The study of “external” radiation called cosmic radiation that strikes the earth from anywhere beyond the atmosphere is of great importance in radiation protection. All human beings are exposed to an uncontrollable amount of cosmic radiation on the ground level. Those who travel in space, airline crews and frequent flyers are exposed to additional level of cosmic radiation during their trip but unfor-tunately many of them are not aware of this. This workcalculates the exposure of aircrews and fre-quent flyers to cosmic radiation during travel along some air routes to and from Nigeria. The effective dose was computed using a dedicated software CARI 6M, developed by US FAA.The study focuses on the significance of the in-flight exposure, assessment and estimation of in-flight exposure using the dedicated software and some ways of controlling the exposures so that airline crews and frequent flyers are not exposed to fatal levels of radiation.It was observed that the cosmic radiation doses re-ceived by passengers and crew members on board on flights from Lagos Nigeria to countries in Amer-ica were more than what they received en-route countries in Asia.

Abstract In this study, cosmic radiation doses were calculated for domestic and international flights departing from Istanbul and furthermore for domestic flights departing from Ankara using a software program called CARI-7A and also a mathematical method approach. Main parameters for calculating cosmic radiation are vertical cut-off rigidity, flight duration, latitude–longitude and altitude of the flight. Our calculation results agree with the measurements for domestic and international flights departing from Istanbul and Ankara.

To estimate Radiation doses received onboard aircraft to protect aircrew in accordance with the basic standard on ionization radiation protection and radiation source safety of China, we has developed a software called CARD used to calculate the effective radiation doses. A three dimension matrix is kernel part of the CARD, in the matrix preserves information about effective dose rates of cosmic radiation for retrieval is constructed. The data of matrix are based on results of simulation and measurements. The comparisons between the calculated effective dose using this tool and using CARI-6 respectively for various flights are carried out. The present analysis shows that for the cosmic radiation, this software is sufficient to ensure a precision on the dose estimate of flight.

Eu Directive

January 2000 saw the start of a collaborative study involving the Mullard Space Science Laboratory, Virgin Atlantic Airways, the Civil Aviation Authority and the National Physical Laboratory in a program to investigate the cosmic radiation exposure to aircrew. The study has been undertaken in view of EU Directive 96/291 (May 2000) which requires the assessment of the level of radiation exposure to aircrew. The project's aims include validation of radiation dose models and evaluation of space weather effects on atmospheric cosmic radiation levels, in particular those effects not accounted for by the models. Ground level measurements are often used as a proxy for variations in cosmic radiation dose levels at aircraft altitudes, especially during Forbush Decreases (FDs) and Solar Energetic Particle (SEP) events. Is this estimation realistic and does the ground level data accurately represent what is happening at altitude? We have investigated the effect of a FD during a flight from Hong Kong to London Heathrow on the 15th July 2000 and compared count rate and dose measurements with simultaneous variations measured at ground level. We have also compared the results with model outputs.
