Quantitative risk assessment of radiocaesium in Japanese foods


This assessment was carried out in 2021 by the Food Standards Agency as part of the evidence base to inform decisions on import controls for Japanese food following the Fukushima nuclear accident, which occurred in 2011. The risk assessment has been published for information purposes only. The risk assessment estimates the radiological risk to human health from consumption of foods and beverages imported from Japan. Other considerations are out of the scope of this assessment. This assessment was produced by a team of FSA radiological risk assessors with guidance from the UK Health Security Agency (UKHSA). Independent peer review was provided by the Committee on Medical Aspects of Medical Aspects of Radiation in the Environment (COMARE), a Department of Health and Social Care (DHSC) expert committee which provides independent advice to all government departments and agencies.
