[en] The published information on environmental measurements and on discharges to sea and atmosphere from the Sellafield site has been used to enable estimates to be made of present and past radiation doses to members of the public in West Cumbria. Most of the available data relates to the groups of individuals in the population who are most highly exposed by virtue of their habits or their locations (the critical groups) and whose exposure has therefore been closely monitored. The doses to these groups have been estimated, but, in addition, consideration has been given to the exposure of average members of the public living in west Cumbria. Exposures as a result of external irradiation, and due to intakes of radionuclides by inhalation and ingestion have been evaluated. As a means of providing perspective, doses are compared with those arising naturally due to background radiation. (author)

[en] Values are reported for the enthalpy of solution of ScCl₃, YCl₃, LaCl₃, GdCl₃, YbCl₃, YBr₃, LaBr₃, YbBr₃, ScI₃, YI₃, LaI₃, and GdI₃ in water, of ScCl₃, YCl₃, LaCl₃, GdCl₃, YbCl₃, ScI₃, YI₃, LaI₃ and GdI₃ in methanol and in dimethyl sulphoxide, of LaCl₃ in ethylene glycol, of GdCl₃ in dimethylformamide, and of LaI₃ in dimethylformamide, propylene carbonate, and ethanol. These values are related to earlier published values in similar systems, and are considered in relation to solvating properties for the cations and halide ions. (author)

[en] Solubilities of Cs₂[ReCl₆] in methanol-, ethanol-, and t-butyl alcohol-water mixtures, and of Cs₂[ReBr₆] and Cs[ReO₄] in methanol-water mixtures, are reported. Correlation of these solubilities with various solvent and solubility parameters is discussed; a simple correlation of solubilities with solvent composition and cosolvent characteristic volume is remarkably satisfactory.

[en] Enthalpies of solution of the following are reported: GaCl₃ and GaI₃ in water, methanol, and dimethyl sulphoxide; InCl₃ and InI₃ in water and in several non-aqueous solvents; ThCl₄, ThI₄, and UCl₄ in methanol, ethanol, and dimethyl sulphoxide. (author)

[en] Nuclear industry advertising in the United Kingdom is becoming more and more frequent, and is often controversial. The content and impact of recent campaigns are considered, especially the advertisement which portrays nuclear power as beneficial to the greenhouse effect. (author)

[en] The enthalpy of hydrolysis of ReF₇(c) in Na[0H](1 mol dm^-3 at 298.2 K) is -972 +- 11 kJ mol^-1. From this result the enthalpy of formation of ReF₇(c) is estimated to be -1 432 +- 11 kJ mol^-1. (author)

[en] Procedures are described for calculating internal pressures of water and deuterium oxide at given temperatures and pressures. The dependences on pressure of temperatures of maximum density are described using quadratic equations. Similar equations describe the dependences on pressure of the temperature at which internal pressures are zero. Equilibrium and configurational internal pressures are identified, the latter being linked to reorganisation of hydrogen bonds in water and in deuterium oxide. (author)
