A SAMPLING SYSTEM FOR AIRBORNE RADIOACTIVITY USING AIRCRAFT

摘要

PURPOSE: A device for collecting atmospheric granules and radioactive materials efficiently in an aircraft is provided to recognize a location of a missing radioactive material easily, and to apply radioactive air exploration technology in an emergency accident. CONSTITUTION: A device for collecting atmospheric granules and radioactive materials efficiently includes a suction nozzle(1), a filter paper holder(2), a metal net(3), an air filter(4), a HEPA filter(5), an active carbon filter(6), an inhalation flux measuring unit(7), and an air outlet(8). The device has the same shape with a shape of a rocket launching tube. Each filter is comprised of a cartridge. The suction nozzle is installed at an inlet. The filter paper holder is installed at a rear side of the suction nozzle. The filter paper holder supports the filter paper. The metal net supports the filter paper. The air filter is installed at the rear side of the metal net. The HEPA filter is installed at the rear side of the air filter.
