Believe it or not, flying exposes you to an increased amount of radiation coming from space. A single flight across the ocean is no big deal but long-term elevated radiation exposure can increase your risk of some kinds of cancer, and it’s why workers that are exposed to elevated levels of things like X-rays are monitored to make sure exposure is kept to a minimum.
It got me thinking, while I listened to the slow and steady suction of spit from my oral cavity, “I wonder if Lois Lane, would have to wear a radiation safety badge?” I am totally unsure about the radiation output Continue reading
