Japan Crisis Not As Bad As Chernobyl

As Japanese authorities work to cool the nuclear reactors damaged by the earthquake and tsunami, it remains unclear how much radiation is being released into the environment.

As the crisis deepens at the Daiichi reactors in Fukushima, Japanese authorities are working to cool the reactors and limit the spread of radiation. The severity of the situation is both unclear and fluid, since measuring gauges at the Daiichi reactors are unreliable and radiation levels have fluctuated greatly on-site. Speaking on NBC’s Today Show, Carnegie’s James Acton describes the Fukushima reactor crisis as worse than Three Mile Island, though less disastrous than Chernobyl. During the Chernobyl catastrophe, Acton said, a significant fraction of the reactor core explosively spread into the environment. In Japan, the primary threat comes from the melting of the reactor core, exposing fuel rods to the atmosphere. The amount of radiation that will be released from such melting is unclear, Acton concluded.

    EU-Iran: Time to Revisit Assumptions and Strategize

    For too long, the EU focused on Iran’s nuclear program while mostly ignoring its malign regional activities and missile program. As the consequences of both hit closer to home, the union must pursue a new strategy focused on containing Iran’s regime, supporting Iranian civil society, and engaging with Gulf states.
