METHOD FOR NON-DESTRUCTIVE DENSITOMETRIC MEASUREMENT OF SMALL VOLUMES INSIDE IRREGULARLY SHAPED NON-UNIFORM OBJECTS

In determining the electron density of a small selected volume inside an irregularly shaped non-uniform body using radiographic techniques there has always been a dependence on the absorption of radiation in the medium surrounding the selected volume. The present invention allows the measurement of...

Zusammenfassung:In determining the electron density of a small selected volume inside an irregularly shaped non-uniform body using radiographic techniques there has always been a dependence on the absorption of radiation in the medium surrounding the selected volume. The present invention allows the measurement of the electron density of a small volume within a non-homogeneous medium by manipulation of the apparatus. This manipulation removes the dependence of the measurement on the absorption of the X-ray or gamma-radiation in the surrounding medium.
