1.1 This practice covers the handling, testing, and procedurefor using a radiochromic film dosimetry system to measure absorbeddose in materials irradiated by photons or electrons in terms ofabsorbed dose in water.

1.2 This practice applies to radiochromic film dosimeters thatcan be used within part or all of the specified ranges asfollows:

1.2.1 The absorbed dose range is 1 Gy to 100 kGy.

1.2.2 The absorbed dose rate is 1 10-2 to 11013 Gy/s (1-4).

1.2.3 The radiation energy range for both photons and electronsis 0.1 to 50 MeV.

1.2.4 The irradiation temperature range is -78 to +60°C.

1.3 This practice applies to radiochromic films of variousformats, including small pieces used to measure a single dosevalue, strips used for one-dimensional dose-mapping, and sheetsused for two-dimensional dose-mapping. Three-dimensionaldose-mapping may be achieved by proper placement of any of theseformats.

1.4 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establishappropriate safety and health practices and determine theapplicability of regulatory limitations prior to use.
