Tritium keychain inducing current in a coil...I'm confused

    I did not in fact know you could buy Tritium keychains. I was under the impression it was too hot to handle.

    In this video on Youtube. At one minute. The guy passes his copper coil over the the Tritium keychain. The LED lights up. I know how electrical induction works, but this does have me confused. I didn't know you could do this with radioactive samples.

    I imagine that keychain is a magnet and there's a reed switch and a button cell hidden under that black tape.

    I think the keychain really is tritium, because other people have videos doing different things with them. It's a small amount of some tritium compound, in some kind of casing/shielding that fluoresces. I don't know, in theory passing charged particles through the hoop of the coil should induce a current, but I'm confused as to what's going on here.
