Earlier detection technology in doses below 1Gy, there is a sample displacement, the fluorescence intensity is too weak to detect problems on the cause misalignment. The optical properties of the sample analysis, and countermeasures to improve the establishment, in the case where the sample 1Gy, we improved optical design, analysis of samples for the same lifetime curve emitting ultraviolet make an effective measurement technique. The S/N ratio for 1Gy sample is above 4. On the other hand, at low doses detection technology, we use a photomultiplier tube measuring fluorescence lifetime of different samples, and adjust the gain control voltage measurements made at low dose measurements have a new breakthrough. We have done mid dose and 0Gy sample test, lifetime decay with time can be detected.
