[A comparison of the radiation dose from film and xeroradiography (author's transl)].

Using a LiF dosimeter, comparative measurements were carried out on film mammography and xeromammography on surface and exit dose to the breast and scatter at the level of the gonads. Exit dose at 200 to 330 mR was approximately the same for both methods; incident dose at 6,800 mR for film mammography was significant higher than for xeromammography at 3,800 mR (Mo tube) or 1, 200 mR (tungsten tube). Scatter at the level of the gonads for all three methods was between 4.4 and 12.8 mR. For xeroradiography of the knee joint, the radiation dose of 466 mR was approximately three times that for a film technique (160 mR).
