Efficient formation of inert Bi-213 chelates by tetraphosphorus acid analogues of DOTA: towards improved alpha-therapeutics
Published 2018-08-01“…Abstract Background The recently growing interest in targeted alpha-therapy (TAT) calls for improvement of the labelling chemistry of the corresponding radionuclides. 213BiIII is a short-lived alpha emitter which emits only one alpha particle in its decay chain. Hence, it might be safer in application than other respective nuclides, such as 223Ra or 225Ac, because no alpha-emitting daughters are released upon recoil. …”

The efficiency of gas-filled surge arresters in the environment contaminated by non-ionizing radiation of fusion reactors
Published 2022-01-01“…For the efficiency of the flexible model, it was found to be slightly less than 40% (and to be achieved by the application of alpha particle radiation). Since neither of these efficiencies guarantee reliable operation of the gas-filled surge arrester, it was concluded that essential electronics in the vicinity of the fusion generator must be protected. …”

Spatial structure of the plasma sheet boundary layer at distances greater than 180 R<sub>E</sub> as derived from energetic particle measurements on GEOTAIL
Published 1997-10-01“…Second, if we consider the same energy level of energetic particles, then the H<sup>+</sup> layer is confined within that of the energetic electron, the He<sup>++</sup> layer is confined within that of the proton, and the oxygen layer is confined within the alpha particle layer. Third, whenever the energetic electrons show higher fluxes inside the plasma sheet as compared to those at the boundary layer, their angular distribution is isotropic irrespective of the Earthward or tailward character of fluxes, suggesting a closed field line topology.…”
