While the new results in cell cultures are potentially concerning, the study's authors stress that translating radiation's effects on lab-grown cell cultures to effects in the body is premature. Future experiments using animal models will be necessary to determine the full effects of low-dose radiation, and whether its use in medical imaging has an impact on patient health. If the same phenomenon does occur inside the body, then doctors may need to take into account levels of extraneous DNA, such those resulting from a long-term viral infection, when assessing a patient's risk from a procedure that requires radiation.

That study is a start only.
