Active laser frequency stabilization using neutral praseodymium (Pr)
, 2009 We present a new possibility for the active frequency stabilization of a laser using transitions in neutral praseodymium. Because of its five outer electrons, this element shows a high density of energy levels leading to an extremely line-rich excitation

Validation of a New Design of Tellurium Dioxide-Irradiated Target
Nuclear Engineering and Technology, 2016 Production of iodine-131 by neutron activation of tellurium in tellurium dioxide (TeO2) material requires a target that meets the safety requirements. In a radiopharmaceutical production unit, a new lid for a can was designed, which permits tight sealing

Hair radioactivity as a measure of exposure to radioisotopes [PDF]
, 1972 Since many radioisotopes accumulate in hair, this tropism was investigated by comparing the radioactivity of shaved with plucked hair collected from rats at various time intervals up to 24 hrs after intravenous injection of the ecologically important ...
