Description

The radiation environment inside residential houses was measured at MinamiSoma-shi and Iitate-mura in Fukushima Prefecture. The average measured reduction coefficients, which are the ratios of the indoor and outdoor ambient-dose-equivalent rates were 0.35 and 0.45 at the centers of the first and second floors, respectively. The indoor dose rates on the second floors were larger than those on the first floors. The indoor dose rates increased with measurement height. The indoor and outdoor photon energy spectra were measured, revealing that the indoor scattered photon component is larger than the outdoor one. (author)
