For some context a Becquerel (Bq) is a single decay per second (note the graph shows mBq/l). One gram has an activity of ~3 TBq.
Though 137-Cs has a half-life of ~30yrs it has a biological half-life of ~70 days. (30 if you are treated with Prussian Blue). It fairly uniformly distributes through the body, though it has higher concentrations in soft tissues, which does pose greater damage (see Sievert).
That being said, these are such low quantities you'd die of alcohol many times over before increasing your chance of cancer by 1% over the course of your lifetime.
From Wiki they gave some dogs a dose of 140 MBq/kg and they all died in 33 days. When they gave some other dogs half (70MBq/kg) dosage all the dogs survived.
