This study explored the changes of space radiation dose rate both indoor and outdoor associated with a decontamination operation for a wooden house in a low dose area. As a result, the maximum space radiation dose rate measured at 1 m height from the floor inside the house before the decontamination operation was 0.19 µSv/h. The maximum space radiation dose rate after the decontamination operation was 0.12µSv/h. Furthermore, the results of a comparison of the space radiation dose rate between pre- and post-decontamination operation indicate a decrease in the rate at most measurement points, and the average reduction rate of the space radiation dose rate in the post-decontamination operation condition was around 20%.
