QUALITY CONTROL AND DOSE REDUCTION IN GENERAL DIAGNOSTIC X-RAYS IN BANGKOK.
Keywords:
Radiation protection, entrance surface dose and effective dose.Abstract
The quality control of x-ray units has been installed in three university hospitals in Bangkok. Thermoluminescent dosemeters were used to measure the entrance surface dose of patients having general x-ray examination. New techniques are applied for dose reduction and the diagnostic quality of imaging is keeping. The effective doses were calculated by Monte Carlo techniques. Patient doses were very much lower than the permissible dose recommended by the International Commission of Radiation Protection in 1990.
