The lecture will be a refresher on external dosimetry covering problems of radiation dose calculations from common diagnostic X-ray imaging examinations, reference computational phantoms and uncertainties of reference dose coefficients.
The lecture will be a refresher on internal dosimetry covering problems of modelling doses following inhalation and ingestion of radioisotopes by workers and doses to patients from nuclear medicine procedures.
The lecture will be a refresher on environmental radiological protection covering considerations of environmental protection in the context of ‘sustainable development’ and concerns about the ‘quality of life’, including services provided by the environment and ecosystems.
RBE, Quality Factor, and Radiation Weighting Factor
The lecture will be a refresher on relative biological effectiveness covering problems of estimating radiation weighting factors, low-dose limiting RBEm, dose-response curves for multiple endpoints (cancer, others) and dose-rate effects including DDREF.
Decommissioning Survey Methods Incorporating Scanning Measurement Data
When decommissioning scanning surveys are used in decision making; the uncertainties associated with scanning statistics, and the dominant decay emissions for the survey method(s) must be corrected for.
This PD session will largely focus on scintillation detectors, their optimization, and use in decommissioning surveys. The basic set-up of a gross gamma scintillation ratemeter will be discussed; its uses and applications. A brief refresher on the differences between particle and photon radiation interactions and detection will be presented. The main topic of ratemeter scanning statistics, the two stages of scanning, the application of; source, surface and surveyor efficiencies, and incorporation of all these variables into decommissioning surveys. The variables associated with the two stages of scanning and the concept of minimum detectable count rate will be demonstrated to participants via a dynamic learning exercise (assuming ~1 uCi or greater EQ gamma sources available), participants will need their own mini jack headphones to participate in the execerise as covid-19 precaution.
A summary of the bases documentation in this session will be discussed and the possibilities for further integration into decommissioning practices.
The Importance of Effective Communications during a Radiological Incident
When a radiation incident occurs one of the response challenges is to effectively communicate the situation to varying audiences. Radiation professionals may be called upon to provide information in a variety of ways during and after a radiation emergency. It is often necessary for someone with radiological expertise to assist those individuals/groups forming public messages create a clear and accurate message. The ability to successfully integrate radiation-related expertise into a response and communication scenario requires someone with an ability to break down complicated concepts into an understandable manner for a broad – if sometimes not overly large – audience. Many radiological specialists think that because they are experts on radiation it makes them experts on communications relating to radiation. However, this is oftentimes not the case. It is worth keeping in mind that the techniques that one may use to communicate to the public in the wake of a radiological incident may not be optimal for smaller group discussions. One must remember that responders – be they law enforcement personnel, firefighters, medical care providers, etc. – need to understand the situation they are facing and be confident going forward with their public protection and other response duties.
Radiological assistance, just-in-time training, or assistance with other communication needs may be required. Direct interactions with the victims may be needed. It is possible to envision a multitude of other scenarios where an effective communicator could play an invaluable role in emergency response. Not every radiological incident rises to a level of large-scale interest. Smaller-scale incidents such as an accidental exposure to an orphaned source, isolated contamination events, or even perceived radiation-related events are more frequent and require communications on a more micro level in order to inform victims and those providing assistance.
When speaking to individuals or small groups, one must be able to interpret the audience’s interest and understanding by taking cues from verbal and non-verbal indicators. Effective communication is a skill set developed with years of experience and practice along with a willingness to change one’s approach based on feedback from target audiences. Successful communications can greatly affect the outcome of a variety of radiation emergency situations, so it is important that the proper subject matter experts are identified and integrated into emergency response plans and operations.
Radon is a radioactive gas that is produced naturally from the breakdown of uranium in soil and rock. It is invisible, odourless and tasteless. When radon is released from the ground into the outdoor air, it is diluted and therefore is not a concern. However, in enclosed spaces it can accumulate to high levels and become a health risk. The World Health Organization recognizes radon as a significant cause of lung cancer . In fact, radon is the leading cause of lung cancer in non-smokers.
This session will provide an overview of what radon is, where it is found, why it could be a health risk and what mitigation measures are available to reduce exposure to this gas.
International recommendations for radon from the ICRP and the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) will also be presented.
Furthermore, radon scientists in Canada will present on radon policy in practice, as well as radon measurement data and radon mapping in the province of British Columbia.
Finally, attendees will have the opportunity to participate in a virtual tour of Canada’s first certified radon chamber.

Radiation Protection for Emergencies during the Transport of Radioactive Material
The session will refresh participants on the principles, technical basis, and requirements for emergencies during the transport of nuclear and other radioactive material with an emphasis on the recently published IAEA safety guide Preparedness and Response for a Nuclear or Radiological Emergency Involving the Transport of Radioactive Material.
The session will focus on reviewing the roles and responsibilities of technical experts working with all-hazards emergency response organizations to conduct package assessments and technical response actions
