Radiation in Ikebukuro
Radiation was detected at a park in Ikebukuro.
Something like a disk has come out under the park playground equipment.
This disk gave expensive radiation off.
If a disk is taken, radiation has returned to the normal value.
You can’t fix.
The company which probably installed this playground equipment took charge of constructing it in Fukushima, so when establishing, it seems to have got mixed up.
