Sažetak
The main purpose of the IAEA/WHO TLD postal audit programme for dosimetry in radiotherapy is to provide independent verification of the dose delivered by treatment machines in radiotherapy centres. The results of the TLD audit are considered acceptable if the relative deviation between participant's stated dose and the TLD determined dose is within ± ; 5%. The IAEA maintains a strict internal quality control of the TLD system. The system calibration is verified at every reading session and the dose response and fading are verified regularly. There are 7 hospitals (with all together 6 60Co sources and 7 accelerators) in which radiotherapy in Croatia is performed. In 2003 and 2005 TLD audit was organized for all radiotherapy centres ; it included 6 60Co sources and 12 high-energy X-ray beams. The maximum deviation between participants' and IAEA determined doses were 5% and 4% in 2003 and 2005 respectively. The method of dose comparison and the results will be discussed in the paper in details.
