One self luminous exit sign contains about 0.00074 PBq of tritium. The Fukushima stored water contains about 0.76 PBq of tritium(as of 2018), enough for about 1027 signs. I suspect there is far more tritium in the exit signs in Tokyo then there is in the Fukushima water. If you want to more than net out the radiation release from dumping this water, close one small coal plant. https://safecast.org/2018/06/part-1-radioactive-water-at-fukushima-daiichi-what-should-be-done/ https://safecast.org/2018/06/part-1-radioactive-water-at-fuk... https://www.everglow.us/pdf/tritium-exit-sign-fact-sheet-lan https://www.everglow.us/pdf/tritium-exit-sign-fact-sheet-lan...
