Anthrax Detected At 2 Pentagon Mailrooms

WASHINGTON - Investigators are trying to learn why sensors at two military mail facilities in the Washington area detected signs of anthrax on two pieces of mail.

They are not sure whether the discoveries are signs of an attack.

The two pieces of mail, the origins of which were not provided, had been irradiated, so officials believed any anthrax in them was inert when they triggered alarms at the two mail facilities on Monday.

Additional tests and other sensors at the two facilities, one of them at the Pentagon and the other nearby, found no presence of the bacteria, which can be used as a biological weapon. There were no initial reports of illness.

The Pentagon's mail delivery site, which is separate from the main Pentagon building, was evacuated and shut down Monday after sensors triggered an alarm around 10:30 a.m., spokesman Glenn Flood said. It was expected to remain closed until at least Tuesday while the investigation continued.

Sorry about that. I just found out about it.

Sounds like a false alarm to me.

How does one detect irradiated biologicals?

Usually isn't there some biological reaction being monitored by the testers for confirmation?

If you're looking for Bacillus anthracis spores, you're not going to have ongoing metabolic reactions. Some of the sensors I've seen look for surface biomarkers on cells or spores through mass spec or the like. Others I've seen depend on cell lysis or spore breaking to detect nucleic acids. Neither approach requires live cells, necessarily.

I think that the detectors work by identifying proteins on the exterior of the cell or virus. Even dead, irradiated specimens have those proteins.

Apparently not. This is all the article had to say about that issue: "Pentagon spokeswoman Lt. Cmdr. Jane Campbell said mail at both facilities had been irradiated before arriving at either one. The radiation treatment should kill any anthrax bacteria, but sensors would still be able to detect it."
