We analyzed dose rate data of space neutron and gamma radiation during several flight with various destinations, i.e. Jakarta – Kupang, Kupang – Jakarta, Jakarta – Pontianak, and Pontianak – Jakarta. Data were collected using personal radiation dosimeter (RadEye for neutron and Dosicard for gamma radiation) during flights from take off until landing at the destination airports. As expected, the higher the aircraft from sea level, the radiation received are higher also, but the behaviour of the neutron and gamma radiation are different. The neutron radiation received are more erratic compared with that of the gamma radiation. We found the correlation between the height of the aircraft and neutron and gamma radiation dose rates with correlation coeficient values of 0.89, 0.86, 0.90, 0.87 respectively for neutron radiation and 0.91, 0.95, 0.84, 0.88 respectively for gamma radiation. We found the empirical relations between latitude and dose rates of neutron and gamma radiation in the height of 35.000 feet from the sea level as Dn = −0.034 Lat + 1.036 for neutron dose rates and Dg = −0.027 Lat + 0.636 for gamma radiation dose rates.
