Tracing U mobility in deep groundwater using Ra isotopes

The mobility of natural U is compared among four boreholes in a fractured granite using Ra isotopes and geochemical modelling. Rn-222/Ra-226 activity ratios (ARs) spanning an order of magnitude underline differences in reactive surface area. (Ra-224/Ra-228)(ARs) up to 9 indicate recent changes in hydrogeochemistry, and (Ra-226/Ra-228)(ARs) 0.6-30 indicate variable deposition of U. Dissolved U is related to dissolution of a solid U(VI) phase by groundwater with HCO3- > 20 mg.L-1. U reduction is hindered by Ca2UO2(CO3)(3)(0)

The Constitutionalisation of Contract Law in Finland

This chapter discusses the constitutionalisation of Contract law in Finland and makes frequent comparative references to the other Nordic systems. It aims to describe how Constitutional law has gradually started to influence Contract law. Moreover, the analysis seeks to predict some key future developments concerning Constitutional Contract law in Finland. This chapter illustrates how relevant constitutional actors consider these two areas of law and how these actors may sometimes collide because of key doctrines and the constitutional structure. It is concluded that references to Constitutional and Human rights law are not going to replace traditional Contract law argumentation. In most cases, nevertheless, Constitutional and Human rights law offer a useful means to clarify and modify the arguments used in traditional Contract law reasoning. The authors expect growing significance and legal relevance of the relationship between Constitutional law and Contract law.Peer reviewe
