Cs-137 deposition map of a hypothetical accidents at the NPP Rovno (4th of Dec 1995, 7:27 pm). Units in kBq/m2.

According to the accident management strategies after the Chernobyl accident a level of 1480 kBq/m2 leads to a relocation of the population. A level of 185 kBq/m2 makes long-term measures for dose reduction (e.g., making available non-contaminated foodstuffs) necessary.
