Neutron radiography

Could anybody tell me the density variation in a neutron radiograph for the BPI ( IQI), I would like to know which part will be higher density ( hole)& which part will be lower density ( say polyurethane foam).
If you have any example could you let me know

Thanks

Kumar

Dear Kumar

Again me, to be specific the following ASTM E545 would give an insight into the neutron attenuation factor for each IQI materials in question

ASTM E545
Standard Test Method for Determining Image Quality in Direct Thermal Neutron Radiographic Examination.
