I monitored radiation around Gohyakubuchi-park of Koriyama city, Fukushima Prefecture, Japan.

Space dose of the height of the chest of the promenade circling the pond, was approximately 0.27 to 0.30 micro sievert per hour.

At the entrance of the park, a sighnboad shows the decontamination result by the city.
Before the decontamination: 2.33 micro Sv/h as of Sep of 2011
After the decontamination: 0.21 micro Sv/h as of Jun of 2016
(Air dose rate 50cm high from the ground level)

My monitor shows space dose 0.47 on the pond-side promenade near a floodgate to the waterway into the woods.

Space dose on the promenade in the park forest is at the height of the breast, was 0.3 to 0.45 micro Sv/h

To the waterside in the forest, there is a hot spot that radioactive material is collected.
Approaching to the place, the value of the dosimeter is jumped.
Space dose of the height of the breast in the hot spots were recorded 1.5-1.9 micro Sv/h.

Measuring instrument that was used during the video shoot, Ukraine made, ECOTEST’s MKS-05.
Koriyama city : population, about 330,000 people.
