Oral and maxillofacial diagnostic imaging is of paramount importance in dental clinical diagnosis, treatment planning, and follow-up procedures. Periapical radiographic examination and numerous panoramic systems are used in routine clinical dental practice. Cone beam CT is widely used and currently the method of choice in oral and maxillofacial implantology, endodontics, maxillofacial surgery, periodontics, degenerative temporomandibular joint disease, orthodontics, airway studies, sleep disorders, and forensic dentistry.

Environmental pollution associated with long term effects, especially in the case of ionizing radiation, poses significant risks to wildlife, necessitating a more nuanced approach to Ecological Risk Assessment (ERA). In radioecology, current methods, as outlined by the International Commission on Radiological Protection (ICRP), focus primarily on exposure and individual/population-level effects, often both suffering a lack of ecological realism due to the nature of data used, and, sidelining a big amount of critical non-individual effects such as sub-individual one like genotoxicity. This review aims to address these gaps by suggesting the integration of New Approach Methods (NAMs) and the Adverse Outcome Pathway (AOP) framework in the field of radioecology.

Controlling the absorbed dose received by a target is a major challenge encountered during ionizing radiation applications. For experimentally measuring absorbed dose, dosimetric systems are used. On the other hand, in addition to experimental methods of dose measurement, there are other alternatives for calculating absorbed doses, these are numerical methods based on the Monte Carlo method which are very sophisticated and widely used throughout the world.

Department of Radiography, Faculty of Health Science, Durban University of Technology, Durban, South Africa.
Background: The consequence of non-compliance with patient radiation safety standards increases unnecessary radiation exposure with high chances of harmful biological effects. Radiographers are trained to prevent these harmful effects by enforcing radiation protection, which is achieved through proper techniques, equipment, shielding materials and beam collimation.
Aim: The study aimed to explore compliance with radiation protection by radiographers in Eswatini public health facilities (PHFs).

Radiation therapy is a common cancer treatment but often damages surrounding healthy tissues, leading to unwanted side effects. Despite technological advancements aimed at improving targeting, minimizing exposure to normal cells remains a major challenge. High-Z nanoparticles, such as gold nanoparticles (AuNPs), are being explored as nano-radiosensitizers to enhance cancer treatment through physical, biological, and chemical mechanisms.
