1. Scope
1.1 This practice covers procedures for using the cellulose triacetate (CTA) dosimetry system for measuring absorbed dose and dose profile in materials irradiated by electrons and photons in terms of absorbed dose to water. The CTA dosimeter is a routine dosimeter especially useful for measurement of dose distribution.
Note 1
Cellulose triacetate dosimeter refers to untinted film dosimeter.
1.2 This practice applies provided the following conditions are satisfied.
1.2.1 The absorbed-dose range is 10 kGy to 300 kGy for electrons and photons.
1.2.2 The absorbed-dose rate range is 3 Gy/s to 410 10 Gy/s ().
1.2.3 The radiation-energy range for electrons is 0.2 to 50 MeV.
1.2.4 The radiation-energy range for photons is 0.1 to 50 MeV.
1.2.5 The irradiation-temperature range of the dosimeter is -10 to 70C.
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.
