1. Scope
1.1 This practice covers the procedures for preparation, handling, testing, and using radiochromic liquid dosimetry systems of radiochromic dye solutions held in sealed or capped containers (for example, ampoules, vials). It also covers the use of spectrophotometric or photometric readout equipment for measuring absorbed dose in materials irradiated by photons and electrons.
1.2 This practice applies to radiochromic liquid dosimeter solutions that can be used within part or all of the specified ranges as follows:
1.2.1 The absorbed dose range is from 0.5 to 40 000 Gy for photons and electrons.
1.2.2 The absorbed dose rate is from 103 to 1011 Gy/s.
1.2.3 The radiation energy range for photons is from 0.01 to 20 MeV.
1.2.4 The radiation energy range for electrons is from 0.01 to 20 MeV.
Note 1—Since electrons with energies less than 0.01 MeV may not penetrate the container of the solution, the solutions may be stirred in an open beaker with the electrons entering the solutions directly (1).
1.2.5 The irradiation temperature range is from -40 to +60°C.
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.
