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.
In September 2001, letters containing anthrax spores were mailed to several news media offices and two U.S. Senators, killing five people and infecting 17 others.

The PA requirement observed in animal-model experiments demonstrates a common paradigm for bacterial toxins, called the A / B paradigm. The A component is enzymatically active, and the B component is the cell binding component. Anthrax toxin is of the form A 2 B, where the two enzymes, EF and LF, are the A components and PA is the B component ...
The Supreme Court made it easier for employees to seek religious accommodations in the case of an evangelical Christian mail carrier who asked to be off Sundays.
The pXO1 plasmid (182 kb) contains the genes that encode for the anthrax toxin components: pag (protective antigen, PA), lef (lethal factor, LF), and cya (edema factor, EF). These factors are contained within a 44.8-kb pathogenicity island (PAI). The lethal toxin is a combination of PA with LF and the edema toxin is a combination of PA with EF.
