A source container for a radiation source includes a vessel having an external wall defining a space within which is located a shield formed from a radiation absorbing material and defining a cavity for receiving a radiation source, the shield including a window extending from the cavity through the radiation absorbing material, and at least two shutters, each shutter being movable between a closed position in which the shutter covers the window and an open position in which the shutter does not cover the window. The provision of two or more shutters provides a way to emit radiation of different intensities from the same source and container.

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 radiographic projector for housing and projecting a radioisotope for use in radiography is described. The front end of the projector has a chamfered surface for receiving an ancillary shielding component. The material used for the front end surface of the projector is tungsten powder in a less dense material matrix. A locking mechanism for a projector is described, including a locking bar for locking a source holder in the projector. The locking mechanism includes an interlock section for retaining the locking bar in an unlocked position while a source holder is not in its storage position, and a latch section for latching the locking bar in the unlocked position prior to engagement of the interlock section. A holster for mounting a radiographic projector and a refraction cage for a remote windout mechanism are also described.

An apparatus used for training purposes contains an external casing, a primary shielding, a secondary shielding, and a control rod. The primary shielding and the secondary shielding are positioned within the external casing. The control rod and the secondary shield are used to adjust the radiation levels emitted from a radiation source placed within a hollow cylindrical portion of the control rod. A first rod receiving hole traverses the primary shielding. Likewise, a second rod receiving hole traverses the secondary shielding. The first rod receiving hole and the second rod receiving hole are concentrically aligned with a central receiving hole of the external casing to form a channel for the control rod to be slidably positioned.

In general, radiation shielding systems that shield radiation from multiple directions are described. In one embodiment, a method of shielding radiation is provided, including supporting a shielding device on an object proximate a radiation source, positioning a first shielding portion in a vertical position relative to the object, positioning a second shielding portion to extend away from the first portion, the second shielding portion attached to the first portion, and shielding radiation from the radiation source by the first shielding portion and the second shielding portion such that the first and second shielding portions provide a radiation shielding zone for a healthcare practitioner.

An example radiographic source exposure device includes: a housing; a radiographic source capsule within the housing, the radiographic source capsule having a radionuclide; a shield within the housing and configured to shield the radiographic source capsule and to permit extension of the radiographic source capsule to expose the radiographic source capsule; one or more sensors coupled to the housing, the one or more sensors configured to detect sensor data comprising one or more of: a count of exposure cycles, a length between the radiographic source capsule position and a stored position, a surface dose, a source decay of the radiographic source, a locking device locking mode status, an unlocking key status, a radiographic source exposure device orientation, a particulate count within the shield, a shock event, or shield wear; a processing system within the housing and configured to store the sensor data and output the sensor data; and a power source within the housing and configured to provide power to the processing system.
