Hi Reefers,
Randy, i hope you dont mind that im hijacking this category for a single question
So here we go:
Natural seawater contains about 3 µg/l of Uranium (this is way more compared to several other trace elements such as Selenium, Chromium, Iron, Manganese & co).
Since Uranium has only unstable isotopes this uranium content makes seawater radioactive. The radioactivity caused by the uranium is in the range of 0,04 Bq/l (Becquerel per litre). However, the real radioactivity of natural seawater is by orders of magnitude higher (~12 Bq/l), so there must be some other contributors besides Uranium.
Which element is the major contributor to the radioactivity of seawater?
A) Caesium
B) Strontium
C) Potassium
D) Carbon
Have fun!
all the best, Christoph
