Abstract:
The structural principles and technical performances of different ionization chamber dosimeters used in radiotherapy have been briefly introduced in this paper. In the mean time, a comparison of technical performances of four different kinds of ionization chamber dosimeter used in hospitals in China has also been made. The data show their quality meet the required specification specified by IEC731 and JJG912-96, so they can be used as field survey dosimeters in hospitals. Some precautions in using these dosimeters are given here too.
