Charged particles may be attenuated by losing energy to reactions with electrons in the barrier, while x-ray and gamma radiation are attenuated through ...

Performances of Kevlar and Polyethylene as radiation shielding

WebApr 12, 2024 · Wearing the EMI shielding technical clothing to block the extra electromagnetic radiation, has been approved as one of the efficient methods for EMI shielding, which is capable of attenuating electromagnetic radiation propagation efficiently via reflection, absorption, and multi-reflection inside the material. 8–10 Among them, … WebNine different types of polyethylene were irradiated in air and their melt indexes determined as a function of radiation dose. Equations were derived which relate the melt index to the dose. The initial slopes of the curves represented by these equations were found to be related to the initnal molecular weight and/or the initial crystallinity of the polyethylenes … earth day 2021 activities for kids
