The devices have total ionizing dose (TID) capability of up to 300 Krad(Si), single event effect (SEE) immunity to 82 MeV, and are available in screened and commercial off- the-shelf (COTS) versions.
So a proton is made of three quarks whose masses add up to about 10 MeV, and a whole bunch of massless gluons, and somehow it still has 938 MeV as its mass.
