Yup. That's what it says in my notes from the army's NBC (Nuclear, Biological & Chemical Warfare) school. Does it say differently in the essay? I didn't write that, I got it from Global Security Newswire last year.

SHELTERING IN PLACE INFO --
SNIP:
If you do not want to trust in weather and traffic, the alternative is what the experts call “sheltering in place.” You want to be in a building, as solid as possible to block the gamma rays, as airtight as possible to keep out radioactive dust. You need to turn off air conditioning, close vents, seal the seams around windows and doorways. If you wondered what former Homeland Security Secretary Tom Ridge was talking about, this is what you need the duct tape for. Abandon rooms with windows broken by the blast.
The dust that does not seep into the building will settle outside, on the roof and on the ground, emitting gamma rays. A car with an intact windshield stops 30 to 50 percent of the radiation — probably not enough, however, to save someone who’s inside the car and stuck in traffic a few miles downwind of ground zero.
A wood-frame house, similarly, stops just 30 to 60 percent of gamma rays. A windowless basement stops 90 percent. The middle floors of a concrete apartment building, safely away from both roof and ground, stop 99 percent or more. But there is no 100 percent protection.
For those whom evacuation and shelter fail — or for those, like the thousands fleeing in blind panic, who never try either — there is still decontamination. A lethal dose of radiation takes time to build. The sooner the radioactive dust is off the skin, the better. And it is not that hard to remove. “Radiation contamination is easier than chemical,” said Col. David Jarrett, a medical doctor and the director of the Armed Forces Radiobiology Research Institute in Bethesda. “Simply removing the clothes and washing takes off up to 90 percent.”
Every major Washington-area hospital has some decontamination facilities, but 10,000 radiation patients in one day would swamp them. So mass decontamination falls to fire departments, with their mobile pumps and generators; their protective gear; their hazardous-materials experience; and, because both Maryland and Virginia have nuclear power reactors, their years of radiation training. Area firefighters can quickly set up special decontamination tents, and they have plans to take over buildings that have lots of showers — so high school gyms, for example, are a good place to head for. In the chaos of those first hours, said Michael Cline, state coordinator at the Virginia Department of Emergency Management, “the real key is to make sure people go to those facilities.” It will take every firefighter available to man the decontamination sites, and every cop to control the crowds pouring in panic out of the city.
