Doctors who are regularly exposed to X-ray radiation may undergo changes in their cells that protect them from the radiation they encounter, a new study suggests
On average, the interventional cardiologists were exposed to 4 millisievert (mSv) of ionizing radiation per year, those some exposures were as high as 8 mSv. The average person in the United States is exposed to about 3 mSvs per year from natural sources, according to the United States Nuclear Regulatory Commission.
BEIR 7
Possible stimulatory effects have been reported for radiation exposure, such as mobilization of intracellular calcium (Liu 1994), gene activation (Boothman and others 1993), activation of signal transduction pathways (Liu 1994; Ishii and others 1997), increase in antioxidants such as reduced glutathione (GSH; Kojima and others 1997), increase in lipoperoxide levels (Petcu and others 1997), and increase in circulating lymphocytes (Luckey 1991). The general thesis presented is that stress responses activated by low doses of radiation, particularly those that would increase immunological responses, are more beneficial than any deleterious effects that might result from the low doses of ionizing radiation. Although evidence for stimulatory effects from low doses has been presented, little if any evidence is offered concerning the ultimate deleterious effects that may occur.

The interventional cardiologists had higher levels of ROS in the plasma surrounding their blood cells than the other doctors, however, inside their red blood cells, both groups had the about the same levels of ROS.
That means that the cardiologists cells were producing more glutathione, and protecting the cardiologists' cells from seeing their ROS levels spike, Russo told MyHealthNewsDaily
