【 摘 要 】

Measurement traceability of dosimetry systems to standards of measurement underpins reliable radiation treatments. A method to determine the product of the molar linear absorption coefficient and the radiation chemical yield is presented, which provides a means of photometric calibration of chemical dosimetry systems in order that the absorbed dose be determined directly from photometric measurements.
