Scope

This standard specifies the preparation of ferrous sulfate dosimeter (Fricke dosimeter) and the method of using ferrous sulfate dosimeter to measure the absorbed dose of ionizing radiation in water. This standard applies to the measurement of absorbed dose in water of medical radiation therapy level (limited beam) and radiation processing level (unlimited beam), and its scope of application is: absorbed dose: 40 ~ 400Gy; absorbed dose rate: less than 10 Gys^-1; Radiation energy: 0.1~30MeV for photons, 1~30MeV for electron beams; Irradiation temperature: 10~60℃, 20~25℃ during calibration (see Appendix D). This standard also applies to the calibration and verification of transfer dosimeters and conventional dosimeters.
