Professor Hayakawa went to Koriyama City in Fukushima Prefecture and walked in Kaiseizan Park right near the City Hall. Compared to his walk in Edogawa-ku, Tokyo on the previous day, the radiation levels in Koriyama City is markedly higher (no surprise).
This time, the professor is armed only with his personal survey meter that only measures gamma ray. He seems to have a protective case on the survey meter, so I don't think he is laying down the survey meter "naked" on the grass or dirt. (He's been doing this for one year now in various locations, after all.)
He took the measurement of "black dust" at 4 locations:
3.533 microsieverts/hr
9.103 microsieverts/hr
7.291 microsieverts/hr
6.331 microsieverts/hr (in the City Hall parking lot)

This isn't a "game" get out of japan, if bad stuff happens you'll get to live, if you stay, I do not like gambling with innocent lives!!!!

@anon at 4:05PM, thanks for the map. Did you notice anything that look like "black dust"? What was the location that measured 1 microsievert/hour?
No black dust seemingly. A regular sandy depression on concrete is marked with 1 mcSv/h. (I did not make the map and measurements.)
@anon at 7:32PM, that's what Hayakawa says.
I live directly next to the park (which is called KaiseiZAN not Kaiseiyama) and I am going to walk it tomorrow and check these readings. I have the same dosimeter that he showed.
@anon at 2:34AM, thanks for the correction. Please post your result here, or link to the everytrail if you do that on that platform.
I am anon-2:34am
I just did this and got similar results though slightly lower. I took photos trying to match his as best as possible.
I have to call BS on the 9 reading because he had to stray out of the park and behind a building and take a reading right above a water drainage gutter to get that reading. I only got a 3 at that location, which was one of the higher ones. My argument is that he must have left the park, which had much lower readings and walked around constantly taking readings until he found a higher reading. The marker on the map shows him being in front of the building, but the drain in the image is located behind it and the parking lot near orange apartment building.
To be fair we were using an air counter. He shows a similar model in a plastic bag in some images. The ground readings were higher than the readings at chest high.
Thanks, Ryan. I think Hayakawa did stray out of the park. He's been actively looking for high radiation "black stuff" everywhere he goes, and been asking his followers for measurements in their cities with their survey meters.
I'll tell him to be more precise about the location...
(If you can tell us more about how the life is in Koriyama right now, I'd much appreciate.)
I understand the scientific interest in this but unless you're actually working to bring the situation under control you need to get as far away from those reactors as possible... Don't be taking turns checking radiation levels when you know it's already contaminated.
