ISO/ASTM 51275 covers the handling, testing and procedure for using a radiochromic film dosimetry system to measure absorbed doses in materials irradiated by photons or electrons in terms of absorbed dose in water. This practice applies to radiochromic film dosimeters that can be used within part or all of the specified ranges as follows:
absorbed dose range 1 Gy to 100 kGy;
absorbed dose rate 1 times 10-2 Gy/s to 1 times 10 13 Gy/s;
radiation energy range for both photons and electrons 0,1 MeV to 50 MeV;
irradiation temperature range - 78 to + 60°C.
ISO/ASTM 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 placement of any of these formats.
