The Pulsar promotional video recently put on youtube (too lazy to provide a convanient link as I usually do
) also mentions the LASER BEAMS used to cut the ceramic carrier substrate. Yes, Laser was a big thing at that time (especially in movies...).

Hysteria, to some extent. Unless broken, they are absolutely harmless. And if broken, still harmless until ingested or breathed in. BUT: if you spread tritium tubes to the public in huge numbers, you can never guarantee that not some of them get broken and ingested or inhaled. I guess that's why they disappeared.
