A Location-Based AR Application to Display Cosmic Radiation Dose Rates on Flying Aircrafts in Real Time

摘要

The purpose of this study was to develop a prototype of a new radiation education tool of a location-based AR application that displays cosmic radiation (cosmic rays) dose rates on flying aircrafts in real time. After the Fukushima nuclear disaster, radiation education has been started again in elementary and junior high schools after 30 years' absence to teach radiation protection. The unit of the dosimetry is defined by Sievert and primary school children are not familiar with the units. It's necessary to develop a new educational tool to teach dosimetry caused by natural radiation for primary school children. The new educational tool was focused on flying aircraft above cities. Cosmic radiation has a feature of altitude dependency. If the learner can monitor the dosimetry in flying aircraft in real time, it will be expected to learn the relationship between the amount of the dosimetry unit and a lower limit for health damage in daily life intuitively. Besides, learners may gain interest in astrophysics and particle physics by using the tool. In this paper, an overview of the new tool is described and the approximation calculation method to estimate the dosimetry in flying aircraft is compared with JISCARD. As the result, the approximation calculation method was verified for the tool for show the dosimetry in flying aircrafts.
