Description
The safe, sustainable planning and operation of facilities and activities, such as nuclear installations and uranium facilities in regions characterized by arid or semi-arid climate, requires science-based knowledge on radionuclides fate and transfer processes, and related data for radiological environmental impact assessment (REIA) within these regions. However, although significant work has been undertaken for temperate climatic conditions, major knowledge and parameter data gap has been identified for arid and semi-arid regions under the IAEA’s Modelling and Data for Radiological Impact Assessments II (MODARIA II) programme (https://www-ns.iaea.org/projects/modaria/modaria2.asp). It is important to acknowledge that there are differences in soil and crop types, soil physicochemical characteristics, agriculture practices and food consumption habits in arid areas in different parts of the world, in comparison to temperate or tropical regions. Therefore, the key fate and transfer mechanisms governing the transfer of radionuclides between different environmental media and within the food chain can differ. Moreover, the rise in global temperatures has led to increasing arid and desert-like areas in many regions worldwide, with significant changes of soil and crop properties.The Expert Group under MODARIA II Working Group 4 (WG4):Transfer Processes and Data for Radiological Impact Assessment, Subgroup 3 (SG3) on Transfer Parameters in Non-Temperate Systems proposed that it would be beneficial to continue this work within the framework of a Coordinated Research Project (CRP). The overall objective of this CRP is to improve REIA for arid and semi-arid regions in support of effective decision-making and to ensure the protection of the public and the environment. Soil-to-plant transfer parameter datasets derived according to a standard protocol and experimental conditions will be established for radionuclides important for REIA, and for plant groups specific to arid/semi-arid regions, to address the existing gaps in data.
Objectives
To contribute to the improvement of radiological environmental impact assessments for arid and semi-arid regions in support of effective decision-making and to ensure the protection of the public and the environment
Specific objectives
To establish a protocol and guidelines for determination of soil-to-plant transfer parameters for the most important food-plant groups in arid and semi-arid regions to ensure the representativeness of data (including experimental set-up, sampling and data evaluation) and to fill in the gaps identified from th
