A Novel Anthropometric Phantom for Rapid Radiological Triage: A Quick Sort Triage Solution.

Rapidly identifying individuals who have received internal radiation exposure above action guidelines is crucial for mitigating health risks and addressing public concerns immediately following a radiological event involving the dispersal of radioactive materials. This study describes a novel triage method using a conventional Geiger-Mueller (GM) detector to select those individuals from the large group of persons who may have received an intake of radioactive material at levels corresponding to one Clinical Decision Guide (CDG). The triage method involves placing a portable GM detector against the lower anterior torso of a sitting person as they bend over to surround the detector with their body.

Reconstructing a chronic, malunited Galeazzi fracture with distal radial ulnar joint instability: a simple, modified technique.

A male in his 70s presented with a chronic malunited comminuted Galeazzi fracture dislocation, including angular malunion, radial shortening (1.3 cm ulnar-plus variance) and distal radioulnar joint (DRUJ) instability secondary to chronic dislocation with mechanical rotation block. A modified, single-stage radius corrective osteotomy with bone grafting technique to overcorrect radius length was employed, restoring normal DRUJ motion and stability by engaging the secondary DRUJ stabilisers without triangular fibrocartilage complex repair.

A METHOD TO IDENTIFY AND LOCALIZE A SINGLE HOT PARTICLE IN THE LUNGS USING AN ARRAY OF HIGH-PURITY GERMANIUM DETECTORS FOR IMPROVED ESTIMATE OF THE DEPOSITED ACTIVITY.

A new method has been developed to identify and localize a single hot particle in the lungs using an array of four high-purity germanium detectors. The method is based upon calculating a set of three count rate ratios (generated by each individual detector in the array) that are evaluated in sequence to designate whether the measured deposition can be associated with a hot particle rather than the default assumption of a uniform activity distribution. Identification and localization of the hot particle are determined from a single in vivo measurement in which detectors are positioned above and below the thorax.

Antiandrogen Therapy Radiosensitizes Androgen Receptor-Positive Cancers to F-FDG.

A subset (35%) of triple-negative breast cancers (TNBCs) expresses androgen receptor (AR) activity. However, clinical trials with antiandrogen drugs have shown limited efficacy, with about a 19% clinical benefit rate. We investigated the therapeutic enhancement of antiandrogens as radiosensitizers in combination with F-FDG in TNBC.

MEASUREMENT AND ANALYSIS OF THE NEUTRON ENERGY SPECTRUM AND ASSOCIATED OCCUPATIONAL EXPOSURE FROM A SHIELDED241AM-BE SOURCE.

A set of five Bonner spheres was used to measure the ambient neutron H*(10) dose around an orphan 241Am-Be neutron source shielded with different arrangements and types of neutron-absorbing materials. These results were compared to measurements obtained using a portable radiation dosemeter. The Bonner sphere measurement results identified the presence of a large thermal and intermediate neutron component from the shielded 241Am-Be source that was not revealed using the portable instrument.
