Child and Adult Thyroid Monitoring After Reactor Accident
A nuclear power plant accident will cause uncontrolled release of a large amount and complex mixture of radionuclides; however 131I generally makes the largest dose contribution. After the Chernobyl accident, many citizens received thyroid doses exceeding 1 Gy due to radio-iodine intakes and more than 6 000 thyroid cancers (mostly in children) were attributed to radio-iodine intakes. After the Fukushima accident, about 98% of the effective dose received by emergency workers was attributable to radio-iodine intakes.
Following a large scale nuclear accident, or even a small accidental release, citizens will expect to be individually monitored rather than rely on calculated dose. This project focuses on post-accidental 131I measurement in the thyroid, particularly for children.
This project focuses on the monitoring strategies and assessment of thyroid doses resulting from intakes of radio-iodine. Monitoring strategies will address monitoring of children and adults, required capabilities and existing gaps. Strategies will also address harmonization of measurements and dose assessment to be done by national authorities, within the European Union and neighbouring countries.
This project relies on a review of existing European means, on two thyroid measurement inter-comparison circuits, focusing on children, on Monte-Carlo based device calibrations and on the development of emergency oriented dose assessment methods.
Identified gaps such as the children case will be solved and other potential gaps will be revealed.
The main outcome of the project will be guidelines based on practical experience and on the comparison of existing and required means. Guidelines will also benefit from the inputs of the civil society.
Based on the work of the other work packages, on literature review and on the experience of the participants the following guidelines will be made publically available:
The guidelines and the report of work packages will be made publically available on June 2017.
Conclusions will be presented in conference and peer-reviewed articles
