[en] It appears that 90Sr can be used as a measure of the fission produce contamination of water. A very sensitive method of water analysis of 90Sr to 90Y using ion exchange concentration with selective elution of 90Y is described. Low-level techniques are employed to count the 90Y which reflects the concentration of 90Sr. Twenty-six liters of city tap water were concentrated and found to contain 3.10 + 0.21 x 10-4 dpm/m1 of 90Sr. If interferring activities are present, the 90Sr can be eluted, and radiochemical separation performed

[en] Over the next 40 years, the combustion of fossil fuels for generation of electricity and vehicle transportation will be significantly reduced. In addition to the business-as-usual growth in electric energy demand for the growing world population, new electricity-intensive industries, such as battery electric vehicles and hydrogen fuel-cell vehicles will result in further growth in world consumption of electric energy. Planning for a sustainable supply of electric energy in the diverse economies of the world should be carried out with appropriate technology for selecting the appropriate large-scale energy resources based on their specific energy. Analysis of appropriate technology for the available large-scale energy resources with diminished use of fossil fuel combustion shows that sustainable electricity supply can be achieved with equal contributions of renewable energy resources for large numbers of small-scale distributed applications and nuclear energy resources for the smaller number of large-scale centralised applications.
