<p>PROBLEM TO BE SOLVED: To provide a disposable mask that can collect/adsorb aerosol type radioactive substance and gaseous radioactive substance.SOLUTION: A disposable mask 10A includes: a first fiber nonwoven fabric which is made of thermoplastic synthetic resin fiber; an electret second fiber nonwoven fabric that is made of thermoplastic synthetic resin fiber and that is superimposed on the outside of the first fiber nonwoven fabric; a nonmelting active carbon fiber sheet that is made of active carbon fiber for collecting aerosol type radioactive substance and gaseous radioactive substance contained in the outside air, that is superimposed on the outside of the second fiber nonwoven fabric, and that is loaded with amines for adsorbing these radioactive substances; and a third fiber nonwoven fabric that is made of thermoplastic synthetic resin fiber and that is superimposed on the outside of the active carbon fiber sheet. The outer periphery of the first to the third fiber nonwoven fabrics is deposited/fixed through an outside deposition part. The outer periphery of the active carbon fiber sheet that is interposed between the outer peripheries of the second and the third fiber nonwoven fabrics is fixed to the outer periphery of the first to the third fiber nonwoven fabrics through the outside deposition part.</p> |
