PROBLEM TO BE SOLVED: To provide a reusability determination method of a dust collection filter for realizing operation cost reduction by reducing disposal cost of the dust collection filter by making full use of the dust collection filter without waste, and a dust collector utilizing the dust collection filter efficiently by performing reusability determination. SOLUTION: In this reusability determination method of the dust collection filter, a dose condition wherein a radiation of radioactive dust in the dust collection filter is low if a radiation dose from the radioactive dust collected by the dust collection filter is smaller than a boundary dose determined beforehand, and a pressure condition wherein a pressure loss caused by deposition of the radioactive dust in the dust collection filter is lower than a prescribed value if a space pressure on the downstream of the dust collection filter is higher than a boundary pressure determined beforehand, are examined respectively, and only when both the dose condition and the pressure condition are satisfied, the dust collection filter is determined to be reusable. In this dust collector, effective utilization of the dust collection filter is realized by the reusability determination method. COPYRIGHT: (C)2006,JPO&NCIPI
