Abstract

Shielding apparatus has a number of shielding units 1. Each shielding unit (1) includes two planar sheet members (2, 3). The sheet members (2, 3) are arranged such that a planar surface of one of the sheet members (2) covers a planar surface of the other of the sheet members (3). The planar surfaces of the sheet members (2, 3) are of substantially the same dimensions and the sheet members are mutually offset (6) from each other so that a portion of the planar surface of each sheet member (2) is not covered by the other sheet member (3).
