The Port Hope Area Initiative (PHAI) is a “mega project” to clean-up low-level radioactive wastes situated in the Municipality of Port Hope and the Municipality of Clarington.  The project involves remediating several contaminated sites to established clean-up criteria and consolidating the wastes in a new engineered mound (one in each community).  The remediation and construction aspects of the project are subject to CNSC licenses and environmental approvals.  The PHAI has a very high public profile and is a top priority for the Government of Canada and the Port Hope area communities.

The project is sponsored by Natural Resources Canada (NRCan), and led by CNL.  The Government of Canada provides oversight for the execution of the project mandate.

The Health Physicist will assist the Health Physics Section Head in providing health physics (HP) and radiation protection (RP) support to the Historic Waste Program (HWP) Management Office as well as, HP consultative advice to CNL and/or contractors, and developing and implementing elements of the project requirements for radiation protection. 

The Health Physicist will perform duties including performing radiological safety assessments; documenting radiological work assessments and assisting in documenting radiological work plans, review of subcontractor RP plans and standard operating procedures, teaching Group 4 RP Training and assisting with the teaching of Group 3 and Group 2 RP Training for CNL staff members and sub-contractors, participating in accident investigations and workplace inspections; advising staff on RP requirements in their respective work areas; performing oversight of the sub-contractor’s execution of their RP Programs, and help to ensure the Port Granby and Port Hope sites, in general, are compliant with the requirements of the PHAI RP Plan and AECL Corporate RP program.

The Health Physicist will also assist the Health Physics, Section Head in creating standard operating procedures which CNL RP and Operations staff will follow during their routine work, to define and present RP Training to CNL staff, and to oversee the dosimetry for CNL personnel.

Technical health physics services for instrumentation and filter counting:

  • Oversight of processes for the calibration of RP instrumentation.
  • Oversight of decontamination methods and techniques.
  • Planning, execution and documentation of scoping, characterization and release radiological surveys.

Other duties may include:

  • Participate in incident response and investigations. 
  • Issue and collect dosimetry (e.g., TLDs, PADs), and send for processing or calibration as required. 
  • Ensure sufficient supply of bioassay collection sample containers for CNL staff.  Supervise the collection, packaging, and shipment of samples to laboratory. 
  • Responsible for meeting HWP quality requirements as defined in the HWP QA Plan and supporting procedural documents in conducting the work.



The position requires a University Degree in health physics or honours degree in science or engineering with post graduate studies and/or experience in health physics or related discipline.  Candidates with >10 years as a Radiation Technician in the nuclear industry will also be considered.

Knowledge, skills and abilities
