Author Correction: Reconstruction of residents’ thyroid equivalent doses from internal radionuclides after the Fukushima Daiichi nuclear power station accident

The Original Article was published on 27 February 2020

Correction to: Scientific Reports https://doi.org/10.1038/s41598-020-60453-0, published online 27 February 2020

This Article contains errors in the Methods section under subheading ‘Estimation of TED via inhalation’ where,

FC is a correction factor for the dose coefficient because iodine uptake rate is 18.5% (SD 6.0%), lower than the 30% in the ICRP thyroid model, while thyroid volume in Japanese does not differ from that of ICRP reference man18. DFshelter is a decontamination factor to reflect sheltering. In the present study we set FC to 0.62 (=18.5/30) and DFshelter to 0.5, and the combined uncertainty interval of these two factors is simulated as described below.”

should read:

The Article also contains an error in equation (3) in the Methods section under the subheading ‘Estimation of TED via ingestion in Iitate village’ where,

$${{\rm{E}}}_{{\rm{Thyroid}}({\rm{ingestion}})}=\mathop{\sum }\limits_{{\rm{j}}}^{14}{{\rm{V}}}_{{\rm{tap}}}\times {{\rm{C}}}_{{\rm{tap}}}\times {{\rm{e}}}_{{\rm{ing}}/{\rm{thy}}}\times {\rm{FC}}\times {\rm{Sf}}\times \frac{{{\rm{X}}}_{{\rm{j}}}}{3}$$

should read:

$${{\rm{E}}}_{{\rm{Thyroid}}({\rm{ingestion}})}=\mathop{\sum }\limits_{{\rm{j}}}^{14}{{\rm{V}}}_{{\rm{tap}}}\times {{\rm{C}}}_{{\rm{tap}}.{\rm{j}}}\times {{\rm{e}}}_{{\rm{ing}}/{\rm{thy}}}\times {\rm{FC}}\times {\rm{Sf}}\times \frac{{{\rm{X}}}_{{\rm{j}}}}{3}$$

In addition, there is a typographical error in the Methods section under subheading ‘Uncertainty of correction factors’ where,

“Likewise, the combined uncertainty of FC and Sf in formula (2) was simulated by setting FC as having a normal distribution with (18.6 +/−6.0)/30% and Sf as having a binomial distribution with denominator 100 and expected proportion 0.3.”

should read:

“Likewise, the combined uncertainty of FC and Sf in formula (3) was simulated by setting FC as having a normal distribution with (18.6 +/−6.0)/30% and Sf as having a binomial distribution with denominator 100 and expected proportion 0.3.”

Finally, this Article contains errors in References 18 and 28 which are incorrectly given as:

18. Kudo, T. et al. Determination of the kinetic parameters for 123I uptake by thyroid, and thyroid weights and volumes, In present-day healthy Japanese volunteers. Health phys. In press (2019).

28. Fukushima Revitalization Station (Fukushima Prefecture Government).
