StemRad

It is meant to be worn by first responders (fire fighters, paramedics, police and the military), that would be exposed to radiation in the event of a nuclear emergency.

[11][12][13] AstroRad is personal protective equipment for astronauts to be worn beyond low Earth orbit which was co-developed by StemRad and Lockheed Martin.

Four female astronauts wore the AstroRad vest in microgravity for variable durations during routine activities, providing feedback on ergonomics, range of motion, comfort and general user experience.

[24] By comparing the dosimetry data from Helga and Zohar, the effectiveness of the AstoRad vest in shielding astronauts from radiation in deep space will be experimentally quantified.

The StemRad MD is a protective system designed for interventional radiologists and other physicians who perform medical imaging using ionizing radiation, most notably fluoroscopy.

It is positioned at an angle so that it blocks most of the radiation coming from underneath and allows the physician to wear unshielded prescription glasses while performing procedures.
