Title: Disposable N95 Masks Pass Qualitative Fit-Test But Have Decreased Filtration Efficiency after Cobalt-60 Gamma Irradiation Document date: 2020_3_30
ID: kl9huu33_13
Snippet: The masks were inserted into a specialized air duct, and ambient particulate matter was flowed through the duct (through the filter), with a pressure differential of approximately 175 pascals at 0.4 m/s face velocity. 0.3, 0.5, and 1 µm particles were tested, and the filtering efficiency was measured using an optical particle counter (Aerotrak 9306, TSI Inc.)......
