The first of 150 full-body scanners planned for US airports will be installed in Boston, Massachusetts, next week.
The plan is to install three machines at Logan International Airport, according to a homeland security official who spoke on condition of anonymity because the announcement has not yet been made.
In the coming two weeks, officials plan to install another machine at Chicago's O'Hare International.
