Summary :
|
|
THIS PAPER PRESENTS A STUDY OF A TRANSPORTABLE NEUTRON RADIOGRAPHY SYSTEM UTILIZING CALIFORNIUM-252. STUDIES ABOUT MODERATION, COLLIMATION AND SHIELDING ARE SHOWED. A MONTE CARLO CODE, MCNP3B, HAS BEEN USED TO OBTAIN A MAXIMUM AND MORE HOMOGENEUOS THERMAL NEUTRON FLUX IN THE COLLIMATOR OUTLED NEXT TO THE IMAGEM PLAIN, AND AN ADEQUATE RADIATION SHIELDING TO ATTEND RADIOLOGICAL PROTECTION RULES. WITH THE PRESENTED COLLIMATOR, IT WAS POSSIBLE TO OBTAIN FOR THE THERMAL NEUTRON FLUX, AT THE COLLIMATOR OUTLET AND NEXT TO THE IMAGE PLAIN, A L/D RATIO 7,5, FOR NEUTRON FLUX UP TO 6.10(-6)/CM(2).S. |
