Response of alanine dosimeters at very high dose rate

Alanine dosimeters were irradiated at 3 × 1010 Gy/s using a pulsed electron beam. The response measured by ESR showed good agreement with dosimetry by radiochromic film dosimeters, which are reliable at that absorbed dose rate. The results indicate that alanine dosimeters may be used at very high dose rate, within their nominal-usable dose range up to 100 kGy.
