amounts of explosives packaged in baggage. 205 The Department and TSA have faced similar<br />
challenges deploying checkpoint explosives detection equipment such as with advanced<br />
imaging technology. 206<br />
In some cases, TSA’s technologies have faced serious questions about safety and privacy.<br />
In 2013, TSA announced that it was removing the X-Ray scanning systems that had been<br />
deployed to airports, in response to concerns that the screening systems produced naked images<br />
of passengers and that TSA could not ensure that it was meeting privacy guidelines. 207 In all,<br />
DHS had acquired 251 of these machines at a cost of more than $41 million. 208 Others have<br />
questioned the safety of the machines, and whether TSA had satisfactorily studied any potential<br />
health risks before using the machines at airports. 209 Senator Coburn sponsored bipartisan<br />
legislation along with four members of the Committee in the 112 th Congress to require DHS to<br />

ultimately included in report language for an appropriations bill. In 2012, TSA announced it<br />
was commissioning an independent study of the machines. 211 In November 2014, the National<br />
Academy of Sciences reported that the study was planned to be released by January 2015. 212<br />
