When it was fresh, it was about 1740Sv/hr ish at 6 inches. That...that...that is very intense.
After the amount it has decayed, it is likely at about 2 Sv/hr....that is still very intense. Very easy to obtain a lethal dose in either case.
About 2 Sv rapidly is when we expect a relatively high chance of mortality without treatment, and about 4 Sv is where we expect relatively high mortality even with treatment. 8 Sv is about certain you will die no mater what.
When it was fresh, one could expect a 2 Sv dose, in about 4 seconds, and an 8 Sv absolutely lethal dose in 8. Drop and run indeed, but even then, likely to late.
The decayed source would take an hour or 4 to give you the same range of doses. So enough time to read and run.
