Abstract:

Passive diffusion badges are being tested as a long-term, low-level method of analyte-specific air analysis onboard U.S. Navy USN nuclear submarines. Passive badge monitors for monoethanolamine MEA detection were tested. Long-term sampling efficiency was evaluated for a 28-day period by comparing the response of the passive badge to an active tube sampling method. Simultaneous exposure of badges and tubes at concentration levels 100 and 20 of the USN 90-day submarine-specific limits was performed. High-level and low-level concentrations were tested to examine the response range of the badge. Badge results were stable and reproducible at 100 of the USN 90-day limit 0.50 ppm and were on average 25 lower than active sampling tube results. At the 20 level 0.10 ppm, the badge results were typically 14 lower than the tube results.
