WebApr 10, 2024 · Abstract. The isotope 210 Po is the main product of neutron activation in fast reactors cooled by molten lead-bismuth eutectic (LBE). The isotope 210 Po is a pure alpha emitter with a half-life of 138.38 days. For typical values of the neutron flux the 210 Po concentration in the coolant can reach 1–10 Ci/kg. While exposure of plant personnel to … WebBismuth sodium titanate (BNT) piezoelectric ceramic coatings with dense morphology and single perovskite phase were fabricated by thermal spray process.
