A new determination of the 229Th half-life was made based on measurements of the 229Th massic activity of a high-purity solution for which the 229Th molality had previously been measured. The 229Th massic activity was measured by direct com...
Phase stability and lithium loading capacity in a liquid scintillation cocktail [0.03%]
液体闪烁实验液的相稳定性及锂载量研究

Liquid scintillation cocktails loaded with neutron capture agents such as 6Li are used in both neutron and neutrino detectors. For detectors designed to operate over extended timespans, long-term stability can be a concern. We demonstrate t...
The use of columns of the zeolite clinoptilolite in the remediation of aqueous nuclear waste streams [0.03%]
氯坡托石分子筛柱在处理核素废水中的应用研究

Alan Dyer et al.
Mud Hills clinoptilolite has been used in an effluent treatment plant (SIXEP) at the Sellafield nuclear reprocessing site. This material has been used to remove 134/137Cs and 90Sr successfully from effluents for 3 decades. Samples of the ze...
Plutonium and thorium isotopes in the bottom sediments of some Mazurian Lakes (Poland) [0.03%]
波兰梅斯尔湖底沉积物中的钚和钍同位素

J W Mietelski et al.
Presented are results on the Pu and Th isotopes activity concentration found in the upper part of bottom sediments collected from a deep part of 29 lakes in N-E Poland by diving in 2000. Analyses of Pu isotopic ratios allowed for the discus...
Study of fast and slow consecutive processes by heterogeneous isotope exchange using P-32 radiotracer [0.03%]
利用P-32放射示踪剂进行异核同位素交换研究快慢连续过程

The sorption of phosphate on soils is studied by radioisotopic tracer method. Two consecutive processes with rather different rates were differentiated: namely the heterogeneous isotope exchange between the phosphate in the soil solution an...
Time evolution of Fukushima-derived radiocesium in the western subtropical gyre of the North Pacific Ocean by 2017 [0.03%]
源自福岛的放射性铯在北太平洋西部副热带环流中的时间演变至2017年

Yuichiro Kumamoto et al.
In 2015-2017, we measured activity concentration of radiocesium in the western subtropical gyre of the North Pacific Ocean and revealed the time evolution of radiocesium derived from the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accide...

Nuclear energy has been a part of the energy mix in many countries for decades. Today in principle all power producing reactors use the same techniqe. Either PWR or BWR fuelled with oxide fuels. This choice of fuel is not self evident and t...
What you can see by developing real-time radioisotope imaging system for plants: from water to element and CO2 gas imaging [0.03%]
植物实时放射同位素成像系统的发展使我们能够看到什么：从水分到元素和二氧化碳气体的成像

Since plants live on inorganic elements, absorbing ions from roots and transferring them to each tissue in a plant is an essential activity. However, little is known about the movement of the elements or water in plant tissue. Though fluore...
Estimate of Fukushima-derived radiocaesium in the North Pacific Ocean in summer 2012 [0.03%]
2012年夏季福岛核事故铯放射性同位素释放量估算及对北太平洋的影响

Distributions of radiocaesium (134Cs and 137Cs) derived from the Tokyo Electric Power Company (TEPCO) Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident in the North Pacific Ocean in the summer of 2012 were investigated. We have estima...
Measurement of the 231Pa/235U ratio for the age determination of uranium materials [0.03%]
利用231Pa与235U的比值测定铀材料年龄
Zsolt Varga,Adrian Nicholl,Erich Hrnecek et al.
Zsolt Varga et al.
The paper describes the age (production date) determination of uranium reference materials using the 231Pa/235U ratio. Direct addition of 237Np in secular equilibrium with its 233Pa daughter was chosen instead of the regular milking of 237N...
