We created a new radiation protection learning method for nurses and studied the educational effects. We made a four-beds in one room and measured the scattered radiation caused by X-ray photography of the chest and abdomen of the phantom in this room. We created a distribution map of scattered radiation with measured values. Projection mapping was successfully applied for the scattered radiation distribution map. We held a workshop using projection mapping for nursing students. In the workshop, nursing students were able to visually observe the distribution of scattered radiation. Nursing students who participated in this workshop were able to gain knowledge about not only radiation and radiation exposure, but also avoiding radiation exposure and maintaining an appropriate distance that a patient did not worry. In addition, this workshop increased nursing students’ motivation to learn about radiation. Therefore, we considered the workshop using projection mapping to be effective for nursing students’ radiation protection education.
