A few examples of Caesium contamination that I have come across:
Radioactive cesium levels within 60km of Fukushima 1. From a US/Japanese aerial survey. Note that after Chernobyl, the Soviets evacuated people from areas over 550 Bq/m2. The original US govt map was here
Land-sea comparison: Organ dose to infants from ministry of education, March 25 Note this is a SPEEDI model based on known weather data and unknown total radiation release from the plant. The proportions of land/sea contamination are probably valid, the numbers may not be.
Plants with cesium levels over allowed limits, up to 350km from the Fukushima 1 This is by no means a complete list
