Dose reduction in the low-energy X-ray diagnostics of extremities.
The authors determined the surface absorbed dose (Ds = 67-68 mGy) and the average absorbed dose (Dav = 13-15 mGy) by means of non-screen film radiography of the extremities. The authors recommend the use of xeroradiography (with a tungsten anode tube) or, first of all, a rare-earth screen - film combination (e.g. Kodak min-R + Nuklearmedizin NMB film). The two methods permit the dose values to be decreased by a factor of about 4 and 15, respectively. The dose values are smaller, at least for the 8 cm thick tissue equivalent phantom, when a tungsten anode is used instead of a Mo anode.
