Four terbium radioisotopes (149, 152, 155, 161Tb) constitute a potential theranostic quartet for cancer treatment but require any derived radiopharmaceutical to be essentially free of impurities. Terbium-155 prepared by proton irradiation and on-line mass separation at the CERN-ISOLDE CERN-MEDICIS facilities contains radioactive 139Ce16O also zinc or gold, depending on catcher foil used. A method using ion-exchange extraction chromatography resins in two column steps has been developed...
Terbium-155 has been identified for its potential single-photon emission computed tomography (SPECT) in nuclear medicine. For activity measurements, an accurate and precise half-life of this radionuclide is required. However, the currently evaluated 5.32(6) d with a relative standard uncertainty 1.1% determines precision possible. Limited literature measurements available all reported investigations are prior to 1970. Further therefore needed confirm accuracy improve use clinical setting....
Respirator filters marketed for protection against agricultural dusts have been tested their ability to retain actinomycete spores implicated in farmer's lung disease. Because mixed cultures gave variable estimates, media selective Thermoactinomyces spp., mostly T. vulgaris Tsiklinsky (spores 0.6–1.0 μm dia.) were used. penetrated all filter types: up 44% through nuisance dust filters, 3% cartridge British Standard BS2O91 Type A standard, 0.3% BS 2091 B standard cartridges, 0.1–3.1%...
Abstract In this work alternative methods for the production of terbium isotopes, and in particular 152 Tb 155 Tb, have been investigated. These which could be used theragnostics, produced using an alpha a proton beam incident on europium gadolinium targets, respectively. The experimental results compared with predicted cross-sections, calculated TALYS PACE4 code.
