我们开party你来不？
After irradiation, readout of the TLD samples was done with a TLD reader and comparison of the glow curve under different proton energies was initiated. Results: The result showed that the TLD-200, TLD-300 sensitivities increased while proton energy decreased, which was consistent with track structure theory.

Another kind of imaging reagent of radioactive 3-quinuclidinyl 4-iodobenzilate was also studied in this paper. Iodine-123 was the ideal isotopes of radioiodine for SPECT (Single Photon Emission Computed Tomography) imaging and was elected to label peptides and other compounds, but for it is expensive and not easy to obtain in our lab, iodine-125 was substituted to study the labeling method and primary biodistribution.
碘-123以其合适的γ射线能量（159KeV，83％）而成为SPECT的理想选择，但由于碘-123主要通过加速器来制备，价格昂贵，不易得到，因此在方法学研究和初步的动物实验中，我们使用碘-125来代替碘-123，并建立起一套完整、可靠的方法，为碘-123标记奠定基础。
Thanks to the relatively high atomic number, high density and wide band-gap, CZT detector possesses sharp energy resolution and high detection efficiency without cryogenic cooling. A prototype planar CZT detector with sensitive volume of Φ 8mm×1.7mm has been fabricated and the gamma-ray spectra of 241Am were obtained. At room temperature (22℃) and for the 59.54keV peak, the FWHM can achieve 2.06keV, while no polarization is observed and stability is very satisfactory.

The relative detection efficiency of a lithium glass detector used as a neutron beam monitor in gamma-ray total absorption facility was simulated by Geant4. The neutron detection efficiency of the lithium glass detector was obtained between 10 keV and 1 MeV. Some factors affecting the efficiency were analyzed. The effect of the time delay caused by the elastic scattering upon TOF (time-of-flight) measurement, and the n-γ discrimination in different thickness lithium glass were discussed.
