According to the energy specialty of β-particle of Pm,the three most important things to be done for improving the detective efficiency are: to choose a low-noise photoelectrical multiple-canal; to develop the flickering three-united-benzene crystal; and to design the appropriate electrical circuits.

Monte Carlo simulation of photon transport in a scintillation crystal array;

Comparison of properties of PET scintillation crystals;

X-ray excited fluorescence spectrometer and optical characteristics of scintillation crystals;

Comparative study of NaI,BGO,LSO,GSO and YSO scintillators using Monte Carlo simulations;

In this paper,the growth of inorganic scintillator Ce 3+:YAG with large size and high optical quality have been researched and its absorption and fluorescence spectra have also been measured and analyzed.

Lead tungstate(PbWO_4)is becoming one of the most promising scintillators due to its favorable scintillation properties such as high density,short radiation length,high radiation hardness and fast decay time.

Analysis on function of scintillation crystals in PET;

The Yb3+-doped scintillation crystals are novel kinds of scintillators, which may be applied to the detection of the solar neutrinos.

The research progress of the scintillators of new generation-the rare-earth scintillation crystals is reviewed.

Scintillators are materials which can be used to detect highly ionizing radiation, because they efficiently convert the energy of this radiation into light.
