because of its short half-life (3.96 s) and the comparative scarcity of 235 U. Write A Series Rn Partial For 220 Decay. Most radioisotopes do not decay directly to a stable state, but rather undergo a series of decays until eventually a stable isotope is reached Decay stages are referred to by their. (II and VA )..

1956-04-01 The gas thoron, or thorium emanation, is an isotope of radon (86 Rn 220) which decays by α emission and has a half life of 55.6 seconds. 2 Using an emanation electroscope, we observe the radioactive decay of thoron (separated from all its parent substances) by the progressive decrease of ionization in the air around the thoron.
