The primary standard for low-energy X-ray dosimetry measurements is the freeair ionization chamber. For some measurements, such as that of surface dose, the free-air ionization chamber is difficult or impossible to use. For these measurements the Bragg-Gray chamber (1-3) is a valuable instrument. A comparison of free-air ionization chamber measurements with Bragg-Gray chamber data using lowenergy X-rays is needed to verify the Bragg-Gray principle and establish the limitations on a Bragg-Gray chamber in this energy region. For the medium-soft X-ray energy region, Marinelli (4) expresses the BraggGray principle in the following form
