Helen Grogan and other members of the National Council on Radiation Protection and Measurements (NCRP) Scientific Committee 3-1 on Emergency Response Dosimetry were very fortunate to be given a tour of the Hudson River and the East River on Fire Boat 343. This is a rescue boat complete with an air-purification system that went into operation in 2010 and can operate in areas tainted by chemical, biological, or nuclear agents. Its four pumps can spray a combined 50,000 gallons of water per minute at 150 psi—twice the capacity of older ships.
