Abstract
Abstract A receptacle for storing radioactive material includes three concentric cylindrical casings of radiation shielding material, a container of radioactive material being received within the innermost casing, and a cover member or members forming a closure for the casingswhich are open at the top. Two of the casings and the cover member or members are of non-transparent radiation shielding material, such as lead, and the third casing is of transparent radiation shielding material, such as leaded glass. One of the non-transparent casings is movable with respect to the other non-transparent casing so that windows in each of the non-transparent casings can be aligned by the relative movement therebetween to permit the viewing of the material level within the container.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A receptable for storing a radioactive material container comprising an outer casing of radiation shielding material, an intermediate casing of radiation shielding material, an inner casing of radiation shielding material, said radioactive material container situate in said inner casing, two of said casings being of non-transparent radiation shielding material and the third said casing being of transparent radiation shielding material, and means effective to move one of said non-transparent casings with respect to said other non-transparent casing, said non-transparent casings each including viewing means which can be aligned by relative movement of said non-transparent casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 2
Dependent Claim
114 words
A receptable for storing a radioactive material container comprising an outer casing of radiation shielding material, an intermediate casing of radiation shielding material, an inner casing of radiation shielding material, said radioactive material container situate in said inner casing, two of said casings being of non-transparent radiation shielding material and the third said casing being of transparent radiation shielding material, and means effective to move one of said non-transparent casings with respect to said other non-transparent casing, said non-transparent casings each including viewing means which can be aligned by relative movement of said non-transparent casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 3
Dependent Claim
104 words
A receptacle for storing a radioactive material container comprising an outer casing of non-transparent radiation shielding material, an inner casing of non-transparent radiation shielding material, said radioactive material container situate in said inner casing, an intermediate casing of transparent radiation shielding material received between said inner and outer casings, and means effective to move one of said outer or inner casings with respect to said other, said outer and inner casings each including viewing means which can be aligned by relative movement of said casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 4
Dependent Claim
104 words
A receptacle for storing a radioactive material container comprising an outer casing of non-transparent radiation shielding material, an inner casing of non-transparent radiation shielding material, said radioactive material container situate in said inner casing, an intermediate casing of transparent radiation shielding material received between said inner and outer casings, and means effective to move one of said outer or inner casings with respect to said other, said outer and inner casings each including viewing means which can be aligned by relative movement of said casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 5
Dependent Claim
45 words
The receptacle of claim 2 including cover means, said casings being open at their tops and said cover means forming a closure therefor, said cover means being connectable to and effective to move one of said outer or inner casings with respect to said other.
Claim 6
Dependent Claim
97 words
A receptable for storing a radioactive material container comprising an outer casing of non-transparent radiation shielding material, an intermediate casing of non-transparent radiation shielding material, an inner casing of transparent radiation shielding material, said radioactive material container situate in said inner casing, and means effective to move said outer casing with respect to said intermediate casing, said outer and intermediate casings each including viewing means which can be aligned by relative movement of said outer and intermediate casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 7
Dependent Claim
97 words
A receptable for storing a radioactive material container comprising an outer casing of non-transparent radiation shielding material, an intermediate casing of non-transparent radiation shielding material, an inner casing of transparent radiation shielding material, said radioactive material container situate in said inner casing, and means effective to move said outer casing with respect to said intermediate casing, said outer and intermediate casings each including viewing means which can be aligned by relative movement of said outer and intermediate casings to establish a view path into the interior of said inner casing to perceive radioactive material in said container.
Claim 8
Dependent Claim
22 words
The receptacle of claim 4 wherein said viewing means comprises windows in said casings, said windows being parallel to said casings' axes.
Claim 9
Dependent Claim
13 words

Claim 10
Dependent Claim
14 words
The receptacle of claim 4 wherein said inner casing is fabricated from leaded glass.
Claim 11
Dependent Claim
15 words
The receptacle of claim 4 wherein said outer, intermediate and inner casings are concentric cylinders.
Claim 12
Dependent Claim
62 words
The receptacle of claim 4 wherein said outer, intermediate and inner casings are concentric cylinders, and said viewing means comprises a pair of windows in each of said outer and intermediate casings, said windows being generally rectangular and elongated parallel to said cylinders' axes with said pair of windows in each of said casings disposed at opposite ends of a casing diameter.
Claim 13
Dependent Claim
23 words
The receptacle of claim 4 including cover means, said casings being open at their tops and said cover means forming a closure therefor.
Claim 14
Dependent Claim
