First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The transmission resonance model (TRM) is combined with some electrochemistry of the cathode surface and found to provide a good fit to new data on excess heat. For the first time, a model for cold fusion not only fits calorimetric data but also predicts optimal trigger points. This suggests that the model is meaningful and that the excess heat phenomenon claimed by Fleischmann and Pons is genuine. A crucial role is suggested for the overpotential and, in particular, for the concentration overpotential, i.e., the hydrogen overvoltage. Self-similar geometry, or scale invariance, i.e., a fractal nature, is revealed by the relative excess power function. Heat bursts are predicted with a scale invariance in time, suggesting a possible link between the TRM and chaos theory. The model describes a near-surface phenomenon with an estimated excess power yield of ∼1 kW/cm3 Pd, as compared to 50 W/cm3 of reactor core for a good fission reactor. Transmission resonance-induced nuclear transmutation, a new type of nuclear reaction, is strongly suggested with two types emphasized: transmission resonance-induced neutron transfer reactions yielding essentially the same end result as Teller's hypothesized catalytic neutron transfer and a three-body reaction promoted by standing de Broglie waves. The cross section σ for the nuclear reaction that is the ultimate source of the excess heat is estimated to satisfy 10−28 cm2 ≲ σ ≲ 10−18 cm2. Suggestions for the anomalous production of heat, particles, and radiation are given. A polarization conjecture leads to a derivation of a branching ratio of 1.64 × 10−9 for the deuterium-deuterium reaction in electrolytic cold fusion in favor of tritium over neutrons. The model may account for the Bockris curve, in which a lower level production of tritium mirrors that of excess heat. Heat production without tritium is also accounted for, as well as the possibility of tritium production without heat. Thus, the TRM has a high probability for unifying most, if not all, of the seemingly anomalous effects associated with cold fusion.
