1. A lamellar arrangement for shielding radiation acting on a fluid which flows through an interior of a device, comprising:
two or more lamellae aligned substantially parallel to one another and respectively defining an intermediate space between them;
wherein at least one subset of the lamellae is respectively subdivided into at least three lamella sections comprising a first lamella section, a second lamella section next to the first lamella section and a third lamella section next to the second lamella section;
wherein the first lamella section and the second lamella section enclose a first angle between them, and the second lamella section and the third lamella section enclose a second angle between them;
wherein the first angle has a magnitude in a range of from 20° to 45° and the second angle has a magnitude in a range of from 20° to 45°;
wherein a reflectance of one or both surfaces of the first lamella section is greater than a reflectance of one or both surfaces of the second and third lamella sections and, if present, of further lamella sections
wherein the reflectance of one or both surfaces of the first lamella section is 30% or more, and the one or both surface of the first lamella section are structured by a surface treatment, as a result of which a full width at half maximum of angles of a scattered radiation is at least 10°, or at least 35° or at least 50°.
