Radiochemical Syntheses&colon; Radiopharmaceuticals for Positron Emission Tomography, Volume 1 (Editor, 2012)<br>4. The chemical and radiochemical purity is high. The first investigative radiochemical measurements began in the early days of nuclear fission. This process is used in radiochemical neutrino detectors. Boris Kidridzha heavy water reactor (capacity up to 10 MW), radiochemical, and various other laboratories. The radiochemical analysis method was pioneered by Herbert L. Anderson. The Radiochemical Laboratory had operated intermittently. In principle there are two ways of detecting solar neutrinos&colon; radiochemical and real time experiments. Activity coefficients can be determined by radiochemical methods. Fl has been considered of interest for future radiochemical studies. It is convenient given the very low event rates in radiochemical experiments.
