Claims

[Scope of utility model registration request]

A filter cartridge storage section that stores a plurality of filter cartridges made of radioactive gas collection material and automatically brings the filter cartridges one by one into a transportable state, and piping through which sample gas containing radioactive gas is guided. The filter cartridge is connected to the piping line and is airtightly bonded to the piping path, and has a collection part that collects the radioactive gas, and an arm that can grip the filter cartridge, and rotates the filter cartridge from the storage part. a filter cartridge transport unit that transports cartridges one by one to the collection unit; a measurement unit that measures the radioactive gas; and a filter cartridge that is transported by the filter cartridge transport unit and collects the radioactive gas. a filter cartridge slide mechanism that slides and sets the cartridge in the measurement section, and the filter cartridge storage section, the collection section, and the filter cartridge are moved along the circumferential path of the rotational movement of the filter cartridge transport section. A radiation measuring device arranged in the order of a filter slide mechanism includes: a filter cartridge mounting mechanism that is movably provided on a circumferential path of the filter cartridge transport section between the collection section and the measurement section; Control means for controlling the cartridge mounting mechanism to alternately replace the filter cartridge in the collection section and the filter cartridge in the measurement section at a predetermined time to repeat collection and measurement until a required detection sensitivity is reached. A radiation measuring device characterized by comprising:
