Estimation of Effects of Filtration and Ventilation on Worker Inhalation Dose from Aerosols During Nuclear Dismantlement

During the decommissioning of nuclear power plants, radioactive contaminants may be released into the work environment in the form of aerosols, which can expose workers through inhalation, ingestion, and submersion pathways. Workers often perform dismantlement work in confined spaces and sealed-off environments. Typical engineering controls to reduce concentrations include air exchange as well as air […]

RDS-112 Cyclotron Facility Decommissioning

The RDS-112 cyclotron facility, consisting of an 11 MeV self-shielded cyclotron, was located in the McMaster University Medical Centre in Hamilton, ON. This facility was operated from 1990-2018, producing radioisotopes for medical imaging and research; primarily F-18 along with C-11, N-13 and O-15. The McMaster University Health Physics Department provided radiation safety support throughout the lifetime […]

Ionizing radiation exposure effects across multiple generations in non-human biota

The potential for radiation-induced deleterious effects in progeny, and thus, in next generations is a major concern for parents exposed to ionizing radiation from occupational, medical or environmental sources. To date, the systems of radiological protection do not quantify or consider the possibility for effects that may manifest in subsequent generations following the initial exposure. […]
