We developed a high performance reference feeble light source composed of a scintillator and a gamma-ray source. This light source is useful to precisely measure the stability of feeble light measurement instruments, because the amount of luminescence from the scintillator depends only on the half-life of the gamma-ray source under the same configuration. A BGO crystal with the large efficiency for gamma rays was used as a scintillator. The feeble light was measured with an integrating sphere 6 inch in diameter, a photomultiplier tube, a photo diode and a spectrometer with a light guide of a plastic fiber. In this system, the amount of luminescence from the BGO scintillator was precisely measured, which led to successful calibration of conventional devices such as luminometers.

我们开发了一种由闪烁体和伽马射线源组成的高性能参考微弱光源。该光源对于精确测量微弱光测量仪器的稳定性很有用，因为闪烁体的发光量仅取决于相同配置下伽马射线源的半衰期。使用对伽马射线具有高效率的 BGO 晶体作为闪烁体。使用直径6英寸的积分球、光电倍增管、光电二极管和带有塑料纤维光导的光谱仪来测量微弱的光。在该系统中，精确测量了 BGO 闪烁体的发光量，从而成功校准了发光计等传统设备。
