Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Radiation Safety Policy

Classification number LCG 1148
Framework category Legal, Compliance and Governance
Approving authority Board of Governors
Policy owner Vice-president responsible for Research
Approval date April 22, 2021
Review date April 2024

Purpose

This policy sets out the standards, requirements and responsibilities that apply to research and scholarly activities involving ionizing and non-ionizing radiation, including nuclear substances and radiation emitting devices at the University of Ontario Institute of Technology (Ontario Tech).

Definitions

For the purposes of this Policy the following definitions apply: 

“Action Level” means a specific dose or other parameter that, if exceeded, may indicate a loss of control of part of the radiation safety program. 

“Authorized Users” means any University Member who has been authorized to handle ionizing or non-ionizing radiation in accordance with the requirements set out in the Radiation Safety Program. 

“ALARA” (as low as reasonably achievable) means an optimization tool in radiation protection used to keep individual, workplace and public dose limits as low as reasonably achievable, social and economic factors being taken into account. ALARA is not a dose limit; it is a practice that aims to keep dose levels as far as possible below regulatory limits. (ALARA) 

“CNSC” means the Canadian Nuclear Safety Commission, the federal regulatory agency whose mandate is to establish and enforce the Nuclear Safety and Control Act and Regulations. The CNSC regulates the use of nuclear energy and materials to protect health, safety, security and the environment, and to implement Canada's international commitments on the peaceful use of nuclear energy.

“Ionizing Radiation” means particles, X-rays, or gamma rays with sufficient energy to cause ionization in the medium through which it passes.

“MOL” means the Ontario Ministry of Labour, the provincial regulatory agency whose mandate is to establish and enforce the Occupational Health and Safety Act, which includes the X-ray Safety regulation and takes into consideration the American National Standards Institute (ANSI) Z136 series of laser safety standards (the “ANSI” Standards).

“Non-Ionizing Radiation” means any type of electromagnetic radiation that does not carry enough energy to ionize atoms or molecules.

"Nuclear Substance” means:

  1. deuterium, thorium, uranium or an element with an atomic number greater than 92; 
  2. a derivative or compound of deuterium, thorium, uranium or of an element with an atomic number greater than 92;
  3. a radioactive nuclide;
  4. a substance that is prescribed as being capable of releasing nuclear energy or as being required for the production or use of nuclear energy;
  5. a radioactive by-product of the development, production or use of nuclear energy; and
  6. a radioactive substance or radioactive thing that was used for the development or production, or in connection with the use, of nuclear energy.

“Radiation” means, for the purpose of this policy:

  1. energy in the form of electromagnetic waves or acoustical waves with the potential to harm;
  2. the emission by a nuclear substance, the production using a nuclear substance, or the production at a nuclear facility of an atomic or subatomic particle or electromagnetic wave with sufficient energy for ionization.
“Radiation device” means any device that contains more than the exemption quantity of a nuclear substance and that enables the nuclear substance to be used for its radiation properties.

“Radiation emitting device” means any device that is capable of producing and emitting radiation.

“Radioisotope Laboratory” means a conventional laboratory that is permitted to house radioactive materials and all activates within the laboratory are prescribed by a radioisotope permit.

“Radiation Safety Program” means the documented policies and procedures developed to control the risks and hazards associated with ionizing and non-ionizing radiation. The radiation safety program includes x-ray safety and for the purposes of this policy includes the laser safety program. These programs are documented as the Radiation Safety Manual and the Laser Safety Manual and outline the university’s responsibility and oversight for the protection of personnel
against the harmful effects of radiation.

“University Member” means any member of the Ontario Tech community who teaches, conducts research or works at or under the auspices of the University and includes any of the following:

  • A person who is an employee of the university;
  • Any person who is an appointee (including adjunct faculty, emeritus, a volunteer on research related committees and boards) of the University , or
  • Student, post-doctoral fellows, visiting scholars, contractors, and any other research personnel while they are engaged in research or scholarly activities under supervision of a Member.

 

Scope and authority

This policy applies to all activities at the University involving ionizing and non-ionizing radiation and radiation emitting devices defined under this Policy.
The Vice-President Research and Innovation, or successor thereof, is the Policy Owner and is responsible for overseeing the implementation, administration and interpretation of this Policy.
On behalf of the Vice-President, Research and Innovation, the Radiation Safety Officer and the Radiation Safety Committee have the authority to immediately stop any use of ionizing and nonionizing radiation sources and radiation emitting devices which deviates from the approved conditions set out in a Permit or is deemed to be in non-compliance with the applicable legislation and regulations and/or university policy or procedures as described under the Radiation Safety Program.

Policy

The University is committed to protecting all University Members and the environment from any adverse effects resulting from the use of ionizing and non-ionizing radiation for research and scholarly activities at the University. To this end, the University will maintain a radiation safety program to ensure the safe use, storage, transfer and disposal of radiation and radioactive materials in compliance with all legislated requirements, University Policies and Procedures.
