Dose Rate and Flux Measurements During a Travel from Bulgarian Antarctic Base on Livingston Island to Sofia, Bulgaria

The radiation risk spectrometer-dosimeter Liulin-AA performed observations in the Bulgarian Antarctic Base on Livingston Island.The battery-operated device also did continues measurements at the back trip from Livingston Island to Sofia, Bulgaria between 24 of February and March 9, 2024.Different radiation and environment conditions were detected during this journey.The latter starts with few days measurements in the Bulgarian Antarctic Base and includes: four trips by car, one travel by ship, four aircraft flights, one of which is crossing the magnetic equator, one travel by bus and two stays in hotels in Punta Arenas, Chile and Buenos Aires, Argentina.The lowest dose rates were measured during the trips by car.The dose rates during the ship travel were smaller than the dose rates on the ground.The dose rates registered in a bricks building in Sofia were higher than the ground dose rates.As expected, the highest dose rates were registered during the aircraft flights.The different dose rates and spectra are described and analyzed in this paper.
