Guaranteed to operate in ionizing radiation of 10^12 rad/s. Yikes, that's like 10 billion sieverts/s. Since a dose of something like 10+ sieverts is fatal I'm guessing a human would be turned to a puddle of goo around that much radiation.
Interestingly, in this radiation field, every kilogram of mammalian tissue absorbs 10 GW. If this blasts lasts for more than a few nanoseconds, your puddle of goo would be a good guess.
A nuclear bomb emits a fast flash of radiation over about 50 nanoseconds. Even if the total dose is small, it arrives fast enough to spuriously turn on transistors.
