Fluo Yield

With this page you can calculate the fluorescence yield from a sample. Please fill-in the following form:

X-ray Beam intensity ph/s

Absorber density at/cm2

Absorber Z (>20)


Detector active surface cm2

Sample-detector distance cm

Expected rate=


Data for the atomic cross sections taken from W.H. McMaster, N. Kerr del Grande, J.H. Mallett, J. H. Hubbel LLNLR UCRL-50174 1969 whereas the fluorescence yield data are from M. O. Krause, J. Phys. Chem. Ref. Data 8 (1979), 307 .
