In vitro measurement of external pancreatic insufficiency - on duodenojejunal juice, by incubation with intrinsic factor and r-protein coupled to radioactivity vitamin=B12, then ppte. with antiserumIn vitro measurement of external pancreatic insufficiency is effected on a sample of duodeno-jejunal ...
The method is based on the principle of enclosing the source to be tested in a hermetically sealed container and measuring the radon radioactivity growth in the container as a function of time. A cylindrical modified Lucas cell, designed and built in our laboratory, is used for measuring the ...
The 20 kilo tonne (kton) liquid scintillator will be stored in a 0.6 kton acrylic sphere with 35.4 m diameter due to the good light transparency, chemical compatibility and low radioactivity of acrylic. The concentration of U/Th in acrylic is required to be less than 1 ppt (10 g/g) ...
