To measure exposure of low energy X-rays with a free air chamber,the range of X-ray energy is from 2 to 12keV. Based on the X-ray transmission,attenuation and energy transfer in the air, the X-ray exposure at the entrance window of the ionization chamber were calculated. Then both the karma in air and the X-ray flux were derived. The change of the X-ray exposure with increasing the X-ray energy and the measurement of multichromatic (white) X-ray exposures were also discussed,respectively.
