Seoul National University, KOREA


Worry about fukushima f allout

Worry about Fukushima fallout

  • Radioactive rain in Korea?

    • I-1310.385~2.77mBq/㎥,

    • Cs-137 0.538~0.988mBq/㎥


1 msv is not safe

Anti-nuclear Doctors

1 mSv is not safe

  • Cancer risk

    • 1% for 100 mSv means 1/10,000 for 1 mSv

    • 5,000 cancer incidence out of 50,000,000 population in Korea

by LNT(Linear No Threshold) model


R adiation from asphalt road in seoul

Radiation from asphalt road in Seoul

  • Amember of Child Save detected using survey meter

  • Korea Institute of Nuclear Safety investigated

    • Cs-137 22~30 Bq/g

    • 2~3 microSv/hr on the surface

    • 0.5 mSv/year assuming 1 hour exposure/day


Safety management act for daily life radiation

Safety Management Act for Daily Life Radiation

  • the safety management system on the materials and products which include natural radionuclide, and establishes the protection system from the materials and recycled metals over certain level of radiation concentration  by installing the machines to detect radiation and radioactivity at the airport, ports and etc. 

  • the safety management system for cockpit crew and flight attendants who may be exposed to space radiation.
