Transfer parameter data are essential inputs to models for radiological environmental impact assessment and are used to quantify the extent of movement of radionuclides from one environmental compartment to another, relevant for estimating the transfer of radionuclides through food chains to humans. International data compilations (i.e. transfer parameter data for temperate environments from the IAEA Technical Reports Series No. 472) have been frequently used by regulators and professionals in radiological impact assessment for dose estimations when site-specific data are not available.
Description of Dataset Content
This international compilation of radionuclide and stable isotope soil-plant concentration ratio values for tropical environments is an output of IAEA’s Modelling and Data for Radiological Impact Assessments II (MODARIA II) programme (2016–2019) and is based on the Köppen-Geiger climate classification (BECK et al. 2018). The IAEA’s MODARIA II tropical dataset is associated with IAEA’s TECDOC-1979: Soil-Plant Transfer of Radionuclides in Non-Temperate Environments (2021).
The dataset contains over 7000 records. Each record includes a concentration ratio value and/or plant and soil concentrations, provided in a consistent way, from which a concentration ratio value can be calculated. Where available, environmentally relevant information is included with each record to allow categorization of the plant and soil data into more refined subsets.
The dataset includes information for over 100 plant species, including many that are common crops and staple foods in tropical environments. Data are included for all measured plant compartments, including both the edible and inedible parts of the plant.
Information in the dataset is organized into 41 fields, with individual lines in ascending order of their source reference. These headline fields are described in the associated ‘Explanatory Information’ file, while a description of the dataset content can be found in the ‘Dataset content‘ file.

Acknowledgement
The IAEA wishes to express its gratitude to C. Doering (Australia) for compiling this comprehensive dataset as part of the activities of Working Group 4 of the MODARIA II programme, led by B. Howard (UK). The IAEA also gratefully acknowledges the valuable contributions of J. Twining (Australia) and S. Rout (India).
How do I Search for Data?
The ‘Explore’ tab, on the right corner of the first page, allows users to explore the data online (by selecting the ‘Preview’ tab or by accessing the CSV-type file under ‘Data and Resources’) or to retrieve the whole dataset as a CSV-type file by selecting the ‘Download’ tab.
To search for data in the online preview mode, use the filter control panel on the left of the ‘Data Explorer’ page. Click ‘Download’ at the top right of the page to download the data as a CSV file.
