germicidal fixture, CE-36-
2, with two germicidal (254 nm) slim line (GML005) lamps. The
dimension of the CE fixture is 94 18 19 cm. The UV lamp fixture
was mounted horizontally by adjustable, tripod style legs. The UV-C
lamp apparatus and exposure area was enclosed with sidings lined
with aluminum foil to increase the containment of the UV light. The
surface on which the samples were placed was covered with bench
coat (Versi-Dry Lab Soakers; Fisher Scientific, Pittsburgh, PA). The
intensity of the UV-C light was measured using a Newport power
meter model 1928-C (Newport Corporation, Irvine, CA). The UV-C
light was allowed to warm up at least 30 min prior to use.
