ASTM E2304

1.1 This practice covers the handling, testing, and procedure for using a lithium fluoride (LiF)-based photo-fluorescent film dosimetry system to measure absorbed dose (relative to water) in materials irradiated by photons or electrons. Other alkali halides that may also exhibit photofluorescence (for example, NaCl, NaF, and KCl) are not covered in this practice. Although various alkali halides have been used for dosimetry for years utilizing thermoluminescence, the use of photoluminescence is relatively new.

1.2 This practice applies to photo-fluorescent film dosimeters (referred hereafter as photo-fluorescent dosimeters) that can be used within part or all of the following ranges:

1.2.1 Absorbed dose range of 5 10^-2 to 3 10² kGy (1-3).

1.2.2 Absorbed dose rate range of 0.3 to 2 10 ⁴ Gy/s (2-5)).

1.2.3 Radiation energy range for photons of 0.05 to 10 MeV (2).

1.2.4 Radiation energy range for electrons of 0.1 to 10 MeV (2).

1.2.5 Radiation temperature range of -20 to +60°C (6,7).

1.3 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.
