CUORE—the Cryogenic Underground Observatory for Rare Events—is an experiment searching for the neutrinoless double-beta (0νββ) decay of 130Te with an array of 988 TeO2 crystals operated as bolometers at ~10 mK in a large dilution refrigerator. To achieve our target 130Te 0νββ decay half-life sensitivity of 9×1025 y with 5 y of live time, we seek to minimize backgrounds. To avoid the recontamination of the detector via exposure to radon gas during its installation in the cryostat, we perform all operations inside a dedicated cleanroom environment with a controlled ultralow-radon atmosphere. In this talk, I discuss the design and performance of the CUORE Radon Abatement System and cleanroom, as well as real time radon level monitoring.
