The results of a study conducted by the U.S. military show American servicemembers involved in the earthquake and tsunami cleanup in Japan were not exposed to dangerous levels of radiation or toxins, according to an article in the Stars and Stripes.

Thom Burke, the commanding officer of the Reagan, which said no crew members had been exposed to dangerous levels of radiation, and that the Reagan had repositioned itself away from the Fukushima plant for safety reasons.
