Mn$sup 56$ COINCIDENCE COUNTING FACILITY

Reactor Oscillator Determination of Capture-To-Fission Ratio in an Undermoderated Critical Assembly

“…The five foils from each of the irradiated samples were then counted in the beta-gamma coincidence arrangement used in connection with the manganese bath procedure for source calibration. 13 This yielded an absolute disintegration rate for the foils. Table XIII indicates the axial variation of flux within the turret as determined from the gamma counting of the background foils.…”

Detérmination of 85Kr in Aqueous Solution by Cerenkov Čounting in Water and Polyethylene

“…For water, η = 1.33, ßmin = 0.75, and the corresponding lower energy limit for beta particles is 0.26 MeV. Studies of Cerenkov counting for radioassay of aqueous samples have been reported by HABERER [3] and others [4][5][6][7][8][9][10][11][12]. In general, the principal advantage of Cerenkov counting, as pointed out by HABERER [3], is that essentially no preparation is required for aqueous samples.…”
