Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I'd like to know if there is a maximum matrix size after which radiation counting (using a scintillator/photomultiplier) on a flat paper sample doesn't improve or is not significant.

Specifically this would refer to radiochromatograms, or chromatography strips of radioactive samples.

If the counting time is always the same, is there any difference in counting using a 64x64 or 256x256 matrix?

Reference papers (even titles only) would also be appreciated.

Thank you

Allison
