摘要

Foldable protective screen for electromagnetic radiation has metal or wooden mobile rack (1) having 3-4 parts and hinges (3). The entire surface of the rack including gaps (4) is covered with a shielding fabric (2). The material of different absorbability can be used either on inner side or outer side. The fabric can be changed using push buttons (5) depending on the material and shape of the rack. The absorption is in the range of 10 dB = 90 percent to 40 dB = 99.99 percent. The rack has a height of 160 - 180 cm, a width of 30 - 50 cm and a depth of 2 - 4 cm.
