A new approach to estimate nuclide ratios from measurements with activities close to background

Measurements of low-level radioactivity often give results of the order of the detection limit. For many applications, interest is not only in estimating activity concentrations of a single radioactive isotope, but focuses on multi-isotope analyses, which often enable inference on the source of the activity detected (e.g. from activity ratios). Obviously, such conclusions become questionable if the measurement merely gives a detection limit for a specific isotope. This is particularly relevant if the presence of an isotope, which shows a low signal only (e.g. due to a short half-life or a small transition probability), is crucial for gaining the information of interest.

松阳峰洞岩迪开石的矿物学研究

本文较详细地描述了产于浙江松阳峰洞岩迪开石矿床中的6个迪开石样品的矿物学特征;同时,发现部分样品中存在迪开石-高岭石无序混层,偏光显微镜下呈扇形蠕虫状,扫描电子显微镜下呈似香蕉状,波谱曲线上也有一定的显示,认为该混层是高岭石向迪开石转换过程中的中间产物。 峰洞岩迪开石的结晶度(HI)值与结构内全铁含量(x)间呈良好的负线性关系,线性回归方程为HI=1.811-5.787X,相关系数r=-0.9731,表明迪开石的结晶程度明显受控于其结构内类质同象置换的全铁含量。峰洞岩迪开石系热液蚀变而成,形成温度在110～140℃之间,不超过160℃。     

Structure relationship for catalytic dechlorination rate of dichlorobenzenes in water

Three isomers of dichlorobenzene (o-, m- and p-DCB) were dechlorinated by Pd/Fe catalyst in aqueous solutions through catalytic reduction. The dechlorination reaction took place on the surface site of the catalyst via a pseudo-first-order kinetics, and resulted in benzene as the final reduction product. The rate constants of the reductive dechlorination for the three dichlorobenzenes (DCBs) in the presence of Pd/Fe as a catalyst were measured experimentally. In all cases, the reaction rate constants were found to increase with the decrease in the Gibbs free energy of the formation of DCBs. The reaction rate constant for o-, m- and p-DCBs in the presence of 0.020% (w/w) Pd/Fe at 25 °C was determined to be 0.0213, 0.0223, and 0.0254 min⁻¹, respectively. While the activation energy of each dechlorination reaction was measured to be 102.5, 96.6 and 80.0 kJ mol⁻¹ for o-, m- and p-DCBs, respectively. The results demonstrated that p-DCBs were reduced more easily than o- or m-DCBs, and the order of the tendency of the dechlorination was p-DCB > m-DCB > o-DCB. The presented data show the catalytic reduction using Pd/Fe as a catalyst is a fast and easy approach for the dechlorination of DCBs.
