Query: Leakage Tests for Am-241 Solid Sources Used for Liquid Xenon Detector
  Monitoring   Experimental tests are described to check solid Am-241 radioactive sources
used to monitor operation of liquid xenon detectors. In particular, radioactive
leakage was tested in extreme temperature conditions following immersion in
liquid nitrogen for different time periods. No radioactivity loss was detected
from the sources considered. The paper describes the source characteristics,
test methods and results obtained.
