PROBLEM TO BE SOLVED: To detect a radiation dose in radioactive dust included in sampling air, and simultaneously to detect a radiation dose in a gaseous radioactive material included in the sampling air, concerning a radioactive dust monitor. SOLUTION: In a sampling vessel 1, a filter paper 4 for capturing dust in the sampling air by passage of the sampling air, and a gas adsorbent 8 for adsorbing radioactive gas in the sampling air by passage of the sampling air are provided, and a radiation detector 2 for detecting each radiation dose in the dust and the radioactive gas captured and adsorbed respectively is also provided.
