Neutron radiography applied to the microorganisms detection

This work aims to present a new method of microorganism detection in several culture medium, such as potable water and corporal fluids. After the steps of processes of growth in culture medium, separation and resuspension in a boron based lid solution, the microorganisms are deposited in lines detectors and at last submitted to a thermal neutrons beam (congruent with 2.2x105 n/cm2.s). The latent tracks registered by the alpha particles coming from the B(n,α)Li reaction are analyzed by an optical microscope, allowing the detection of microorganisms existence
