Uranium glass occupies an little-known niche in the collectibles world, whose members appreciate its soft colour and distinctive glow, which comes from the uranium added as the glass was created. The glass is slightly radioactive, enough to register on Geiger counters. But the levels are about the same as electrical appliances like microwave ovens emit, so they represent no threat to health.

The head of Japan's atomic watchdog has said that the new safety regime meant a repeat of the Fukushima disaster would not happen, but protesters outside the Sendai plant are not convinced.

Survivors of the Hiroshima and Nagasaki attacks, 70 years ago this month figure among a majority of Japanese opposing a plan to reboot reactors taken offline after the Fukushima nuclear disaster.
