Abstract The desirable characteristics of dosimeters used in radiotherapy were reviewed, including ionization chamber, film, luminescence, semiconductor, plastic scintillator, diamond,and polymer gel dosimeters.The accuracy and precision, linearity, dose rate dependence, energy response, directional dependence and spatial resolution of the radiation dosimeters were compared.And the advantage and disadvantage of the characteristics of the different dosimeters were further described.
