Calibration of a scintillation dosemeter for beta rays using an extrapolation ionization chamber

Med Phys. 2004 May;31(5):1123-7. doi: 10.1118/1.1709490.

Abstract

A scintillation dosemeter is calibrated for 90Sr/90Y beta rays from an ophthalmic applicator, using an extrapolation ionization chamber as a reference instrument. The calibration factor for the scintillation dosemeter agrees with that given by the manufacturer of the dosemeter within ca. 2%. The estimated overall uncertainty of the present calibration is ca. 6% (2 sd). A calibrated beta-ray ophthalmic applicator can be used as a reference source for further calibrations performed in the laboratory or in the hospital.
