ASTM E1276-96e1

1.1 This practice 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.

1.2 This practice covers systems that permit absorbed dose measurements under the following conditions:

1.2.1 The absorbed dose range is 0.1 to 50 kGy.

1.2.2 The absorbed dose rate is 1 X 10-2 to 1 X 107 Gy[dot]s-1.

1.2.3 The radiation energy range for photons is 0.1 to 50 MeV, and for electrons 3 to 50 MeV.

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

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
