  • Publication number: 20250138207
    Abstract: Disclosed is a technology related to a compact radiation detection apparatus used to measure airborne radiation. The compact radiation detection apparatus includes a cylindrical filter, a detector assembly coupled to one end of the cylindrical filter, and a pump assembly coupled to the other end of the cylindrical filter. Negative pressure is formed in an inner space in the cylindrical filter by a vacuum pump, and accordingly, aerosol is continuously collected on the surface of the cylindrical filter. A detector located in the inner space in the cylindrical filter detects radiation emitted from the collected aerosol.

  • Publication number: 20250125063
    Abstract: Disclosed is an apparatus for reducing floating radioactive material in a containment building capable of reducing radioactive material in the event of a major accident in a containment building such as a nuclear power plant. A radioactive material reduction unit configured to reduce radioactive material in the air is provided upstream of a flow induction unit configured to induce an air flow through catalytic reaction with hydrogen in the air in the event of a major accident. The flow induction unit may have a replaceable modular form. The radioactive material reduction unit may include an adsorber module configured to remove gaseous radioactive material, such as iodine or an iodine compound. The adsorber module may have a replaceable modular form. In addition, the radioactive material reduction unit may further include an aerosol filter fixed to an inlet to remove particulate radioactive material.
