Calculations of Eu and ‘“Eu activities in the Chcmoby I Unit IV reactor are given, together with a discussion of the uncertainties involved and comparison with results of other authors. The measurement of activities of the Chernobyl-origin ‘fuel-like’ hot particles (fuel fragments) and analysis of the radionuclide fractionation reveal a common behaviour of L”Eu ’ Eu and “‘Ce radioisotopes as regards non-volatility, similar to rsZr and ‘%lb in hot particles.

Discusses laboratory studies of the chemical reactions that could occur between fly ash and the flue gases in refuse incineration. Using fIy ash collected from an incinerator and subjecting this to simulated flue gases at different temperatures it is shown that the absorption of chlorine proceeds initially at a faster rate than fly ash absorption of SO,. $llO5T~l

Andrea Smith, IRA Greenhouse Gas Programme, CRE Group Ltd, Stoke Orchard Cheltenham, Glos. GL52 4RZ, UK f13.00. The report focuses on four major aspects, namely the manufacture of
chemicals and pol mers and enhanced oil recovery, as well as two biological methods to re Buce or fur carbon dioxide emissions (direct and indirect fixation). Describes each approach in detail and includes data from studies worth f 180,000, commissroned specifically for the Programme. 95105256 Carbon taxatlon and unexpected swltchlng behavlaur Brennand, G. J. OPEC Review, Spring 1995, 19, (l), 1-12. The bulk of the carbon-saving generally exnected to brought about by a carbon tax is due to increased%icentives to conserve energfl. By focusing upon carbon content, it is intended that the necessary economic si nals will induce additionally a switch away from high carbon content fue Ps to ones with a lower carbon content. This note proposes that there may be examles where this switch may not necessanly occur, and that there may even & cases where the switch will be in the wrong direction.

The or anic carbon content of the soil increased with increasing pollution load. %hermal power plant emissions have led to significant increases in the soil sulphate sul hur and exchangeable calcium contents, while reducin significantly totaP nitrogen. Reduction in total-N was possibly correlate % with the N-mineralization rate. The changes in total and organic sulphur. exchangeable potassium, and available phosphorus contents of sod were not significant. 95105259 Characterlsatlon and slgnal reconstructlon of an NDIR automotlve emlsslons analyser used for dynamic measurement Chart, S. H. and Cben. X. S. J. Institute of Energy,Jun. 1995, (475), 49-56. Normally the slow-response conventional gaseous-emission analysers based on non-dispersive infra-red measuring techniques are not widely used for measurement of transient engine-exhaust emissions! because the dynamics of these analysers distort emission signals dunng sampling processes. A phenomenological modelling approach is proposed which simulates the behaviour of gas transport through an emission analyser by a series of alternately arranged pipes and surge chambers, such that the distortion of the emission signal can be physrcall explamed and modelled. The characterisation of an emission analyser gy means of two physical modes-viz diffusion and perfect gas-mixing models-is adopted as the basis for analysis, so that physrcrd interpretation can be made to account for the resulting distortion and variation of measured emission signals. 95105259 Characterlzatlon of uranlum contamlnatlon In surface solls Schilk, A. J. et aL, J. Environ. Radioactivity, 1995, 26, (2) 147-156. Traditional means of obtaining radionuclide concentrations in soils over large areas are often time-consuming, cumbersome, expensive, and potentially non-representative. In an attempt to develop improved systems and new methodologies for the rapid and economical characterization of largescale uranium contamination, two disparate monitoring technologies were compared at a contaminated site within the Femald facility near Cincinnati, Ohio, USA.
