With its relatively long half-life (t1/2 = 10.6 h) and low energy -emission (239 KeV), 212Pb is suitable for gamma scintigraphy in respiratory tract deposition studies. As a decay product of 212Rn in pure air, the 212Pb particles are in the size range of 12 nm. An evaporation/...

An isotopic theranostic match can be found in 203Pb, which has a half-life of 2.1 d and is suitable for SPECT imaging. Because of the pair's suitable chemical and physical properties, 203Pb and 212Pb are ideal for clinical translation (6). However, with a relatively short physical half-...
An isomer of Po212 with a half life of (45.l±0.6)sec and an excitation energy of 2.93 Mev has been positively identified by chemical and nuclear spectroscopic techniQues. The isomer decays to known states of Pb208 by the emission of alp... I Perlman,F Asaro,A Ghiorso,... - 《Physi...
Consequently, clearance from the tumor was slower for [212Pb]Pb-eSOMA-01 than [212Pb]Pb-eSOMA-02 (half-life of 18.9 ± 6.1 h vs. 9.3 ± 4.2 h, respectively; NS), but faster than [212Pb]Pb-DOTAM-TATE (half-life of 37.1 ± 29.6 h) (Figure 6). Efficient blockage of the ...
Due to the longer half-life of 203Pb, the stability of [203Pb]Pb-PSC-PEG-T could be monitored up to 72 h, whereas the stability of [212Bi]Bi-PSC-PEG-T was monitored for 5 h, accounting for five half-lives of 212Bi. More than 99% of 203Pb remained in PSC-PEG-T with less ...
Pb is an attractive isotope for medical applications because it is has a short half-life (10.64h), and one of its decay products (Po) emits a very high LET alpha-particle (=8.78MeV). Radiolabeled trastuzumab was found to be pure, functional, and intact by both ELISA and SDS-PAGE ...

The released 212Bi with 60 min half-life can redistribute in the circulation and accumulate mainly in kidneys. Therefore, continued interest exists in developing a bifunctional chelation agent for sequestering 212Pb in targeted alpha particle therapy. The chelation agent should withstand the beta decay...
However, with a relatively short physical half-life (10.6h), 212Pb-bearing radiopharmaceuticals require fast pharmacokinetics. Thus, pretargeted radionuclide therapy (PRT) is an especially promising strategy for using 212Pb (7).Download figureOpen in new tabDownload powerpointFIGURE 1. Pretargeting ...
