Özet
Background and Aim: Flight crew and passengers are exposed to cosmic radiation from outer space in flights. We want to investigate whether or not cumulative radiation dose could exceed the teratogenic level of radiation for pregnant with simulation based study. Materials and Methods: We performed a simulation based study for calculating cumulative radiation dose with radiation calculator software. Cosmic radiation exposure of a crew working 110 hours per month between Istanbul and Batman (route 1) in Turkey at an average altitude of 30,000 feet and one working 110 hours per month between Istanbul and San Francisco, CA (route 2) at an average altitude of 35,000 feet was calculated. These flights are considered the longest and highest domestic and international flights in and from Turkey. Exposure was estimated for cosmic ionizing radiation with the galactic cosmic radiation calculator program of the Federal Aviation Administration Civil Aerospace Medical Institute. Results: If an air crew flew 110 hours a month on routes 1 and 2, the highest dose of cosmic radiation would be 0.20 and 0.56 millisieverts (mSv) per month, respectively. Domestic flights do not exceed the recommended monthly limit of 0.5 mSv. Flight time on route 2 flights exceeded the recommended pregnancy limit of 0,5 mSv accordingly the National Council on Radiation Protection and Measurement recommendations. Conclusion: Simulated cumulative radiation dose of a pregnant crew who fly 110 hours at 30000 feet in a month in Turkish Domestic flight is not exceed teratogenity level for fetuses with software calculation. Calculation of simulated cumulative radiation dose with international flight with flying 110 hour at 35000 feet in international flights for a pregnant crew could exceeds teratogenity level for fetuses.
