For the first time strontium 89 and 90 have been found on the seabed near the Fukushima Daiichi nuclear plant.

Tokyo Electric Power Company tested the soil at the bottom of the Pacific Ocean, on 02 and 03 June 2011, at locations 20 kilometers (12 miles) from the nuke plant.

While this is the first time strontium has been found in the seabed, it is not the first time it’s been found in the water.
