Abstract： |
A method for carrying out back scattering safety detection on liquid by radioactive source includes setting detected liquid article on rotary platform, enabling ray to pass said article then to cause Compton scattering at liquid surface, receiving scattered photon by detector through collimator and sending data being amplified by data collector to computer for obtaining liquid density of detected article, comparing obtained result to dangerous article density stored in databank and issuing alarm if it is found that detected article density is identical to dangerous one. |
