Higher Levels of Radiation in Tokyo Tap Water

As the crisis progresses at Japan's Daiichi nuclear reactors in Fukushima, authorities are struggling to determine the extent of radiation released and its health effects and to decide if and when the reactors should be entombed.

Nuclear Policy

The Nuclear Policy Program aims to reduce the risk of nuclear war. Our experts diagnose acute risks stemming from technical and geopolitical developments, generate pragmatic solutions, and use our global network to advance risk-reduction policies. Our work covers deterrence, disarmament, arms control, nonproliferation, and nuclear energy.

After Japan’s recent earthquake and subsequent tsunami triggered a crisis at Fukushima’s Daiichi nuclear reactors, Tokyo tap water has been declared sufficiently radioactive that the it should not be gievn to infants. Carnegie’s James Acton, speaking on Fox News’ Happening Now, explained that, barring further considerable releases of radiation from the Fukushima reactors, the radiation levels will decay steadily. One half of the remaining material decays every eight days, Acton said. At very low levels, exposure to radiation is not a problem and Acton added that the current levels of radiation in the Tokyo tap water are probably not dangerous to adults.

Acton also discussed the pressing question facing Japanese authorities of when and whether to entomb the reactors. He explained that the preferable scenario is for Japanese engineers to get the reactors under control and then encase them in concrete to prevent further radiation leakage.
