Ein strahlenempfindliches Festkörper-Meßelemeni 1, beispielsweise ein quaderförmiges Stück ausA radiation-sensitive solid-body measuring element 1, for example a cuboid piece
Die Erfindung betrifft ein Personendosimeter zum Phosphatglas, ist in einer Kunststoffmasse 2 eingebetenergie- und richtungsunabhängigen Messen von 35 tet und nach der dem Körper abgewandten Seite mit Quantenstrahlung mit einem strahlenempfindlichen einem kugelförmigen Metallfi'ter3, z.B. aus Zinn, Festkörper-Meßelement, das mit Abstand von einer umgeben, welches nach außen konisch erweiterte, zyannähernd kugelförmigen, perforierten, die Strahlung linderförmige Bohrungen 4 aufweist. Auf der dem in Abhängigkeit von ihrer Energie unterschiedlich Körper 8 der benutzenden Person zugewandten Seite stark absorbierenden Metallhülle umschlossen ist, *o ist das sonst im wesentlichen kugelförmige Dosimeter wobei nach Patent 1 240 593 die Metallhülle koni- abgeflacht und mit einer die Quantenstrahlung sehe öffnungen aufweist und die Wand der Metall- schwächenden Schicht5, z.B. aus Aluminium, und hülle auf dem Körper des Trägers zuzuordnenden einer weiteren mit Öffnungen versehenen, ebenfalls Seite dünner als auf der vom Körper abgewandten strahlenschwächenden Schicht 6, beispielsweise aus ^e'te 'st· 45 Kupfer, versehen.

The strength of the to 972, is a personal dosimeter for measuring both radiation-attenuating layers 5 and 6 , quantum radiation is known with a glass solid so that its permeability, based on permeßelement, that of a plastic mass and mean quantum radiation energies, about five at a distance of one, the radiation is 50 times the permeability of the metal layer 3 with the openings 4 absorbing their energy to different degrees. This ensures the spherical metal shell is enclosed; as the dosimeter shown in the drawing independent means to achieve an energy-independent depending on the direction of irradiation of the quanta, there is also a perforation of the metal - ie regardless of whether the quanta is recommended through filters. 55 have to go through the body or directly on the do-
