CONTAINERS AND SYSTEMS FOR THE MEASUREMENT OF RADIOACTIVE GASES AND RELATED METHODS

摘要

Containers for a fluid sample containing a radionuclide for measurement of radiation from the radionuclide include an outer shell having one or more ports between and interior and an exterior of the outer shell, and an inner shell secured to the outer shell. The inner shell includes a detector receptacle sized for at least partial insertion into the outer shell. The inner shell and outer shell together at least partially define a fluid sample space. The outer shell and inner shell are configured for maintaining an operating pressure within the fluid sample space of at least about 1000 psi. Systems for measuring radioactivity in a fluid include such a container and a radiation detector received at least partially within the detector receptacle. Methods of measuring radioactivity in a fluid sample include maintaining a pressure of a fluid sample within a Marinelli-type container at least at about 1000 psi.

1. A container for a fluid sample containing a radionuclide for measurement of radiation from the radionuclide, comprising:
an outer shell comprising one or more ports extending between an interior and an exterior of the outer shell; and an inner shell secured to the outer shell and comprising a detector receptacle sized for at least partial insertion into the interior of the outer shell, the inner shell and the outer shell together at least partially defining a fluid sample space proximate the detector receptacle, wherein the outer shell and inner shell are each configured for maintaining an operating pressure within the fluid sample space of at least about 1000 psi.
