How does PCAire calculate the dose?

Our research scientists flew a large radiation detector, sensitive to cosmic rays, on hundreds of flights, all over the world. The radiation field was recorded every minute along each of these flights. Analysis of this data led to the development of mathematical functions that matched the measurements for any flight, at any altitude and anywhere in the world.



The PCAire code uses these mathematical functions to calculate the dose to a person on a given flight. For each flight that is entered, the code takes into account the date, time, and flight path and recomputes the radiation field during that flight. The results are summed and recorded in your dose profile.
