It's not that easy to control radiation, controlling it to the level of individual decays is not possible.

The closest you can get is bring it closer/further, or shield/unshield.

I'd rather use a local source in a Faraday cage, so that it's not possible for someone to influence the output at all.

A Faraday cage is not going to block this type of radiation.
