For the purpose of investigation of the total dose effect of natural radiation and cosmic rays on electronic devices, we carried out observations of radiation counts in them for elapsed time at two different height locations ; Chofu (30m) and Sugadaira (1300m) in Japan. Using a MCA (Multichannel Analyzer) with NaI detector, radiation counts were accumulated for times from 1 to a maximum of 168 hours. At Sugadaira location 15 % more counts were recorded than at Chofu. Accelerated exposure experiments for LSI were carried out by γ-ray source irradiation to estimate the soft error rate. The We attempted to measure natural and cosmic radiations using the detector probe attached with scintillating fluorite crystals : KMgF_3 : Ce, CaF_2 : Eu and CaF_2 : Eu, Gd grown in the laboratory, and the performances of crystals as scintillators were evaluated by fluorescence, excitation spectra and γ-ray radiation experiments. For CaF_2 : Eu crystal, we abtained the intense emission of 2.5×10^4photons/cm^3, although the energy resolusion was 605keV for the half-width.

为了研究天然辐射和宇宙射线对电子器件的总剂量效应，我们在日本的长府(30m)和杉原(1300m)两个不同的高度对电子器件进行了辐射计数的观测。使用带有NaI探测器的MCA(多通道分析仪)，累积辐射计数的次数从1到最大168小时。在Sugadaira地点，记录到的计数比在Chofu多15%。利用γ射线源辐照对大规模集成电路进行了加速曝光实验，以估计软错误率。我们尝试用实验室生长的闪烁萤石晶体KMgF_3：Ce，CaF_2：Eu和CaF_2：Eu，Gd的探测器探针测量自然辐射和宇宙辐射，并通过荧光、激发光谱和γ-射线辐射实验评价了晶体的闪烁性能。对于CaF_2：Eu晶体，我们获得了2.5×10~(-4)光子/厘米~3的强发射，尽管能量分辨率为605keV。
