Bq = Becquerel. A measure of radiation.

First from Freeper:

1. "Radiation Levels of Sunken Russian Nuclear Submarine 100,000 Times Higher Than Normal"

"Radiation levels in the water around a sunken Soviet-era nuclear submarine are some 100,000 times higher than normal, scientists have warned, raising fears that the K-278 Komsomolets may still pose a threat 30 years after it sunk"

Mike class Soviet era submarine K-278 Komsomolets on it's first operational patrol foundered and sank. 

Additionally from the Barents Observer and the article by Thomas Nilsen:

2. "'Komsomolets' leaks radioactivity"

"One sample taken from an open ventilation hole of the wreaked Soviet nuclear powered submarine shows levels of about 800 Becquerel [Bq] per liter." [one liter equals about one-quarter gallon U.S.]

Undersea ROV [remotely operated vehicle] at the site of the sinking taking multiple water samples to measure the radiation sample at the boat itself.

"The highest level researchers found was around 800 Bq per litre. Typical levels for seawater in the Norwegian Sea today are around 0.001 Bq per litre. In other words; the samples shows radioactivity 800,000 times higher than normal"

A radioactive level of 100 becquerel/liter is not considered to be dangerous!

"'Komsomolets' (K-278) rests at the seafloor at a depth of 1,680 meters, where there are very little marine life, so the risks of having the radioactivity into the food chain is very little."

I guess we are OK then?
