摘要： Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

摘要： An ionizing radiation shielding panel comprising a core layer, a first layer on a first side of the core layer and a second layer on a second side of the core layer, opposite to the first side. The core layer comprises radiation attenuation material which may be particles of barite. The first and second layers each comprise a permeable reinforcement structure and each of the first, second and core layers are permeated with a binder. In the construction of the panel, the binder is infected into a mould containing the other constituents of the panel. The ionizing radiation shielding panel can be used in the housing of an x-ray inspection apparatus.

摘要： The present invention relates to rigid structures and composite materials thereof for providing radiation attenuation/shielding. Some embodiments pertain to a radiation shielding apparatus including: a plurality of positionable radiation-shielding stacks of tiles. The stacks are subsequently and adjacently arranged in a contiguous configuration. A tile positioning mechanism allows movement of tiles within a stack between a stacked (retracted) position and an extended position. In the extended position, the tiles of each of the plurality of radiation shielding stacks at least partially overlap tiles of subsequent and adjacent tile stack at corresponding opposing side-margins thereof.

摘要： The present invention discloses a method for manufacturing a lead-free radiation shielding sheet. The method for manufacturing a lead-free radiation shielding sheet according to the present invention comprises a film laminating step of forming a multi-layered radiation shielding film on one side of a base material by repeating a process of applying to laminate, drying, and integrating a radiation shielding material containing a radiation shielding powder and a binder for forming a film to be mixed with each other on one side of the base material for forming a radiation shielding sheet. According to the present invention, since heavy lead which is harmful to the human body and the environment is not used, side effects such as disease or environmental pollution caused by lead do not occur, the light weight of the radiation shielding sheet is enabled, and protective clothing with excellent wearing sensation can be manufactured, and since flexibility can be improved compared to lead rubber sheets, handling and storage are convenient. In addition, the lead-free radiation shielding sheet manufactured by the present invention can be applied as clothes of various designs and radiation protection means for various uses due to flexibility and ease of operation.
