riporto le info fornite da Luuk della Scionix a rigurado:
It was used with a radioactive source mounted in the center of the detector the source was collimated so that the radiation went 180 Degrees away from the detector , Then the detector detected the backscattering from material in front of the detector when “hidden” material e.g. an explosive such as Semtex or other “plastic” explosives they contain lots of hydrogen that will give a different backscattering signal then when there is no hidden material.
It is a well known technic also used to detected drugs hidden in e.g. car doors.
