Method and apparatus for security detection of liquids

A method for security detection of a liquid, comprising the steps of: Transporting a to be inspected liquid article by means of a transport mechanism (3) in a path of a radiation source (12) emitted with low energy radiation beam between the radiation source (12) with low energy and a low-energy detector (18); penetrates and emit the radiation beam from the radiation source (12) with low power, collimating the emitted radiation beam from a collimator from the shield type (2), where the collimated radiation beam penetrates the to be inspected liquid article, then a Postkollimator (4) (of the low power detector 18 ), which faces the beam is received; Transmitting a data signal of the received beam to the data entry (6) of the low-energy detector (18); Conveying the member to be inspected liquid article by means of the transport mechanism (3) in a path of a radiation source (13) emitted with high energy radiation beam between the radiation source (13) with high energy and a high-energy detector (19); penetrates emitting the radiation beam from the radiation source (13) with high-energy collimating the emitted radiation beam from a further collimator of the shield type (2), where the collimated radiation beam penetrates the to be inspected liquid article, then another Postkollimator (4) and from the high-energy detector (19), which faces the beam is received; Transmitting a data signal of the received beam to the data entry (6) of the high-energy detector (19); Transmitting, after the data entry (6) processes the data signals from the received radiation beams from the low-energy detector (18) and the high-energy detector (19), the data thus formed on ...
