Evaluation of the radiation effect on building highway subgrade using 137Cs slightly polluted soil after nuclear power plant accidents

After the accident at Fukushima nuclear power plant in Japan, a large amount of radioactive contaminated soil was generated, which brought great challenges for treating and disposing soil. The recycling slightly polluted can reduce This paper analyzes main exposed scenes 137Cs used construction highway subgrade, bag handling paving. Monte Carlo algorithm (MCNP) RESRAD-ONSITE program are to simulate two respectively, concentration is derived effective dose 1 mSv per year. It concluded that: annual doses porter paver 0.41 year 0.23 respectively caused by Bqg-1 soil; activity 2.44 4.26 paver; calculated results consistent with those reported Japan Atomic Research Agency. Also, they lower than corresponding control level under low-probability events IAEA No. RS-G-1.7 slightly.
