“…Beta sensitivity and background corrections were made by inserting, between source and crystal, 15 mg cm-2 foil sufficient to absorb the 8.8 MeV alpha rays. The resulting value for the branching ratio c(/(tl+fl) = 0.36&0-01 is in good agreement with the values of Rice Evans andFreeman (1958), Senftle, Farley andLazar (1956) and Schupp, Daniel, Eakins and Jenson (1960).…”

“…Emery and Kane (1960) have examined the external photoelectron spectra from a radiothorium source. Schupp, Daniel, Eakins and Jensen (1960) in an admirably comprehensive study have used beta spectra together with double and triple coincidence techniques. The present results, while without the scope and accuracy of these experiments, nevertheless give support to some of their findings.…”

The decay of ThC (212Bi) to ThC' (212Po) has been studied by coincidence techniques and those gamma radiations emitted from the 21zPo nucleus have been distinguished from other gamma rays in the thorium decay series. An estimate of intensities has enabled the assignment of multipole orders to some transitions. The branching ratio of 212Bi and the half-life of the ground state of 212Po were re-measured.

“…The parameters of the 212 Pb-SSTA-PBPK model are classified into mice-specific and 212 Pb-SSTA-specific parameters with values taken from literature (Supplementary Material Table S1) [4,16,[22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Briefly, the main mice-specific parameters considered in the model are blood flow, tissue volumes, relevant volumes of tissue compartments (vascular, interstitial, early endosomes and sorting (late endosomes) compartments) and SSTR2 expression on cell membranes.…”

A Physiologically Based Pharmacokinetic Model for In Vivo Alpha Particle Generators Targeting Neuroendocrine Tumors in Mice

et al. 2021

In vivo alpha particle generators have great potential for the treatment of neuroendocrine tumors in alpha-emitter-based peptide receptor radionuclide therapy (α-PRRT). Quantitative pharmacokinetic analyses of the in vivo alpha particle generator and its radioactive decay products are required to address concerns about the efficacy and safety of α-PRRT. A murine whole-body physiologically based pharmacokinetic (PBPK) model was developed for 212Pb-labeled somatostatin analogs (212Pb-SSTA). The model describes pharmacokinetics of 212Pb-SSTA and its decay products, including specific and non-specific glomerular and tubular uptake. Absorbed dose coefficients (ADC) were calculated for bound and unbound radiolabeled SSTA and its decay products. Kidneys received the highest ADC (134 Gy/MBq) among non-target tissues. The alpha-emitting 212Po contributes more than 50% to absorbed doses in most tissues. Using this model, it is demonstrated that α-PRRT based on 212Pb-SSTA results in lower absorbed doses in non-target tissue than α-PRRT based on 212Bi-SSTA for a given kidneys absorbed dose. In both approaches, the energies released in the glomeruli and proximal tubules account for 54% and 46%, respectively, of the total energy absorbed in kidneys. The 212Pb-SSTA-PBPK model accelerates the translation from bench to bedside by enabling better experimental design and by improving the understanding of the underlying mechanisms.

“…High-energy gammaradiation of 232 U is emitted by its decay products; 232 U decays with a 69 year half-life through 1.9 year half-life 228 Th to 208 Tl, which emits a 2.6 MeV gamma ray upon decay. After 2 years of decay 208 Tl accounts for about 85% of the total dose [Schupp 1960;Sampson 2001].…”
