Local emergency responders in New Jersey recently received a big boost in disaster preparedness from DHS; last week the county unveiled a new 3,000 square foot mobile structure comprised of interlocking tents and trailers; the tents can be quickly set up to treat victims of a radiological accident, terrorist attack, pandemic, or weather emergency; the tent system can also be outfitted with its own water supply, power generator, and heating and cooling systems. They are even equipped with lights, showers, sinks, and a kitchen; for training purposes, the tents were set up at the Middlesex County College campus; the portable structure, called the Gatekeeper system, cost $1 million and was paid for with DHS grant money; county officials also received DHS grants to purchase mobile radiation detection devices for police officers; the tents and the radiation detectors come as part of a broader government effort to prepare local law enforcement agencies within a forty-five mile radius of New York City for a dirty-bomb attack
