Travel by Air and Radiation

The average flight height of aircraft is 30,000 feet, ie 10,000 meters. The aircraft cabin does not have the ability to protect passengers from cosmic radiation. Anadolu Medical Center Radiation Oncology Specialist Assoc. Dr. Metin Güden emphasizes that passengers are affected by both cosmic radiation and radiation emitted by the sun while flying, and this effect depends on several factors such as flight times, altitude, flight routes and sun activity.Flight times: The longer they fly, the more radiation they get. Height: The higher they fly, the more radiation they are exposed to.Flight routes: Those flying at the same height and at the same time in the equatorial region are affected by less radiation than flying near the poles. Activity of the Sun: The activity of the sun is constantly changing. The ratio of radiation that affects passengers between two flights made at the same route and the same height at the same time is different depending on the activity of the sun.Assoc. Dr. Metin Güden explains that the radiation received during pregnancy causes negative effects on the child under three headings. stillbirths and miscarriages. They usually occur when they are affected by radiation during the first trimester of pregnancy. The second is that the baby has organ anamolysis. This usually occurs when they are affected by radiation during the second trimester of pregnancy. The third is mental retardation and developmental disability. Radiation received during the last three months does not cause stillbirth or organ anomaly, but mental retardation and developmental disorder may occur. Dr. Metin Güden explains that under normal human natural living conditions, he receives 1.4 - 2.7 mSv radiation per year and, although not a standard, the acceptable dose for a pregnant woman to take an extra year is 1mSv. For example; If a person travels seven times at 10,000 meters between New York and Athens, he receives a total dose of 1 mSv of additional radiation. According to this; If a woman travels between continents with at least seven trips during pregnancy within one year, she may remain within acceptable limits. As is known, high-energy rays form free radicals in the body. Antioxidants are the way to prevent the harmful effect of these free radicals. These antioxidants are very high in green vegetables and fruits. There are also preparations prepared in tablet form. By using them, it is possible to significantly reduce the harm to the body from the harmful rays of radiation. This solution applies to all people, not just pregnant women. It is also possible to avoid night-time radiation and to reduce the radiation exposure by choosing night flights.
