The RAD Emergency Bra is a specialty Emergency Bra: a brasserie convertible into face masks with a radiation sensor incorporated into the body of the bra. In the event of an emergency, look for a change of color in the upper opening of the sensor’s pocket located under the front clasps of the brassiere. If the top opening (sensor strip) has developed a color darker than that of the lower opening (service life strip), convert the Emergency Bra into face masks and apply the mask while proceeding with the evacuation. For a quick estimate of the dose (in RAD units), remove the sensor and match the sensor’s color with side calibration bars of 25, 50, 100, 200, 400, and 1,000 RADs.

With sensor technology rapidly developing, different sensors, such as biological, chemical, and so forth, will be incorporated into the Emergency Bra in the future. The purpose of these sensors is to detect the presence of harmful airborne particles that require the use of respiratory protective masks.

The bra can still be got for $50, but is sadly not available in any letter above D-cup tits!

Circa 2009, a Northwestern University journalism student produced an actually-nice report on the bra-phenom – funny:
