Abstract
Of the total radiant flux produced in a right-circular cylindrical cell containing a uniformly distributed isotropic source of radiant energy, the fraction emanating from the end window is computed both for a cell with ideal, perfectly reflecting mirror surfaces and for a cell with ideal, totally absorbing surfaces. Graphs are presented of the calculated radiant-flux fractions from the cylinder as a function of the absorbance of the contents. Also presented are results of measurements of the radiant flux emitted from a cylindrical cell containing an externally excited scintillating solution when the inner reflecting surfaces of the cell are (1) polished aluminum, (2) aluminum evaporated on glass, (3) aluminum oxide, and (4) Teflon. These results are expressed relative to the radiant flux emitted by the same cell-solution combination with blackened inner cell surfaces. The actual radiant-flux fractions emitted by the cells are estimated by using the calculation for a cell possessing ideal, totally absorbing surfaces.
