Anybody know if it's still possible to get thorium mantles of the sort

Yes. The cheap Chinese mantles contain thorium, expect 500-600 Becquerel.

Anchor and Egret are mantle brands that are radioactive, Luxor and Petromax
aren't.

Just take you Geiger counter into the shop!

Thanks for the info. But using the Geiger counter to select a mantle
might not be too clever. ;-)
