The prospective for radiological sustainability through the reuse of NORM residues in construction materials
Terrestrial materials contain naturally occurring radionuclides, including U-238, Ra-226, Th-232, and K-40, are important for radiation protection. Such naturally occurring radioactive material (NORM) residues are produced in large quantities and would be of high economic benefit if they were to a certain extent incorporated in mixtures or as additive in building material production, allowing for […]
Radiation Safety Improvements for a New Self-Contained High Dose Rate Research Irradiator
Current best practices for industrial applications of radiation technology needing high dose rates embrace utilizing self-contained research irradiators for application specific irradiation. Although a stable mainstay of radiation testing campaigns for many decades, the Gammacell 220 has inherent external radiation leakage that contributes to worker dose. The model GR420 by Hopewell Designs is intended to […]
From Medical Physics to Health Physics: Navigating a Career Shift Across Borders
Transitioning careers across countries is never easy, especially in a specialized field like radiation protection. In this presentation, I will share my personal journey from working as a Radiation Safety Officer (RSO) in Brazil’s healthcare sector to establishing a career in health physics in Canada. Arriving in Canada, I faced challenges common to many internationally […]
Partnership in Preparation: Strengthening Radiological Response Capabilities Through Collaboration with Community Partners
Emergency Preparedness and planning for radiological emergencies can be challenging. This session will introduce tools and strategies for mitigating the impact of these obstacles. As part of these strategies, insight into how community partnerships can strengthen response capabilities and overcome these challenges will be proposed. The mutually beneficial relationships developed between the City of Hamilton […]
Yeast-Based Impedance Biodosimetry for Retrospective Assessment of Radiation Exposures
Saccharomyces cerevisiae yeast cells were investigated as fortuitous dosimeters for retrospective assessments of exposures following large-scale radiological or nuclear accidents. The radiation response of yeast cells was examined by using cellular metabolic activity and electrical impedance of the solution to evaluate dose. Active laboratory-grade dry yeast cells were used as the biological material as these […]
A Series of Unfortunate Events – Decontructing the Requirements for Reporting on Norm Related Incidents
Norm related materials and events associated with these materials have ‘normally’ fostered confusion on their oversight within the NSC Act and Regs. In light of the resurgence of interest for safeguards reporting, this presentation will review an incident that highlighted the need to understand the use of dosimetry for personnel exposure to radiation emitting devices […]
Radiation Protection Programs for Security Scanners using Ionizing Radiation
Technology is rapidly outpacing the creation of regulations in the area of security scanners utilizing ionizing radiation. The previous presentation discussed various types of such scanners, including systems designed specifically for screening of humans and systems designed for screening of vehicles or cargo containers which may contain humans (the driver or a stowaway). In this […]
Canadian and International Requirements for Security Scanners using Ionizing Radiation
Technology is rapidly outpacing the creation of regulations in the area of security scanners utilizing ionizing radiation. There are various types of scanners that utilize ionizing radiation, including systems designed specifically for screening of humans and systems designed for screening of vehicles or cargo containers which may contain humans (the driver or a stowaway). There […]
Shaping the Future of Health Physics: Innovations, Challenges, and Opportunities in Radiological Protection
This research provides an in-depth exploration of the future trajectory of health physics, considering both external and internal factors shaping its development. Externally, the presentation examines the challenges and priorities associated with measuring low-dose radiation (10–100 mSv) and highlights the transformative potential of biomarkers in understanding radiation susceptibility from low-dose exposures. Emerging technologies, such as […]
Quantifying Isotope Activities Using a Gamma Spectrometer Survey Meter
During the operation of high energy accelerators, activated materials are commonly created. The activity and isotopes present in these materials must be characterised for their clearance and release from the facility, or to ascertain their duration of stay in a radiological storage area. An activity estimate method using a gamma spectrum collecting survey meter is […]
