Abstract:
1. A method for liquid safety-detection with a radiation source, comprising the use of the radiation source, a shield type collimator, a post collimator, a detector, a data collector, a data processing computer, thickness measuring probing heads and a radiation shield; and having the main steps of: a) conveying an article to be detected into an operation zone within the radiation shield by a conveying mechanism; b) allowing a ray beam to be emitted from the radiation source located in the shield type collimator, to pass through the article to be detected, then to pass said post collimator, and to be received by the detector facing the ray beam; c) transmitting a data of a signal of a received ray beam to the data collector, by the detector; d) amplifying and forming the data of the signal of the received ray beam and transmitting such data to the data processing computer by the data collector, and transmitting a data collected by the thickness measuring probing heads mounted on both sides of the conveying mechanism to the data processing computer by the same; and e) processing a data from the data collector and a data from the thickness measuring probing heads and accomplishing an energy spectrum analysis of a penetrated ray beam of the detected article to derive the liquid density and atomic number of the detected article, comparing a result with densities and atomic numbers of dangerous articles in a existing database, and then visually displaying a detected information of the detected article, by the data processing computer.
