The incident took place at Jåttå in Stavanger, at a military base that houses both NATO's training center and the Norwegian Defense Joint Operative Headquarters. The envelope, sent from the USA, was addressed to American representatives.
"The police have been called in and they took the powder, which is now sent for analysis," press spokesman Erling Kristiansen at DJOH told newspaper VG.
The woman, a civilian employee, is being treated as a precaution as the Defense cannot rule out the possibility of anthrax bacteria being sent.
The woman was in physical contact with the powder and was treated according to routine procedure, examined by health personnel and given antibiotics.
