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.

Background and Purpose: The degree of stress of refugees who evacuated the prefecture due to the Fukushima Nuclear Power Plant accident concomitant with the Great East Japan Earthquake (GEJE) was evaluated.

Method: An anonymous self-registered investigation based on 34 indicators related to refugees’ psychology (ST34) was performed. Subjective stress, both immediately after the GEJE and three years later, were quantified by VAS method, the difference was calculated, and multiple regression analyses (MRAs) aiming at each were carried out. The explanatory variables were taken as ST34, and 11 factors were extracted by factor analysis.

Results: The total number of respondents was 859 (recovery rate 21.0%), and Cronbach’s α of ST34 met the reliability standard of 0.8. In MRAs for each item of the ST34, only relocation was correlated with a decrease in stress. Of the 11 factors, those that saw an increase at the p<0.001 level immediately after the earthquake were human relationship changes, mobility, sickness, and taking out loans.

Discussion: Unlike life events in a general life, extraordinary events such as the death of close relatives, the collapse of houses, etc. occur at almost the same time in the event of a major disaster. For this reason it was confirmed that the degree of subjective stress increases additively due to simultaneous overlap of serious events.

This study aimed to identify people's perception when illustrations were attached to the detection unit of a Geiger–Mueller survey meter. Another aim of this study was to ascertain the impact of the measurement efficiency on the measured value when illustrations were attached. A questionnaire using the semantic differential method was circulated to 46 nursing students. In the devised version, the use of illustrations enhanced the “cheerful” image and provided relief from the “tense” image. The sealed cobalt-60 sources were measured using a Geiger–Mueller survey meter fitted with illustrations to investigate their impact on measurement efficiency. The impact on the measurement efficiency ranged from 1% to 9%. A suggestion was provided to ascertain an additional reading in the manner prescribed via illustrations if the measured value was approximately 90% of the standard. Attaching illustrations appeared to be effective for relieving tension among the study subjects when measuring radiation.
