On Oct. 22nd and 23rd, Tokyo Institute of Technology had the yearly festival, and I attended a few lectures on the Fukushima Daiichi disaster and radioactivity and also a program to measure radioactivity. This is my first time to visit this campus.
I got off at Oookayama station and walked into the campus to the green district.
This was on 23rd. We did some experiments.
These are samples we were going to measure their radioactivity.
Hakarukun is the name of this device. It means Mr. Measuring. I placed it on a Chinese ceramic bowl. The colors and glaze emit radioactive material. After a minute or so, it did go up, but very little.
A student is measuring a tiny piece of uranium.
A man in our group suspected this corner. So, I placed my hakarukun there.
0.204 micro sievelt. It was the highest I measured that day.
I wanted the device, but I heard it costs over 1000 or 2000 dollars.
This was toward the end of the day, but the campus was full of people and foods and entertaiment everywhere.
He had a cafe across our lecture hall. I wasn't sure what they served because it was dark inside.
Kaneko Takeshi san (金古 岳史さん）and me. He took my application and helped me to do my experiment. They are all very helpful. Also the lectures were excellent.
I saw alpha rays like tiny lightening. It was neat.
