Measurement of radioactive material concentration and air dose in landfill
In the wake of the accident at the Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station in 2011, Yokohama City measured the concentration of radioactive material inland water and effluent in landfill, as well as air dose at the boundary of the site. The results of these measurements are published on this page.

Measurement results
radioactive material has not been detected in wastewater in landfill, and air dose is about the same as measured at other locations in the city.

- The outer circumference of Minamihonmoku landfill is surrounded by seawalls with a waterproof function, so that inland water at the disposal site does not leak out. Since the start of measurement, radioactive material has not been detected in inflow and discharge water from wastewater treatment facilities to properly treat inland water in Minamihonmoku landfill.
- Regarding the Shinmeidai disposal site, the survey was completed in 2015 because "non-detection" of radioactive material concentration continued since the start of measurement.
