    • A respiratory filtration device adapted for use with gas masks or respirators for filtering tritiated water vapor from a gas is provided. The inventive device employs novel filter media, which has a fluting pattern in which a series of generally longitudinal ridges or flutes extend along paths having alternating lateral divergences from a generally upstanding axis (e.g., a pattern of substantially parallel wavy flutes) instead of traditional fluted paper filter media having straight parallel fluting (e.g., E Flute paper). The use of this novel filter media favorably impacts upon the tritium capture efficiency of these respiratory filtration devices.
    • 提供了一种适用于与防毒面具或呼吸器一起用于从气体中过滤氚化水蒸气的呼吸过滤装置。 本发明的装置采用新颖的过滤介质,其具有凹槽花纹,其中一系列大致纵向的脊或凹槽沿着路径延伸,所述路径具有与大致竖直的轴线(例如,基本上平行的波浪形凹槽的图案)交替的横向发散,而不是传统的凹槽 具有笔直平行凹槽的纸张过滤介质(例如E长笛纸)。 这种新型过滤介质的使用有利地影响这些呼吸过滤装置的氚捕获效率。
