Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
Shielding holder for a container or receptable having longitudinally extending scale means for determining the amount of radioactive material disposed therin comprising, a holder portion of high density material and of generally U shaped configuration, said holder being provided with a generally cylindrical bore extending generally eccentrically longitudinally there-through to receive said container and having a slot extending generally longitudinally, for at least a portion of the length of said high density portion, and through the thickest portion thereof, and into communication with said eccentric bore, a rectangular insert of transparent material disposed within said slot, said transparent material comprising a high density glass, and cover means for said bore of high density material, whereby the amount of radioactive material held within said container may be visually perceived and quantitatively ascertained.
Claim 2
Dependent Claim
131 words
