Methods for Testing Micro-Dose X-Ray Radiation

Abstract:

The X-ray security inspection systems are widely used in airports, customs, and railway stations now. Their radiation safety is related to the health of public. It is necessary to take radiation safety tests at least once a year. For their energy is usually in the level of keV, the radiation caused by photoelectric effect is the most important. According to the photoelectric effect of X-ray, the methods of testing Micro-dose X-ray radiation include radiography method, ionization testing method, scintillation testing method and semiconductor testing method. Radiography method and ionization testing method can be used to test the stronger X-ray radiation, while scintillation testing method and semiconductor testing method can be used to test the weaker. Geiger counter testing method is not proper to be used when taking the accurate test; however, because of its relative low cost, non-professional technicians can use it to test the Micro-dose X-ray radiation daily.
