This presentation introduces the technique for 3-D mapping of dose-rate distributions in radiation-work environments. By combining a survey meter and Structure from Motion (SfM) technology, the values of the dose rate acquired by the survey meter are mapped on the 3-D virtual model of the work environment reconstructed by SfM. In addition, this method makes it possible to map the dose rate in the work environment while freely moving the survey meter. If the distribution of the dose rate can be visualized three-dimensionally, it is possible to reduce the exposure dose of workers and contribute to the planning of an efficient work plan.
