日機場可能安裝透視探測器

Recently the Yomiuri News reported the following:

空機利用者の衣類の下を透視して、金属探知機には反応しない不審物を発見する装置「ボディースキャナー」について、国土交通省は８日、国内の空港で行っている保安検査の手段の一つとして認め、各航空会社が装置を検査に導入できるよう、今月中にも航空安全のガイドラインを変更すると発表した。
　発表によると、国土交通省は７～９月、ボディースキャナー５機種の実証実験を成田空港で実施。その結果、電磁波の一つ「ミリ波」を乗客に照射し、体の線を鮮明に映し出す１機種について、乗客らを検査員が直接触って確認する「接触検査」と同等の検知能力があると評価した。各航空会社が今後、導入するかどうかを判断する。

About the "Body Scanner" that could see through the clothes of air travellers, and to detect suspicious things that a metal detector could not discover, the Ministry of Land, Infrastructure and Transport announced on the 8th that the guideline on Airlines safety was changed so that scanners might be taken as one of the means for security inspection to be carried out in a domestic airports, and each airline may introduce this inspecting device by the end of this month.

According the announcement, the Ministry of Land, Infrastructure and Transport carried out the proving tests on five models of the body scanners in New Tokyo International Airport from July to September. As a result, it was evaluated that when the "Millimeter wave" , being one kind of the electro-magnetic radiation was radiated directly at the passenger, the body line was clearly projected, and it was confirmed that it had an equal sensing capability as "Contact Inspection" that the inspecting personnel could feel. In future, it would be up to individual airlines to decide whether to introduce it.

For security purpose, the installation of body scanners at the airport is understandable.
