Doctors whose bodies are regularly exposed to x-rays may be adapting at the cellular level to protect themselves against radiation, according to a new study. The research hints that humans could adapt to withstand radiation exposure.
In a small study, interventional cardiologists, who perform heart operations using catheters guided by x-rays, had higher levels of hydrogen peroxide in their blood, which indicates potentially harmful changes. But they also had higher levels of an antioxidant that protects against cell damage, and their white blood cells had more of an enzyme involved in programmed cell death.
