Japanese Nuclear Emergency: Radiation Monitoring
RadNet Data for Trenton, New Jersey
This site contains information and data from March 11, 2011 to June 30, 2011. EPA has returned to routine RadNet operations. This site will continue to be available for historical and informative purposes.

Laboratory Data
In the tables below we provide sampling results for:
Milk
The milk sampling results are far below the Food and Drug Administration's Derived Intervention Level for iodine-131 in milk. These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children. Iodine-131 has a very short half-life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly.
Drinking Water
Drinking water samples collected by EPA since the Japanese nuclear incident have shown radioactive material at levels well below public-health concern. Similar findings are to be expected in the coming weeks.
