Abstract
The response of the 10–50 kGy range dichromate dosimeter (2.0 mM K 2Cr 2O 7, 0.5 mM Ag 2Cr 2O 7, 0.1 M HC1O 4) has been studied in pulsed electron beams with doses per pulse ranging from 30 to 600 Gy (1–4 μs pulses, 12.5pps). Relative monitoring of absorbed dose was achieved by placing a glass encapsulated thermistor within the dosimeter solution. No significant effect of dose rate could be observed within the precision of the experiment (±2%) over this range of dose rates. Results are also presented of computer simulations of dosimeter response based on the known reaction mechanism. These calculations confirm the absence of dose rate effects up to 600 Gy per pulse.
