After more than a decade of research, PCAire Inc. has developed and coded algorithms that can accurately predict the radiation levels during jet aircraft flight. These algorithms are a result of assembling one of the most complete data set of measured cosmic radiation levels at jet aircraft altitude. The result is the PCAire code which is available through a subscription to this Internet site. Individual users are able to calculate and track their own radiation dose, and airlines can install the PCAire.sys module on their servers and calculate the dose to their aircrews. PCAire Inc. is dedicated to offering the most reliable services through implementation of high quality science. Our team includes scientists and researchers who understand cosmic radiation dosimetry and who continue to advance the knowledge in this field.
