X-ray Safety

X-rays are used across Ryerson University for both research and teaching applications. Ryerson’s X-ray Safety Program, administered by the Environmental Health and Safety (EHS) radiation safety officer, is designed to assist all users of X-ray sources in meeting the legislative requirements and to protect students, faculty, staff and visitors from damaging exposure. The PDF fileX-ray Safety Program Manual outlines the requirements and procedures established by the university for work with X-rays.

Getting started

Applying for a permit

All work conducted by university members with X-ray sources on university premises or under the control of the university requires an X-ray Safety Permit.

Researchers and lab managers requiring a permit should complete an X-ray Safety Permit application.

Once you have applied for a permit, contact the radiation safety officer so they can conduct a risk assessment. Get in touch at ehs@ryerson.ca or 416-979-5000, ext. 554212.

Training

Training is a key component of the X-ray Safety Program and is mandatory for all users working with X-rays to complete prior to the start of work. Users are expected to study the modules below and successfully pass the X-ray quiz, administered by EHS. A certificate is granted after the successful completion of the quiz.

Step 1: Download the slides and study the content

The goal of these slides is to walk the user through an understanding of university policy and safety procedures when working with analytical X-ray devices. The training covers basic health and safety principles to help the user minimize their exposure to the harmful effects of X-rays by controlling the associated hazards.

Step 2: Complete the quiz

Following the study of the above content, you will have to complete the X-ray safety quiz, administered by EHS. To arrange an appointment, contact EHS at ehs@ryerson.ca or 416-979-5000, ext. 553770.

Setting up your lab to work with X-ray systems

From obtaining X-ray equipment to registering with the Ontario Ministry of Labour, setting up your lab is an important process in making sure proper controls are in place to provide for a safe working and teaching environment. The EHS team can support you through this process. Please notify the radiation safety officer at 416-979-5000, ext. 554212 or ehs@ryerson.ca of your intent to obtain an X-ray device as soon as possible.

Registration and inventory

All X-ray systems not regulated by the Canadian Nuclear Safety Commission must be registered with the Ontario Ministry of Labour prior to use, and this registration must be amended should the unit be moved or disposed of. To register your X-ray device, contact the radiation safety officer at ehs@ryerson.ca or 416-979-5000, ext. 554212.

Getting a thermoluminescent dosimeter (TLDs)

Thermoluminescent dosimeters (TLDs), also known as personal dosimeters or radiation badges, monitor an individual's exposure to ionizing radiation. Some X-ray users will require a radiation badge depending on the type of X-ray device being used. X-ray users should contact the radiation safety officer at ehs@ryerson.ca or 416-979-5000, ext. 554212 for an assessment of their work before applying for a radiation badge.
