A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...
conclusions comprehensive protection programs with on-the-job training courses for staff members are strongly recommended, as well as, the provision of radiological shields and gonad shielding protocols in radiology departments to reduce the patient’s radiation dose during radiological examinations. materials and methods a retrospective, observational cross-sectional study on the application of...
There exists serious miscomprehension in the open literature about electromagnetic interference shielding effectiveness (EMI SE) as a critical index to evaluate performance, which is misleading graduates and newcomers embarking on field of materials. EMI SE defined sum three terms including reflection loss, absorption loss multiple classical Schelkunoff theory, while it decomposed into two name...
Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy ...
Complicated environmental problems inevitably arise when technology advances. One major environmental problem is the presence of electromagnetic radiation. Long-term exposure to electromagnetic radiation can damage people’s health in many ways. Therefore, this study proposes producing composite boards with electromagnetic shielding effectiveness and thermal insulation by utilizing the structure...
