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
“Our findings clearly emphasize for the first time that exposure to a level of radiation which is considered ‘safe’ by regulatory standards for interventional cardiologists can induce a profound biochemical and cellular adaptation,” Russo said in a news release.
I think that its important to realise that the people publishing this research are not suggesting that anyone is bomb proof, or could survive , in any eventuality , Fukushimas highest radioactivity areas due to adaptations or minor mutations caused by low level exposure.
