• 2010:21 Childhood leukaemia around nuclear facilities

  The first indication of a possible relationship between living close to a nuclear installation and the risk of childhood leukaemia came from the United Kingdom in 1983. A cluster of childhood leukaemia ... clusters of leukaemia around nuclear installations are rare, only three well documented clusters, and three possible cases, have been found. The reason for the ob-served clusters remains unknown. In particular...

• 2010:12 An Evaluation of Models of Bentonite Pore Water Evolution

  result of reaction between groundwater and buffer minerals. The rather minor occurrences of the most rapidly reacting minerals in the buffer will have the most immediate and observable influences, but contributions ... solubility and sorption depend on the buffer chemical conditions. Moreover, pore-fluid composition at the interface between the buffer and the surrounding bedrock is important for the modelling and assessment...
