IMPORTANT NOTICE ON WIPE TESTING
This package was handled and stored in an environment which might contain inactive phosphorescent pigment.
Wipe tests might show high counting rates in LSC caused by luminescent effect.
To test for luminescent effect please compare count rate after 1 hour and after 5 hours in complete darkness, a strong decrease of count rate should be obtained.
For a reliable determination of H-3 / C-14 surface contamination, the counting vials have to be stored for at least 30 hours in complete darkness.
