Addition of Lead (Pb)-Nitrate Filler on Polymer Composite Aprons for X-Ray Radiation Shielding
نویسندگان
چکیده
Radiation shield ing aprons are needed by radiation workers to minimize exposure the body. The apron s at present use fabric-coated lead plates which heavy and rigid materials therefore not comfortable use. Polymer from cassava starch glycerin with addition of Pb- nitrate filler 0 %, 2 4 6 % have been synthesized. Mixtures for synthesizing polymer composites were heated using a magnetic stirrer speed 800 rpm 160 °C 25 minutes. Then, dried in an oven 24 hours 70 °C. effectiveness was determined calculating attenuation coefficient ( μ ), half-value layer (HVL), absorption. mechanical properties characterized testing their tensile strengths A&D MCT-2150 universal tester. result shows that optimal as much produced 1248 cm ‑1 , HVL 0.54 cm, absorption while aprons’ strength obtained 28.244 MPa. T he Pb-nitrate proportionally improves quality used shields. More detailed research is still obtain best apron.

Modeling of Dynamic Behavior of Carbon Fiber-Reinforced Polymer (CFRP) Composite under X-ray Radiation
Carbon fiber-reinforced polymer (CFRP) composites have been increasingly used in spacecraft applications. Spacecraft may encounter highenergy-density X-ray radiation in outer space that can cause severe damage. To protect spacecraft from such unexpected damage, it is essential to predict the dynamic behavior of CFRP composites under X-ray radiation. In this study, we developed an in-house three...
متن کاملDosimetry of Occupational Radiation around Panoramic X-ray Apparatus
Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
متن کاملNano composite PEBAX® membranes: Effect of zeolite X filler on CO2 permeation
A PEBAX-nano zeolite X mixed matrix membrane was fabricated and operationally characterized using single gas (CO2) permeation. X-ray diffraction (XRD) analysis was used to study the arrangement of polymer chains of mixed matrix membrane. The membranes were characterized by scanning electron microscopy (SEM) to study cross-sectional morphology. The single gas permeability were carried...
متن کاملEmerging technology for shielding of electromagnetic radiation using composite materials
This study indicated that multi-walled carbon nanotubes (MWCNTs)-epoxy composites can be used as effective lightweight shielding materials. The measurement results showed that highest EMI SE of 23.4 dB at 8 GHz was obtained for nanocomposite with 1 wt% MWCNTs. Dielectric properties and electrical conductivity values were supplemented by microscopic studies.
