Abstract

ISO/ASTM 51276:2002 covers procedures for using hermetically sealed polymethylmethacrylate (PMMA) dosimeters for measuring absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose in water. This practice covers systems that permit absorbed dose measurements under the following conditions:

absorbed dose range is 0,1 kGy to 100 kGy;

absorbed dose rate is 1 × 10^-2 to 1 × 10⁷ Gy·s^-1;

radiation energy range for photons is 0,1 MeV to 50 MeV, and for electrons 3 MeV to 50 MeV;.

irradiation temperature is - 78 °C to + 50 °C.
