Radiation also lowers the immune system. It’s critical to keep our immune system strong so we can fight the pathogens and battle the toxins that we come up against every day. When we fly, we already get a tremendous amount of radiation exposure. There’s still nuclear fallout floating in ...
Workers may also be exposed to natural sources of radiation such as miners exposed to radon and aircrew members exposed to cosmic radiation while flying. Recommendations and regulations on radiation protection of workers were first developed at the beginning of the 20th century. The International ...
The exposure astronauts experience in an orbital environment like the International Space Station is much less than they would experience on a trip to the moon, but it’s still enough to affect the crew. “Sometimes you can see cosmic rays hitting your eyeball, and you realize that’s radiat...
Nuclear radiation has powerful benefits — nuclear power generates electricity while nuclear medicine detects and treats disease — but it also has significant dangers. Radiation Exposure in Daily Life In our everyday lives, we are constantly exposed to radioactive materials, including beta and gamma...
A 53-year-old flight attendant in South Korea, who spent about 1,022 hours flying each year, passed away due to cancer . A South Korean court (法庭) connected his death to a high level of exposure (暴露) to cosmi...
Cytokines evoke vast inflammatory and anti-inflammatory signaling in the immune system, and regulation of their plasma levels is critical for proper immune function. Combined exposure rodent models indicate dysregulated cytokine levels similar to changes observed in astronauts’ plasmas collected while in ...
Everyday Radiation Exposure Is A Tiny Health Risk For the natural sources of ionizing radiation, actually the biggest chunk of that tends to come from radon, which is a radioactive material that is present in the air. It can become a concern when it builds up in low-lying areas of homes...
where the Centers for Disease Control and Prevention estimates smokers are 15 to 30 times more likely to get lung cancer than non-smokers. But we also don’t have as much research to draw on for cell phone exposure, and we know that usage is climbing dramatically. Many of us plan to us...
The extent of exposure depends on several factors, such as altitude and the efficiency of your home ventilation system. You can put a radon detector in your home to keep track of your exposure. Perhaps another source of radiation that comes to mind is from medical scanning. Generally, the ...
Radiation exposure in the first few months of life may be the most serious in causation of later breast cancer. In fact, irradiation of the breasts between age 0 (newborn) and age 9-years may cause MANY-fold more cases of breast cancer, over the subsequent lifetime, than does irradiation...
