1 This practice covers the procedures for handling, test-ing, and using a radiochromic film dosimetry system to measure absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose in water. 2 This practice applies to radiochromic film dosimeters that can be used within part or all of the specified ranges as follows: 2.1 The absorbed dose range is 1 Gy to 100 kGy. 2.2 The absorbed dose rate is 1 × 10 to 1 × 10 Gy/s (1-4). 2.3 The radiation energy range for both photons and electrons is 0.1 to 50 MeV. 2.4 The irradiation temperature range is -78 to +60℃. 3 This practice applies to radiochromic films of various formats, including small pieces used to measure a single dose value, strips used for one-dimensional dose-mapping, and sheets used for two-dimensional dose-mapping. Three-dimensional dose-mapping may be achieved by proper place-ment of any of these formats. 4 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. note: 2 The boldface numbers in parentheses refer to the bibliography at the end of this practice.
