 note = {The absorbed dose rate in air was measured at the National Institute for Fusion Science (NIFS) site before the deuterium plasma experiment in the Large Helical Device (LHD). A pocket survey meter was used for the measurement of 1 cm dose equivalent rates in units of μSv h−1 and these results were converted to absorbed dose rates in air (units: nGy h−1) using a conversion factor. The arithmetic mean of the absorbed dose rates in air based on 257 measurement points at NIFS site was 45 nGy h−1. The result of this study suggests that the building material and/or paving stone enhance the dose rates in air at the NIFS site.},
