Kanagawa prefectural institute of public health published the data of radiation contained in air, tap water, fall out in 2011.
The monitoring post is located in Chigasaki, 275 km away from Fukushima.(Further than Tokyo)
According to their report, on 3/22/2011 (Rain), 9500 Bq/m2 of Iodine 131 fell off only within a day.
Also, significant sum of Tellurium 132 fell off from 3/16/2011. (I personally tool a day off this day.) The highest reading was 4000Bq/m2 on 3/22/2011 as well.
Tellurium 132 is produced when fuel clad is damaged by meltdown etc. Half life time is 3.3 days, turns to be Iodine 132.
Additionally, the hot particles in airborne dust were over scale on 3/16/2011. (I was staying at home this day.)
The data indicates 78,000 mBq/m3 of Te-132 but because the radiation concentration was too high, this is only the provisional value.
3/16/2011 was a sunny day but it was very windy.
