  Vorrichtung zur Bestimmung der Durchdringungsfähigkeit von Strahlen. 



   Zur Bestimmung der   Durchdringungsfähigkeit   von Strahlen, insbesondere Röntgen, strahlen, bedient man sich einer Vorrichtung, die aus einem treppenartig gestalteten Stollen verschiedener, der Stufenhöhe der Treppe entsprechend zunehmender Dicke auf. weisenden und einem an die Treppenanordnung angrenzenden Teile überall gleicher Dicke bestehen. Das Bild, welches die Strahlen beim Durchlaufen dieser Vorrichtung auf einem Fluoreszonzschirm oder auf der photographischen Platte erzeugen, zeigt ein Gebiet homogenen Farbentones und daran angrenzend eine Reihe von Feldern untereinander verschiedener Helligkeit.

   Das unmittelbare Aneinandergrenzen dieser verschieden hellen Farben-   töne   aneinander und an das homogene   Verg ! eichsgebiet   gibt, zumal wenn es sich, wie bei der Anwendung der Vorrichtung stets, um geringe    HelligkeitsulJtoschiede handelt,   Anlass zu optischen   Täuschungen   und damit zu Beobachtungsfefilern.

  Device for determining the penetrability of rays.



   To determine the penetration ability of rays, in particular X-rays, a device is used, which consists of a stair-like shaped tunnel of different thicknesses that increase according to the step height of the staircase. pointing and a part adjacent to the staircase arrangement consist of the same thickness everywhere. The image which the rays produce when passing through this device on a fluorescent screen or on the photographic plate shows an area of homogeneous hues of color and adjacent to it a series of fields of different brightness.

   The direct juxtaposition of these different light shades of color to each other and to the homogeneous Verg! calibration area, especially if, as is always the case with the use of the device, there is a matter of low brightness differences, giving rise to optical illusions and thus to observation filters.



   This is remedied by the invention, according to the areas of the device that are practically impermeable to radiation at the boundaries of the areas of the device which have different thicknesses or different radiation permeability - viewed in the direction of the radiation, i.e. measured perpendicular to the direction of radiation.
 EMI1.1
 
An example embodiment of the new model is shown in the drawing in a perspective view.

   The step-shaped part a is here for
 EMI1.2
 Another important advantage is that the secondary beams emanating from each of the parts delimited by the transverse walls do not apply to the sensitive parts and can lead to measurement errors there. PATENT CLAIMS:
