Logan International Airport in the US will receive 60 additional explosive detection units as part of the US Homeland Security's decision to buy 1,200 units for the country's airports.
The Homeland Security secretary Janet Napolitano said $35.5m in American Recovery and Reinvestment Act (ARRA) funding will be used to buy the explosives detection units.
Logan airport, which is already using 50 of the devices, will receive the additional explosive detection units by early summer, Napolitano said.
"These state-of-the-art technologies will strengthen security and streamline screening operations while making air travel more convenient for passengers," Napolitano said.
"Explosives trace detection technology, enhanced inline baggage screening systems and improved surveillance capabilities are important elements of our layered aviation security strategy to protect the flying public from terrorism."
Homeland Security will also spend $6.1m in ARRA funds to purchase 135 chemical analysis devices.
The devices will be used to detect possible explosives in liquids that are brought through security checkpoints at airports.
