Radiation Protection of Wildlife: Modelling the Exposure and Effects

This publication summarizes the activities of the Working Groups that considered the application of modelling to estimate radiation exposure of wildlife and the effects of such exposure on wildlife populations. It assesses the fitness for purpose of available models and tools and proposes models and tools for use by assessors. It also addresses modelling approaches for estimating population dynamics and radiation dose effects on populations of wildlife.

This publication, produced as part of the International Atomic Energy Agency's (IAEA) Modelling and Data for Radiological Impact Assessments (MODARIA I and MODARIA II) programmes, serves as a comprehensive summary of the activities undertaken by the Working Groups that delved into the application of modelling techniques to estimate radiation exposure in wildlife and the subsequent impacts on these populations. The assessment of the suitability of existing models and tools for estimating wildlife exposures is conducted, leading to the proposal of various models and tools for use by assessors. Based on the rigorous evaluations carried out, it is concluded that the commonly used models generally possess the necessary fitness for purpose for conducting screening-level assessments. Furthermore, the publication addresses modelling approaches for estimating population dynamics and the effects of radiation on wildlife populations, providing valuable insights into this field.

Introduction:
The IAEA's MODARIA I and MODARIA II programmes aimed to enhance the understanding and application of modelling techniques for estimating radiation exposure in wildlife and its effects on populations. These programmes involved the collaboration of experts from various countries and disciplines, including wildlife biologists, ecologists, radiologists, and modellers. The publication summarizes the key findings and outcomes of these efforts.

Working Group Activities:
The Working Groups involved in the MODARIA I and MODARIA II programmes conducted extensive research and analysis to evaluate the suitability of existing models and tools for estimating wildlife exposures. They reviewed and assessed a wide range of modelling approaches, including deterministic and stochastic models, as well as data-driven models and machine learning algorithms. The Working Groups also considered the availability and quality of data required for modelling wildlife exposures and their effects.

Model Fitness for Purpose:
The assessment of the fitness for purpose of available models and tools was a critical aspect of the MODARIA I and MODARIA II programmes. The Working Groups evaluated the models based on their ability to accurately represent the complex biological and environmental processes that govern radiation exposure in wildlife. They considered factors such as species-specific characteristics, radiation sources, exposure pathways, and dose-response relationships. Based on the evaluations, a number of models and tools were proposed for use by assessors.

Population Dynamics Modelling:
In addition to estimating wildlife exposures, the MODARIA I and MODARIA II programmes addressed modelling approaches for estimating population dynamics and the effects of radiation on wildlife populations. The Working Groups explored the use of demographic models, life-history models, and population dynamics models to simulate the effects of radiation on wildlife populations over time. They considered factors such as population growth rates, survival rates, migration patterns, and reproductive behaviour.

Conclusion:
The MODARIA I and MODARIA II programmes have made significant contributions to the field of modelling and data for radiological impact assessments. The publication summarizes the activities of the Working Groups, highlights the key findings, and provides recommendations for future research and development in this area. The proposed models and tools can be valuable resources for assessors, policymakers, and stakeholders involved in wildlife conservation and management.

Future Directions:
While the MODARIA I and MODARIA II programmes have provided valuable insights into the application of modelling to estimate radiation exposure in wildlife and its effects on populations, there are still opportunities for further research and development. Future research should focus on improving the accuracy and reliability of modelling approaches, particularly for species with limited data availability. Additionally, more attention should be given to developing modelling tools that can be easily accessible and used by a wide range of stakeholders, including those with limited technical expertise.
