Three Mile Island (TMI), located near Harrisburg, Pa., had a partial meltdown accident on March 28, 1979. During the […]
Low doses of radiation used in medical imaging lead to mutations in cell cultures
Common medical imaging procedures use low doses of radiation that are believed to be safe. A new study, however, finds that in human cell cultures, these doses create breaks that allow extra bits of DNA to integrate into the chromosome. Roland Kanaar and Alex Zelensky of Erasmus University Medical Center and Oncode Institute and colleagues […]
