The KIRAMS establishes radiological emergency institutions and provides training for emergency medical agents. However, because of the uniqueness of radioactive accidents, the current training program has a limitation in the realistic description. Therefore, training programs based on virtual augmented reality technology that can describe radiological emergencies are required. In this study, the contents of practical training for decontamination of radiation-contaminated patients as a part of radiation disaster prevention personnel training using VR simulator are developed.

Environments and devices required for treating patients with complex radiation damage are made visible using VR simulator to enable practical training of techniques and practices that will be required in actual radiation emergencies or training. The VR decontamination training content uses three Point tracking techniques to calculate the location of the head-mounted display device and the hand to visualize the movements. Additionally, Universal Render Pipeline technology was used to develop realistic visualizations of situations.

In this study, VR decontamination treatment practice content was developed, which allows a single trainee to go through the entire treatment process of treating radiation-contaminated patients. The radiation-exposed patient’s treatment process is composed of nine subprocesses, including wearing personal protective equipment, obtaining samples from openings, taking measurements, cleaning contaminated injuries, and so on. A checklist user interface was used to enable trainees to check their progress. The trainee can practice patient treatment with a controller while using VR decontamination treatment content. Additional functions such as narration, sound effects, animation, and so on were added to high educational effects.

In this study, VR decontamination treatment content was developed using VR training simulator to practice the treatment of radiation-contaminated patients. The results of this study will contribute to fostering the workforce response to radiation through efficient education using a VR training simulator, as well as promoting the use of radiation safety regulations.
