摘要： Provided are a filtration material for filtered venting and a filtered venting device that are more effective in adsorbing radioactive iodine than in the conventional art and are useful for addressing severe accidents. The filtration material for filtered venting comprises granulated zeolite L, wherein at least a portion of the ion exchange sites of the zeolite L are substituted with silver. Of the ion exchange sites, a constitution ratio (a/b) of ion exchange sites (a) substituted with silver to ion exchange sites (b) not substituted with silver is 25/75-55/45. The zeolite L has a silver content of 7-12 wt % on a dry weight basis.

摘要： Provided is a new heat source device that utilizes the catalytic reaction heat as a heat source for industries. The heat source device 100 utilizing the catalytic reaction heat of silver zeolite 1 includes an accommodation container 10 for accommodating the silver zeolite 1 while ensuring air permeability, wherein the accommodation container 10 is configured to be ventilated with a mixed gas G containing hydrogen, steam, and air. The mixed gas has a hydrogen concentration of 1 to 20% by volume, a steam concentration of 1 to 95% by volume, an air concentration of 1 to 95% by volume, and a temperature of 100° C. or higher.
