Marvel: Microwave Emission Immunity

Angelica Jones (Firestar)
Firestar is apparently immune to most of the damaging effects of the microwaves she emits, although she did undergo tests with Henry Pym to make sure. Unlike most mutant, however, her immunity to her own power was not complete; she was in danger of rendering herself sterile until a cure was discovered by Henry Pym in the form of a special suit. Pym claimed it would take about six months for the process to be complete and, over time, Firestar appeared to be functionally immune to microwave radiation.
