Abstract :
The authors investigated many factors which affect the performance of ionization chambers. They carried out performance tests. Their aim is to assist users in maintaining their chambers and in making accurate dosimetric measurements. The following devices were checked: a 0.9 mCi Strontium-90 check device; a Clinac 600C (Varian); rigid stem and cylindrical chambers; an IO-4 electrometer
