Long-term, low-dose rate radiation exposure early in life might cause subsequent psychological stress and an increased risk of depression decades later.

More than 10 years after being informed of radiation exposure, the exposed populations were observed to have significantly lower perception of HRQoL even though no biomedical effects were apparent. It is recommended that appropriate intervention be carried out in the follow-up of post-event rehabilitation for the radiation exposed.

Being female and less than 12 years of age at disclosure were more significant predictors of HRQoL scores than the levels of radiation exposure among people exposed to protracted low-dose radiation. Further studies are needed to determine the psychological distresses, such as depression and anxiety, and their relationships in this case, especially for the most vulnerable young females.
