The reasons for this are;1) it is a strong beta emitter (Emax = 1.86 MeV) with maximum range insoft-tissue of 8.4mm,2) it has a short physical half-life of 26.9 hours,3) it emits a gamma photon (81 keV, 5.4 percent) that can be used forexternal imaging of post-therapy ...
half-lifeholmium 166WHEN the element holmium is irradiated with slow neutrons the radioactive isotope holmium-166 is produced. This decays by β-emission to the stable isotope of erbium, Er.doi:10.1038/163524b0GRANT, P. JHILL, J. M
Holmium-166m has a long half life (1200 yr) and emits a large number of γ-rays between 80 and 1400 keV. These characteristics are very suitable for γ-ray... Y Hino,S Matui,T Yamada,... - 《Applied Radiation & Isotopes》 被引量: 21发表: 2000年 加载更多来源...
被引量: 166发表: 2002年 Synthesis and characterization of heterometallic M-Ru (M = Co, Rh, Ir) clusters containing the nido-dicarborane-1,2-dithiolato chelating ligand. The 16-electron half-sandwich complexes Cp*M[S2C2(B10H10)] (M = Ir (1), Rh (2), Co (3)) react with [Ru(CO...
Ho has a 100% natural abundance of holmium-165, which is a stable nuclide that can undergo a process called neutron-activation to generate radioactive holmium-166 (Ho). Ho emits β–particles and γ photons, with a half-life of 26.8 h; β–particles can damage a cancer cell's DNA, ...
Moreover, unlike traditional SIRT devices based on yttrium-90, Ho-166 microspheres can be imaged in vivo by both SPECT and MRI, providing improved treatment planning. Unfortunately, this therapy is only currently available in Europe due to the short half-life of the Ho-166 and the thermally ...
The compound disclosed preferably has a particle size of 1 to 40 microns, Beta energy emissions in the range of 1.76-1.84 MeV, low levels of gamma ray emissions and a radioactive half-life of 26.8 hours. The preferred metallic hydroxide is selected from the group consisting of Ferric ...
Conclusions The use of Ho-166 for RSO is effective and safer than Y-90. The shorter half life of 26.9 hr. for Ho-166, the less amount of leakage results in a smaller radiation burden or the whole-body. Becouse of the physical characteristics Ho-166 can be used for large (knee) and...
Most stable technogenic radionuclide 163 Ho (half-life 4570 years). The most common compounds: Ho 2 O 3 , HoF 3 , and Ho(OH) 3 . Biologically, holmium is of low to moderate toxicity, can inhibit activity of reticuloendothelial system after intravenous infusion (Atkins et al. 2006 ; ...
half-lifeholmium 166measured valuesThe decay of long-lived 146Ho is discussed and results are given which suggest that the 817 and 718 kev -rays are each in competition with separate cascade pairs of energies 537 + 280 kev and 438 + 280 kev respectively. A level scheme is proposed ...
