The major international airport of the Netherlands will begin using full-body scanners on passengers flying to the United States to prevent a recurrence of the security breach that allowed a would-be bomber to smuggle explosives onto a flight to Detroit from Amsterdam on Christmas Day, the Dutch authorities said Wednesday.

Although Dutch officials said they would deploy the scanners “immediately,” a spokesman for the country’s counterterrorism office said that only 7 of the 15 full-body scanners at the airport, Schiphol, were ready for use. The rest are to be deployed within three weeks after receiving software upgrades.

The interior minister, Guusje ter Horst, said the United States had previously not wanted Amsterdam to use the full-body scanners, which look through clothing and show the outlines of the body, because of privacy concerns. But Ms. ter Horst said there was now agreement with Washington that “all possible measures will be used on flights to the U.S.”

Judith Sluiter, spokeswoman for the Dutch national coordinator for counterterrorism, said Sunday that the “Dutch authorities have not been given permission to use them on passengers for U.S.-bound flights.”
