6. I couldn't find data for that river
But typical river discharge rates appear to be a few hundred cubic meters per second for large rivers. Let's say that's 100 m^3/s here. There are 1000 l (and therefore about 1000 kg) per m^3, so that would be 100,000 kg/s.

50 x 10^9 Bq/day x (1 day/24 hr) x (1 hr/3600 s) x (1 s/100,000 kg) = 5.8 Bq/kg

I don't know how well-mixed the Cs would be; there may be higher or lower concentrations at the surface.

What is worse, having radioactive Cs wash out to sea via rivers or having it remain on land?
