Radiation detectors at Dallas-Fort Worth and Chicago O’Hare airports were triggered when passengers from flights that started in Tokyo passed through customs, the New York Post reported.

Tests at Dallas-Fort Worth indicated low radiation levels in travelers’ luggage and in the aircraft’s cabin filtration system; no passengers were quarantined, the newspaper said.

Details of the incident at O’Hare weren’t immediately clear, the Post said.
