Radiation Dose and Risk in the Radiological Investigation of Suspected Non‐Accidental Injury (NAI)

Journal of Medical Radiation Sciences, EarlyView.
This study is a retrospective analysis of 362 skeletal surveys performed over a 5‐year period for children under 5 years of age for suspected non‐accidental injury. We present effective dose data and the associated risks of radiation exposure for initial and follow‐up examinations.

Recent Advances in Hydrogel-Based Sensors Responding to Ionizing Radiation

Gels, 2022
Ionizing radiation and its applications are widely spread throughout life. Similar to many other things, both the positive and negative aspects of ionizing radiation should always be kept in mind.

Advanced dosimetry systems for the space transport and space station [PDF]

, 1972
Advanced dosimetry system concepts are described that will provide automated and instantaneous measurement of dose and particle spectra. Systems are proposed for measuring dose rate from cosmic radiation background to greater than 3600 rads/hr.

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy

A hybrid radiation detector for simultaneous spatial and temporal dosimetry [PDF]

, 2011
In this feasibility study an organic plastic scintillator is calibrated against ionisation chamber measurements and then embedded in a polymer gel dosimeter to obtain a quasi-4D experimental measurement of a radiation field.

Your C‐Arm May Be Dose Optimised but Is Your Surgical Procedure? The Evaluation and Dose Optimisation of Positioning Aids Used in Paediatric Image Guided Surgery

Journal of Medical Radiation Sciences, EarlyView.
This study objectively evaluated the impact of positioning aids on radiation dose and image quality (IQ) in paediatric image guided surgery (IGS) and the potential for dose optimised imaging via the choice of positioning aid type selected for clinical use.

Effect of gamma irradiation and storage days on physicochemical, sensory, and microbial quality of pineapple (Ananas comosus) fresh cut under refrigeration

JSFA reports, EarlyView.
Abstract Background Fresh‐cut pineapple is increasingly consumed for its convenience and nutritional value; however, minimal processing accelerates quality deterioration and microbial growth, resulting in substantial postharvest losses. Gamma irradiation is recognized as a nonthermal preservation technique, but limited information exists regarding its ...

One‐year follow‐up after fractionated ultra‐high‐dose‐rate FLASH radiotherapy in patient with extramammary Paget disease of the scrotum

Precision Radiation Oncology, EarlyView.
An elderly male patient with extramammary Paget disease of the scrotum and multiple metastases was treated with fractionated FLASH‐RT (40 Gy in 5 fractions) in the scrotal lesion. Abstract Objective Ultrahigh‐dose‐rate radiotherapy (FLASH‐RT) has been shown to reduce radiation‐induced normal tissue injury in preclinical studies.
