ISO 51650 covers the preparation, handling, testing and procedures for the use of cellulose acetate dosimetry systems, and the spectrometric, densitometric or photometric read-out equipment for measuring absorbed doses in materials irradiated by photons and electrons in terms of absorbed dose in water.
Cellulose acetate dosimeter refers to untinted and tinted cellulose triacetate (CTA) or cellulose diacetate (CDA) film dosimeter.
This practice applies to cellulose acetate film dosimeters that can be used within part or all of the specified ranges as follows:
the absorbed dose range for untinted CTA is 5 times 103 Gy to 3 times 10 5 Gy for photons and electrons;
the absorbed dose range for tinted CDA is 1 times 104 Gy to 1 times 10 6 Gy for photons and electrons;
the absorbed dose rate for both CTAand CDA is from 0,03 to 4 times 1010 Gy s -1;
the radiation energy range for photons is from 0,1 MeV to 50 MeV;
the radiation energy range for electrons is from 0,2 MeV to 50 MeV;
the irradiation temperature range is from - 10 °C to 70 °C.
