Al-Qaradawi's research centers on positron and radiation physics and its applications. She led the efforts in establishing the first slow positron beam facility in the Middle East region, known as the "Qatar Positron Beam". The positron beam facility incorporates a Na-22 source and Tungsten mesh moderator, and is a magnetically guided beam with energies of 0-30 keV. has established an environmental radiation measurement laboratory in Qatar University due to her interests in nuclear and radiation physics.
