The Radiological Health Program evaluates and manages the actual and potential public health impacts on Vermonters from activities at the Vermont Yankee Nuclear Power Station, located in the town of Vernon in Windham County.
Tritium Contamination Investigations
Tritium is a radioactive form of hydrogen. It is a byproduct of the nuclear fission process in a nuclear reactor and occurs naturally in the environment at very low concentrations. Most tritium in the environment is in the form of tritiated water, which easily moves about in the atmosphere, bodies of water, and in soil and rock.
On January 7, 2010, the Health Department was notified by Vermont Yankee Nuclear Power Station that samples taken from a groundwater monitoring well on site at the plant contained tritium.

Environmental Surveillance and Monitoring reports
Regular sampling is done around the power station to test for radioactive contamination. Samples are taken from:
- Surface water
- Connecticut River sediment
- Fish from the Connecticut River
Local farms also provide milk samples every month for testing to verify there are no radiological contaminants in the milk. Analysis of samples is done at the Health Department Laboratory.
The Health Department continuously measures the radiation dose around Vermont Yankee, both at the site boundary as well as locations throughout Windham County.
Environmental surveillance has been in effect since before Vermont Yankee began commercial operation in 1973. The Health Department publishes an annual report of its surveillance findings—see the reports in the table below.
In 2005, there was an investigation into whether the State’s radiation limit at the Vermont Yankee site boundary had been exceeded. A third party was brought in to conduct the investigation and found Vermont Yankee had not gone over the site boundary radiation dose limit. Read the investigation

The Health Department partners with the following state agencies and departments to help ensure Vermonters are provided adequate warning and emergency response in the event of a radiological release at Vermont Yankee:
Health Department staff train emergency responders throughout the state in the essential skills required in emergency events and staff critical positions in local and state emergency operations centers. In addition to meeting classroom and field training requirements, Health Department staff participate in annual drills to test their ability to use their learned skills.
