Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a radioactive substance filter which is capable of reducing disassembly work and reducing the volume of waste regarding problems in radioactive waste storage and radioactive waste processing.SOLUTION: A radioactive substance filter is comprised of only combustible materials including combustible filter media comprised of only a laminate of polypropylene melt blow unwoven fabric, a combustible frame comprised of veneer plywood and a combustible separator comprised of polyethylene or polypropylene coating paper. A pressure loss under a filter unit rating air capacity 50.0 m/min is 300 Pa or less and collection efficiency of 0.15 μm particles according to JISZ4812 is 99.97% or more.
