title: [A simple method for estimating cosmic radiation effective dose rate].
abstract: OBJECTIVE
  To study a simple method for estimating cosmic radiation effective dose rate for aircrew.
  
  
  METHODS
  Using a new program by written in Object Pascal language on PC in Windows operation system on the basis of an algorithm designed in this paper, cosmic radiation effective dose rates at various altitudes and latitudes were calculated and compared with those obtained by using CARI-6 and FLUKA.
  
  
  RESULTS
  The calculated results by using the simple method agree remarkably with those calculated by using CARI-6 and FLUKA, in three groups of data compared with CARI-6, differences are within 25% for 76%, 71% and 100% of the data respectively; in the group of data compared with FLUKA, differences are all within 20%.
  
  
  CONCLUSIONS
  The simple method is applicable in estimating cosmic radiation effective dose rate for flight altitude of 7000 to 20,000 m.
