One of the interesting items we have this week is a study by Greenpeace in which various organisms from the sea near Fukushima were sampled for radioactive isotopes. Let's take a closer look.
The data in the table provided (see the first item in Ana's feed for the link) show the amount of radiation (radioactive decay) by isotope type per kilogram of plant or animal tissue from various samples. On the higher end is a fish with 357 bq/kg of radiation and some seaweed with 190 bk/kg.
