Three other options are presently being studied, with an eye on including them in the forthcoming 3270 version. One of these is the equations of Helgeson, Kirkham, and Flowers (41). for which further model development is required. The second (42) is based on the hydration theory concept of Stokes and Robinson (43). This also requires further model development. The third set is a model (44) recommended by the European Nuclear Energy Agency for obtaining equilibrium constants for the formation of aqueous complexes of interest in nuclear waste disposal, such as of uranium and plutonium.

The mean radon concentrations determined by the passive detectors are based on calibrations using NBS standard radium-226 solutions and also from participation in the OECD (Nuclear Energy Agency)/CEC radon dosimeter intercomparisons (Commission of the European Communities, 1986) held at the U.K. National Radiological Protection Board (NRPB). Recent calibrations of the new LR-115 based detectors, in terms of response to radon concentrations and F factors have been carried out at the NRPB, which assistance is greatly appreciated. For the etching and track counting procedures used the inner LR-115 piece in the detectors has a mean sensitivity of approximately 1.6 tracks cm 2 kBq l m hr l.

In Japanese watersheds, Cs is mainly derived from the radioactive fallout of nuclear fission during weapon tests in the atmosphere (Wise, 1980). The majority of the tests were conducted during the period 1950-1962. The total injection of Cs to the atmosphere from these tests is estimated to be 960 PBq (lO Bq) (UNSCEAR, 1982). The Chernobyl accident in 1986 resulted in several times greater fallout of Cs in European countries compared to the weapon fallout (Nuclear Energy Agency, 1995). However, it increased only about 4% of the integrated deposition density of Cs in Japan at the time of accident (1986). 

The area of SMRs have been the subject of several major studies in recent years, principally carried out by international organizations such as the IAEA, European Union (EU) and Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (NEA/OECD). These activities can be summarized as follows ...
