  • Patent number: 10342232
    Abstract: A binder, and related processes, has been developed for biological agent defeat formulations. This highly iodinated binder is based on the polymer polyethylene tetraiodoterephthalamide. The materials have been formulated with metal fuel particles, such as aluminum, and various oxidizers, such as metal oxides. The binder-thermite composites may be actuated to initiate oxidation, therein generating heat. Upon thermal decomposition of these materials, iodine, a biocide, is released allowing for sterilization of biological agents.

  • Publication number: 20140166909
    Abstract: In the present invention, there is provided, as a shielding material for beta rays or gamma rays emitted from an earth surface surrounding a nuclear power plant after an accident, a rubber sheet wherein a synthetic rubber or natural rubber, each containing no vulcanizing agent is compounded with a large amount of sand iron or barite. By placing this shielding material on a radiation-contaminated earth surface, or by reversing the position of the soil of earth surface of higher radiation dose and the position of the soil beneath the earth surface, of lower radiation dose, in such a way that the above-mentioned shielding material is placed between the new upper-position soil of lower radiation dose and the new lower-position soil of higher radiation dose, the dose of radiation emitted from the earth surface can be reduced.

  • Publication number: 20140158918
    Abstract: An ionizing radiation barrier includes a binder selected from thermoplastics, silicone elastomers, plastisols and organisols; and high density particles dispersed throughout said binder. The particles are preferably homogeneously dispersed and the radiation barrier is preferably devoid of air bubble and pin holes. The high density particles are radio-opaque so as to provide for radiation attenuation. A method of protecting a body from ionizing radiation includes positioning such an ionizing radiation barrier between an ionizing radiation source and a body to be protected. A method for producing an ionizing radiation barrier includes the steps of: homogeneously dispersing high density particles in a binder to create a loaded binder; deaerating the loaded binder to remove air bubbles; forming a desired structure from the loaded binder; and setting the loaded binder.

  • Patent number: 8728349
    Abstract: An overall lead-free X-ray shielding rubber compound material. The overall lead-free X-ray shielding rubber compound material uses rare earth mixture to replace lead, simultaneously adds metal tin and compounds thereof, metal tungsten and compounds thereof and bismuth and compounds thereof as shielding main materials and is further compounded with rubber to prepare the compound material which can realize the overall shielding and the complete lead-free property within the energy range of 40-170 kVp. When rare earth and bismuth materials are used, the way of combined use of two metal element inorganic compounds and unsaturated organic complexes is adopted, and the in-situ reaction and the compounding with a polymer matrix are carried out, thereby leading the shielding element disperse phase to form nano-micro-level dispersed particles.
