According to recent research from the United States, "Over the course of the last decade, routine monitoring of the alanine dosimetry system revealed a small but significant observation that, after examination, led to the characterization of a previously unknown absorbed-dose-dependent, dose-rate effect for the alanine system. The newly discovered rate effect is of potential concern for electron-beam dosimetry, since electron-beam dosimetry typically derives its traceability to national standards through comparisons to gamma-ray calibrations of the dosimetry system."
"The largest discrepancy in source dose rates is between gamma-ray sources and electron-beam ...
