Abstract
Virtual Reality (VR) usage in research contexts has allowed for safer execution of experiments,
investigations, and training that involve real-time risk. At the University of Michigan’s
Radiological Health Engineering (RHE) laboratory, VR is being utilized as part of a video-game
project initiative to simulate scenarios that educate users on accurate radiological safety
protocols and sciences. This project, named DoseBusters, features scenario-based teaching
experiences that engage students with radiological substances and is meant to eliminate the
risk factors associated with unwanted radiation exposure associated with in-person laboratory
experiments. The VR application is primarily being developed by undergraduate research
students using the Unity game engine, using Meta Oculus Quest headsets for testing and
debugging. The training simulation features a guided experience through a room of radioactive
source materials and detectors, highlighting the characteristic signatures of different
radionuclides. Project additions include a sandbox tutorial option if users seek an experience
without the provided non-player character (NPC) instructor—a genre of video gameplay
characterized by a high degree of creative freedom, allowing players to explore the lab
independently and interact with the simulation in a non-linear fashion. In this sandbox
environment, users can pick up and observe the responses of detectors to a variety of
radioactive sources and shielding materials. Gaseous, scintillator, and semiconductor radiation
detectors are included, with some having spectroscopic capabilities. Virtual radiation dose
incurred by the player is also tracked throughout the experience using integrating virtual
electronic dosimeters. Future work will involve additional simulation incorporation of more
detector, source, and shielding assets, , as well as refining the equipment layout within the room
to create a more intuitive framework and professional experience. Further trials and feedback
from play testers will be conducted, informing our approach for the game’s next improvements
and future design optimizations.
