Britain’s nuclear reactors, stainless steel drums, contain metal-clad spent uranium embedded in concrete, and they are highly radioactive. The only way to handle them safely is from behind 2-to-3-meter-thick concrete walls and leaded glass windows using automated equipment. Yet a very small number of these drums have begun to bulge after many years in storage, raising questions about what is happening within. The only way to know for sure is to sneak a peek inside.

He presented his research today at the 247th National Meeting & Exposition of the American Chemical Society.
(Lebanon, NH 2/18/14) —How would a city, state, or country handle a disaster in which hundreds of thousands of people were exposed to radiation? When the number of people involved exceeds the capacity of nearby hospitals, how would a community know who to treat? In a new scientific review published on February 12, 2014 in Radiation Environmental Biophysics, Dartmouth researchers say that by examining a person’s teeth or fingernails with specialized equipment, it is possible for first responders to estimate radiation exposure and identify those with the highest risk of illness. The review makes the case for field-based equipment that can easily and quickly allow first responders to decide who needs treatment for radiation exposure in a large-scale event such as major nuclear power plant malfunction or terrorism.

In 2012, Nicholas Fisher a distinguished professor in the School of Marine and Atmospheric Sciences (SoMAS) at Stony Brook University and postdoctoral scholar Zosia Baumann, working with a colleague at Stanford University’s Hopkins Marine Station, reported that they had detected radioactivity in Pacific bluefin tuna swimming off the California coast. The source of the radioactivity was Japan’s Fukushima Dai-ichi powerplants, which were damaged by the strong earthquake and subsequent tsunami on 11 March 2011 and released large quantities of radioactivity into the Pacific Ocean. The news prompted widespread media interest and speculation as to the possible risks to seafood consumers posed by the levels of radioactivity found in the tuna.
