用成象板对纯钒进行了氢分布的定量测定。已经证明，氢在钒中的分布可以图形化地显示，并且已经评估了钒的晶粒表面上的氢浓度。使用这种方法，氚放射性发光，氢浓度已被发现不同的粮食。在目前的装料条件下，较高和较低氚浓度下的氚浓度分别为2质量ppb和0.7质量ppb;这些值分别对应于450质量ppm和160质量ppm的氚浓度。对于成像板中记录的光激励发光（PSL）强度，大部分强度归因于β射线，即，样品中氚产生的X射线成分仅为2%。
An imaging plate has been applied to pure vanadium to examine the hydrogen distribution, quantitatively. It has been demonstrated that the hydrogen distribution in vanadium can be graphically displayed, and the hydrogen concentration on a grain surface of vanadium has been evaluated. Using this method, tritium radioluminography, hydrogen concentration has been found to vary from grain to grain. The tritium concentrations at the higher and lower tritium concentration are 2 mass ppb and 0.7 mass ppb, under the present charging condition; these values correspond to the protium concentration of 450 mass ppm and 160 mass ppm, respectively. For the photo-stimulated luminescence (PSL) intensity recorded in the imaging plate, most of the intensity is attributed to the β-rays, i.e., the components of the X-rays generated from tritium in the specimen is only 2%.
