United States Postal Service Irradiated mail (original) (raw)
Irradiated mail is mail that has been deliberately exposed to radiation, typically in an effort to disinfect it. The most notable instance of mail irradiation in the US occurred in response to the 2001 anthrax attacks; the level of radiation chosen to kill anthrax spores was so high that it often changed the physical appearance of the mail. The United States Postal Service began to irradiate mail in November 2001, in response to the discovery of large-scale contamination at several of its facilities that handled the letters that were sent in the attacks.

| dbo:abstract | Le courrier irradié est du courrier qui a été délibérément exposé aux radiations, dans un effort de désinfection. La pratique la plus remarquée de cette irradiation se déroula en réponse à l'épisode des enveloppes contaminées au bacille du charbon ; le niveau de radiation choisi pour tuer les spores d'anthrax était si élevé qu'il changea souvent l'apparence physique du courrier, dans certains cas de manière spectaculaire. Les services postaux aux États-Unis commencèrent l'irradiation du courrier en novembre 2001, en réponse à la découverte de contamination à grande échelle de plusieurs de ses installations de traitement de courrier qui étaient envoyés durant les attaques. Une installation à utilisa un accélérateur linéaire de la pour irradier le courrier. Peu d'installations ont prévu d'utiliser les sources de cobalt 60, bien qu'il ne soit pas clair de savoir si cela a déjà été fait ou pas.

The most notable instance of mail irradiation in the US occurred in response to the 2001 anthrax attacks; the level of radiation chosen to kill anthrax spores was so high that it often changed the physical appearance of the mail. The United States Postal Service began to irradiate mail in November 2001, in response to the discovery of large-scale contamination at several of its facilities that handled the letters that were sent in the attacks. A facility in Bridgeport, New Jersey, operated by Sterigenics International, uses a Rhodotron continuous wave electron beam accelerator built by IBA Industrial, to irradiate the mail. A few facilities were planning to use cobalt-60 sources, though it is unclear whether this was ever done. (en) |
