A method and generator for preparing the radioisotope of lead, 212Pb, whereby 228Th, in a closed chamber, is allowed to decay to gaseous 220Rn which is then readily separated from the thorium and other decay products by diffusing the 220Rn gas into a second chamber, where it decays to ...
212Pb is differentiated as both an alpha and beta-emitting isotope with a simple decay chain that has demonstrated promising clinical results1in compassionate use and phase 1 settings.212Pb is produced via a generator using thorium (228Th, 1.9 year half-life) or...

(Supplementary Fig.14), and this is accompanied by a longer PL decay lifetime (Supplementary Fig.15) compared to the control device. We also fabricated electron-only and hole-only devices to study the origins of carrier trapping in perovskite films. SCLC reveals that electron traps are ...
The decay of U and Th to stable isotopes of Pb is the basis for several important geochemical methods of dating. Two radioactive isotopes 210 Pb ( t 1/2 = 22 years) and 212 Pb ( t 1/2 = 10 h) are used in tracer experiments. Lead exists mostly in the oxidation state +2. ...
Good agreement between the absolute reduced widths determined from α-transfer and α-decay suggests that in the transfer reactions, as in α-decay, an α-particle in its ground state is transferred in a one-step process. 展开 关键词: Nuclear reactions ...
