At the 2000 Summer Olympics in Sydney, Radan swam only in the 50 m freestyle. She achieved a FINA B-cut of 27.14 from the Akropolis Grand Prix in Athens. She challenged seven other swimmers in heat four, including Russian import Yekaterina Tochenaya of Kyrgyzstan, and Moldova's 16-year-old Maria Tregubova. Entering the race with a fastest-seeded time, Radan faded down the stretch to pick up a fourth spot in 27.70, almost a full second below the leading time set by Tochenaya. Radan failed to advance into the semifinals, as she placed fifty-third overall out of 74 swimmers in the prelims.
