Abstract
Abstract A radiation-shielding receptacle for holding a glass bottle for receiving the eluate from the elution of a radioactive material is disclosed. The receptacle includes a hollow cylindric body of nontransparent radiation-shielding material having a window opening in its wall. A first end closure of radiation-shielding material is provided at one end of the body and a second end closure of radiation-shielding material is provided at the other end of the body. The second end closure has a central opening therein smaller than the internal diameter of the body and of a size so that the mouth of a bottle positioned in the body is exposed to receive the eluate. An insert of substantially transparent radiation-shielding material is secured in and fills the window opening so that the eluate in a bottle in the body may be viewed from the outside. The thickness of the body and the thickness of the insert are sufficient to provide a substantial amount of shielding against radioactive emission from the eluate.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
161 words
A radiation-shielding receptacle for holding a transparent vessel having a neck for receiving the eluate from the elution of a radioactive material, said receptacle comprising a hollow body of nontransparent radiation-shielding material having upper and lower end closures of radiation-shielding material, one of said end closures being removably attached to said body, the upper end closure having a central opening therein smaller than the internal cross section of the body and extending completely through said upper end closure for receiving the neck of the vessel with the neck extending upwardly out of the receptacle through said opening for access to the mouth of the vessel for the elution operation, the wall of said body having an elongate window opening therein extending in the direction of the height of the body, and an insert of substantially transparent radiation-shielding material in said window opening for viewing of the eluate in a vessel in the receptacle while shielding against radioactive emission from the eluate.
Claim 2
Dependent Claim
161 words
A radiation-shielding receptacle for holding a transparent vessel having a neck for receiving the eluate from the elution of a radioactive material, said receptacle comprising a hollow body of nontransparent radiation-shielding material having upper and lower end closures of radiation-shielding material, one of said end closures being removably attached to said body, the upper end closure having a central opening therein smaller than the internal cross section of the body and extending completely through said upper end closure for receiving the neck of the vessel with the neck extending upwardly out of the receptacle through said opening for access to the mouth of the vessel for the elution operation, the wall of said body having an elongate window opening therein extending in the direction of the height of the body, and an insert of substantially transparent radiation-shielding material in said window opening for viewing of the eluate in a vessel in the receptacle while shielding against radioactive emission from the eluate.
Claim 3
Dependent Claim
20 words
A radiation-shielding receptacle as set forth in claim 1 wherein the lower end closure is removably attached to the body.
Claim 4
Dependent Claim
31 words
A radiation-shielding receptacle as set forth in claim 2 wherein the body is of hollow cylindric form and the lower end closure is threaded in the lower end of the body.
Claim 5
Dependent Claim
30 words
A radiation-shielding receptacle as set forth in claim 3 wherein the upper end closure is constituted by an integral inwardly directed annular flange at the upper end of the body.
Claim 6
Dependent Claim
64 words
A radiation-shielding receptacle as set forth in claim 4 wherein the body is made of lead and has an internally threaded ring of a harder metal than lead secured therein at its lower end, and the lower end closure comprises a plug of lead having an externally threaded ring of a harder metal than lead secured therearound and threaded in the internally threaded ring.
Claim 7
Dependent Claim
22 words
A radiation-shielding receptacle as set forth in claim 5 wherein the plug has a flange extending outwardly below the externally threaded ring.
Claim 8
Dependent Claim
21 words
A radiation-shielding receptacle as set forth in claim 1 having a removable cover of radiation-shielding material overlying the upper end closure.
Claim 9
Dependent Claim
46 words
A radiation-shielding receptacle as set forth in claim 1 for holding a glass bottle having a neck wherein the opening in the upper end closure is larger than the neck and the height of the receptacle is such that the neck extends upwardly through the opening.
Claim 10
Dependent Claim
55 words
A radiation-shielding receptacle as set forth in claim 8 wherein the body is of hollow cylindric form, the upper end closure is constituted by an integral inwardly directed annular flange at the upper end of the body, and the lower end closure is constituted by a plug threaded in the lower end of the body.
Claim 11
Dependent Claim
36 words
A radiation-shielding receptacle as set forth in claim 9 wherein the window opening is constituted by a slot extending down from the upper end of the body terminating short of the lower end of the body.
Claim 12
Dependent Claim
26 words
A radiation-shielding receptacle as set forth in claim 10 wherein the body and closures are made of lead, and the insert is made of lead glass.
Claim 13
Dependent Claim
20 words
A radiation-shielding receptacle as set forth in claim 11 wherein the insert is thicker than the wall of the body.
Claim 14
Dependent Claim
53 words
A radiation-shielding receptacle as set forth in claim 12 having a cover of radiation-shielding material for the upper end of the receptacle, the latter having an annular rib around the central opening therein and the cover having a recess for receiving the rib and the upper end of the neck of the bottle.
