Russell Hardy, the director of the Carlsbad Environmental Monitoring and Research Center, said that the levels of americium and plutonium were the highest ever recorded at that site.
Dan Hancock, the director of the Nuclear Waste Safety Program in Albuquerque, posed the questions, "Does anybody really know what happened in the underground [site] and how much [radiation] was released or is continuing to be released? And therefore, how much is being captured by the filters and how much is getting into the environment?"
In addition, one of RadCast's contributors reported levels spiking to 108 counts per minute yesterday, despite being 200 miles down-wind of that plant. It appears this leak may be more serious than officials are letting on, and RadCast will continue monitoring this situation closely.
