[Determination of total filtration and half attenuation layer in X-ray diagnostic units by relative radiation output].

Described is a relatively simple technique applicable to estimating the independent and additional filtration of X-ray images by the relative radiation output with a voltage generation range of 50 to 120 kB. It is shown as possible to determine the half-attenuation first layer in its aluminum equivalent and without using any aluminum filters. The suggested technique can be used in turn-over and regular tests of medical X-ray units as well as in their exploitation.
