The average block costs for the year at the average consumption rates per head are as follows: Wet season $19.04 7 months Dry season $7.53 4 months Total $36.57 11 months Based on prices per tonne of: Phosrite $961.00 Uramol $925.00 The HighP block has apparently been reformulated for better Wet season stability. It will be tested together with Pro90 in 2001/02. PROJECT: Soil to Plant Uptake of Radioactivity Project Officers: P. Shotton (DPIF), J. Twining (ANSTO*) and P. Hausler (DPIF) Location: Douglas Daly Research Farm Objective: The aim of the trial is to determine the amount of radioactivity that may be taken up by cultivated plants used for animal and human consumption. Background: Nuclear power will have a role in the rapid industrial development occurring in the tropics, particularly given the need to reduce global greenhouse gas emissions and the increasing need for electricity. Hence, accurate and precise predictive models of radiological dose in tropical and sub-tropical regions of the planet are required should there be any atmospheric release of radioactive material. From ANSTO's perspective this is particularly relevant for the northern areas of Australia and across South East Asia. The data from this study will contribute significantly to the current low-level of knowledge that we have of the behaviour of these materials in tropical regions, particularly as the soil types being used are representative of large areas of agricultural regions within the tropics. The overall aim is to provide better emergency response planning but the study will also contribute to our understanding of general elemental biokinetics in crops. Method: The trial is located on two soil types (Tippera and Blain) at DDRF. The location was selected and the site was prepared in 1999. Fences and enclosures were completed in October 1999 and the areas pre-watered and the first treatments applied on 15/10/99.The area consists of: Actual treated areas 30m2 Enclosed area 110m2 Quarantine areas 2,500m2 Each year, sorghum and mungbeans are planted at each site with each crop alternating locations yearly. All areas were applied with recommended fertilisers, planting rates, weed control herbicides and insecticides when required. Water was applied to the areas to assist with establishment. Strontium (85 Sr) is applied to both sites each year in October. Both sites are hand harvested, taking grain and plant material from both treated and non-treated areas.
