An XRF analyzer can include an x-ray source and an x-ray detector; an x-ray source heat-sink adjacent a side of the x-ray source; and an x-ray detector heat-sink adjacent a side of the x-ray detector. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a material having a thermal conductivity of less than 20 W/(m*K). In another embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by at least 3 millimeters of a thermally insulating material. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a segment of the engine component casing. Separation of the heat sinks can help avoid heat from the x-ray source adversely affecting resolution of the x-ray detector.

A portable gamma ray computed topography (CT) device configured to capture images includes a projector, a collimator, and a detector. The projector includes an isotope encapsulated within a depleted uranium, and the collimator is affixed to the projector eliminating use of a guide tube. The apparatus also includes a crank cable affixed to the isotope, and is configured to extend the isotope out of projector and into the collimator. The apparatus further includes a detector configured to capture multiple shots on order of hundreds of shots to create a three-dimensional (3D) reconstruction from infield gamma ray images.

A portable XRF analyzer includes a hand shield and a handle. In one embodiment, the XRF analyzer further comprises a power component spaced-apart from an engine component. The handle and the hand shield extend in parallel between the engine component and the power component, attaching the engine component to the power component. In another embodiment, the XRF analyzer further comprises two housing portions, each integrally formed in a single, monolithic body formed together at the same time. The two housing portions are joined together to form an XRF analyzer housing. In another embodiment, the hand shield is shorter than the handle.

A radiation source holder holds a source carrier in a passageway such that a capsule in the source carrier it may be linearly positioned in an ON or OFF position to control emission of gamma radiation from the source holder. Linear and rotary cams having linear and rotary cam surfaces interact with cam guides on the source carrier so that linear movement of the source carrier and capsule between said ON and OFF positions can be effected by rotation of the rotary cam.

Systems and methods for distribution, storage, transport, administration and/or disposal of one or more therapeutic or diagnostic agents are disclosed. A storage device configured to connect to a delivery system for delivering the therapeutic or diagnostic agent has a housing with a chamber, a vessel having an access port positioned within the chamber. The door is movable relative to the housing between a closed position and an open position. In the closed position, the door covers an opening in the housing to enclose the chamber, and, in the open position, the door reveals the opening for accessing the access port of the vessel. The door is moveable between the closed position and the open position in response to actuation by an access mechanism of the delivery system.

Example remote controls for radiographic sources include: a drive cable configured to detachably couple to a radiographic source via a connector; a drive gear configured to advance the drive cable in a first direction toward the connector and to retract the drive cable in a second direction away from the connector; a control conduit configured to guide a portion of the drive cable located between the drive gear and a radiographic source housing; and a drive cable storage drum on an opposite side of the drive gear from the control conduit, and configured to store a portion of the drive cable.
