Radiation shield and methods for manufacturing a radiation shield are provided herein, the method includes identifying a substrate for the radiation shield; identifying at least one material for cold spraying on the substrate; applying by cold spray a coating of the at least one material on the substrate thereby obtaining a radiation shield. The radiation shield is lighter, thinner, and more efficient compared to conventional radiation shields.

A remote control protector for anti-light interference includes a body and a shelter. The body includes a housing space, a first surface, and a second surface. The housing space is for disposing a remote control. The first surface includes a first opening communicating with the housing space. The second surface includes a second opening communicating with the housing space and the second opening is adapted to expose a transceiver of the remote control. The shelter extends from the second surface of the body along an axial direction of the body, surrounds the second surface, and has an outlet opening communicating with the second opening of the second surface.

Systems, devices, and methods are described for providing, among other things, an intra-oral x-ray imaging system configured to reduce patient exposure to x-rays, reduce amount of scatter, transmission, or re-radiation during imaging, or improve x-ray image quality. In an embodiment, an intra-oral x-ray imaging system includes an intra-oral x-ray sensor configured to communicate intra-oral x-ray sensor position information or intra-oral x-ray sensor orientation information to a remote x-ray source.

The conventional radiation shielding materials are made using lead, barite and hematite ore which are either toxic, costly and are non-replinshable possessing limited functionality. In view of above, we develop a novel process for making advanced non-toxic Red Mud based functional radiation shielding materials utilizing appropriate novel matrixes like Advanced geopolymer, geopolymeric-polymeric matrix, putty, cement and phosphatic based matrix and are also compatible with conventional matrixes. The appropriate physico-chemical consolidation and or densification of red mud using advanced or conventional matrix helps in obtaining functional radiation shielding material by simultaneous and synergistic chemical reactions among various mineralogical and chemical compounds of red mud with complementary various chemical compounds present in citrus fruit peel waste especially citric acid to form nano gel material to obtain the fine tailored shielding powder. The developed material has broad application spectrum from diagnostic radiation installations like diagnostic X-ray to CT scanner room.
