适用范围：This practice covers the preparation, handling, testing and procedures for the use of cellulose acetate dosimetry systems, and the spectromctric, densitometric, or photo-metric readout equipment for measuring absorbed dose in materials irradiated by photons and electrons in terms of absorbed dose in water. Note 1—Cellulose acetate dosimeter refers to untinted and tinted cellulose triacetate (CTA) or cellulose diacetate (CDA) film dosimeter.This practice applies to cellulose acetate film dosime-ters that can be used within part or all of the specified ranges as follows:The absorbed dose range for untinted CTA and CDA is 5 × 10 to 3 × 10 Gy for photons and electrons,The absorbed dose range for tinted CTA and CDA is 1 × 10 to 1 × 10 Gy for photons and electrons,The absorbed dose rate for both CTA and CDA is from 0.03 to 3 × 10 Gy/s,The radiation energy range for photons is from 0.1 to 50 MeV, and The radiation energy range for electrons is from 0.2 to 50 MeV. Note 2—In cases where low-energy electrons and charged particles cannot completely penetrate the thickness of standard CTA and CDA films, thin films may be used (1,2).The irradiation temperature range is from -10 to 70℃.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 appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.
