This standard applies to non-intrusive inspection (NII) systems
\nusing active interrogation methods for the detection of contraband
\n(drugs, explosives, and weapons of mass destruction [WMD]).
\nHighenergy neutrons have been used for such purposes but other
\nmethods are being developed that use high-energy photons as well.
\nIn particular, this standard covers the safety aspects of active
\ninterrogation systems, henceforth called "systems," using, but not
\nlimited to, high-energy x-rays (bremsstrahlung) produced by
\nhigh-energy electron linear accelerators, high-energy neutrons
\nproduced by the (d,d) and (d,T) reactions, fission neutrons from
\n252Cf, highenergy neutrons produced by (?,n) reaction in linear
\naccelerators using Be\/W targets, or other accelerator methods for
\nproducing high-energy photons and neutrons. (In this standard, the
\nterm high-energy photons is used to mean high-energy x-rays and
\ngamma rays in the MeV range of energies.)<\/p>\n
The maximum energy of the ionizing radiation used for
\ninterrogation by these systems is limited to 100 MeV because the
\nuse of general-purpose active interrogation systems employing
\nenergies greater than this level is not expected in the foreseeable
\nfuture.<\/p>\n
This standard does not apply to conventional security imaging
\nsystems using x-rays and gamma rays. However, it includes hybrid
\nsystems combining active interrogation systems with conventional
\nsecurity imaging systems. In that case, a hybrid system capable of
\ndoing both functions shall meet the standards of both types of
\nsystems.<\/p>\n
This standard does not apply to general safety involving
\nmechanical failure, electrical shock, chemical explosion, gases
\nunder pressure, and noxious gases. It also does not apply to
\npossible damaging effects of ionizing radiation to foods, medical
\ndevices, pharmaceuticals, photographic films and papers, and
\nmicroelectronic devices containing computer chips.<\/p>\n","protected":false},"excerpt":{"rendered":"
