In this study, we evaluated the educational effectiveness of training by reviewing recorded data on contamination survey techniques and real-time display feedback. An optical flow (OF) sensor and a distance sensor were used to measure the speed and distance, respectively. The sensors were mounted on a radiation measuring device, and the contamination survey techniques of the 12 participants were recorded. The recorded data and real-time technique feedback was used to conduct training, after which the participants performed contamination surveys once more. Speed and distance both significantly decreased after training, with speed dropping from 4.70 to 3.45 cm s−1 and distance decreasing from 1.16 to 0.90 cm. Additionally, variations during surveys showed a significant reduction.
Key words: optical flow / education / radioactive contamination survey
