  • Radiation exposure while traveling on Joban Expressway ~Radiation exposure per trip~

Radiation dose received when traveling on Joban Expressway between Hirono IC and Minamisoma IC.

Between Hirono IC and Minamisoma IC (if passing through the evacuation zone)

Based on the ambient dose rate (μSv/h) between Hirono IC and Minamisoma IC (49.1 km), the radiation dose received by a driver or other person when traveling through the area once at a speed of 70 km/h is calculated.

In the case of automobiles
0.28 μSv/h (approximately 1/210) *1
In the case of motorcycles
0.34 μSv/h (approximately 1/170th) *1
  • [Reference] Radiation levels encountered in daily life: Comparison with the radiation dose from mass chest X-ray screenings (60 μSv = 0.06 mSv)

The above radiation doses were calculated using the "Detailed Monitoring Results in Evacuation Zones (26th Round of Driving Surveys by Monitoring Vehicles) (November 2016)" conducted by the Cabinet Office's Nuclear Disaster Victims' Livelihood Support Team and the Nuclear Regulation Authority, with the technical cooperation of the Cabinet Office's Nuclear Disaster Victims' Livelihood Support Team, and the dust sampling survey results conducted by NEXCO EAST (January 2017).
