✦ Synopsis
Alanine and radiochromic film dosimeters were irradiated with absorbed doses from 3 to 10 kGy at a I0 MeV electron accelerator under typical radiation processing conditions. The nominal doses were measured by graphite calorimeters and the dosimeters were irradiated in graphite phantoms. The dosimeters were calibrated by irradiation with 6°Co photons.
The ratios of calorimeter to film and alanine dosimeter readings were generally within 0.99 + 0.01 for 10 mm phantoms, but larger differences were observed for 20 mm phantoms. The discrepancies may be due to uncertainties in irradiation geometry, or in the stopping power ratios applied.
