Parent radionuclide container

1. A method comprising:

providing a radiation impervious case;

disposing a vial that holds a parent radionuclide within the case;

venting the vial through a filter in a stopper that is external to the case along a curved path through the case between the filter and the vial and where the curved path eliminates any line of sight radiation leakage from the vial through the stopper; and

connecting a fill tube between the vial and external stopper, said fill tube at least partially following the curved path of the vent.

2. The method as in claim 1 further comprising removing the parent radionuclide from the vial by inserting a fluid withdrawal tube through the fill tube.

3. The method as in claim 1 further comprising dividing the radiation impervious case into two parts and providing an offset in a line of separation to eliminate line-of-sight radiation from escaping through seams in the container.

4. An apparatus comprising:

a radiation impervious case;

a vial for a radionuclide disposed within the case;

a stopper with a central bore, the central bore aligned at an oblique angle with respect to the case so that a straight line through the central bore does not pass through any part of the vial; and

a curved tube that connects the central bore of the stopper and a cap of the vial.

5. The apparatus of claim 4 wherein the radiation imperious case further comprises first and second halves divided by a dividing line with an offset that prevents line-of-sight radiation from escaping along the dividing line.

6. The apparatus of claim 4 further comprising a vent passageway extending from the central bore of the stopper into an opposing side of the radiation impervious case.

7. The apparatus of claim 4 further comprising a second tube with a relative smaller outside diameter than an inner diameter of the curved tube, the second tube being inserted into the vial through the curved tube to remove a parent radionuclide from the vial.

8. An apparatus comprising:

a container suited for a parent radionuclide, the container further comprising:

a radiation impervious case;

a vial disposed within the radiation impervious case that holds the parent radionuclide within the case;

a passageway extending along a curved path between the vial and a stopper that is external to the case; and

a fill tube that extends along the passageway between the vial and external stopper, said fill tube at least partially following the curved path of the vent.

9. The apparatus as in claim 8 further comprising a fluid withdrawal tube extending through the fill tube that removes the parent radionuclide from the vial.

10. The apparatus as in claim 8 further comprising the radiation impervious case divided into two parts and an offset provided in a line of separation to eliminate line-of-sight radiation from escaping the container.
