Artemis-2 Mission Quantifies Space Radiation Risks
NASA's Artemis-2 mission aims to quantify the health impacts of radiation exposure during space travel. Molecular pathologist Professor Jerry Thomas discusses the difficulty of researching the effects of low-dose radiation exposure. High doses cause obvious sickness and death, but research is harder for doses below 100 millisieverts. The average American receives approximately six millisieverts of radiation annually. The average person in the UK receives roughly two millisieverts per year. Researchers note that it is difficult to determine the health effects of radiation at levels below 100 millisieverts. The study focuses on the impact of these tiny, low-level doses. Current data indicates that radiation is present in small doses everywhere. Safety standards for space travel are being compared to the more stringent regulations used for nuclear power plants.

“The problem is that at high doses it's pretty obvious that radiation is responsible for causing sickness and death. But low doses are what hundreds of thousands of people were exposed to, and that's much harder to research.”
