Back in the day when I was involved with high power YAG lasers, there was a similar radioactively doped trigger called a Krytron that operated the Q-switch and had to operate at nanosecond switching time. It even had a radioactive symbol on it.

These came from the States, and were subject to all sorts of import controls - and at the end of life had to be returned. Reason was that the main use was as the trigger for things that went seriously bang.
