How do I dispose of x-ray equipment?
Per Health Canada ‘Safety Code 30 – Radiation Protection in Dentistry’ Section B.6.0
When X-ray equipment is considered for disposal, an assessment should be made as to whether the equipment can be refurbished and/or recycled. Communication with the manufacturer or supplier of the equipment should be made as to whether the equipment or components of the equipment can be recycled or returned. Once the decision has been made to dispose of X-ray equipment, an assessment must be made to determine if any equipment components contain hazardous materials.
An assessment should include the following:
- Contact the manufacturer or supplier of the equipment to determine if the equipment or components of the equipment can be recycled or returned.
- If the equipment contains any patient information, this information must be fully removed.
It is strongly recommended that disposal of X-ray equipment be delegated to an X-ray service provider that specializes in the disposal of such systems. Safe work practices during disposal must be used so that workers are not exposed to hazards.
The following disposal actions are recommended:
- The X-ray tube window should be examined to determine whether or not it contains beryllium, and if it does, special disposal procedures must be applied since beryllium presents a toxic ingestion or inhalation hazard;
- The transformer oil must be disposed of in accordance with any applicable federal, provincial or territorial environmental legislation and lead must be recycled accordingly;
- To ensure that the equipment is not unsafely operated after disposal, the equipment must be made inoperable before disposing. The vacuum in the X-ray tube must be breached, and the cables that power the equipment and other electrical connections should be disconnected and disposed of separately.
When should I register radiation equipment?
Registration is required in the following situations:
- Installation of equipment in a new or existing dental facility regardless of how the equipment was obtained (purchased, leased, gift) or how old the equipment is (new or resale).
- Relocation within the facility or to another facility.
- Modification of the characteristics of the radiation emitted from the equipment or the protective properties of the facility. Note: shielding calculations are based in part on the occupancy of adjacent rooms. If a facility is redesigned and the walls are not altered but the occupancy changes (i.e. storage room becomes waiting room), registration of the equipment is still required.
- A full compliance inspection and re-registration of equipment every five years after the original registration of the equipment
How do I register radiation equipment with the CDSA?
To register equipment, submit a completed application for Registration of Designated Radiation Equipment form. The application must be signed by the owner of the facility and a compliance verification report from an Authorized Radiation Protection Agency must be included prior to the clinical use of the radiation equipment.
Who is responsible for ensuring the radiation equipment in dental practices are registered?
The owner of the equipment is responsible for arranging the compliance verification and forwarding the final report to the CDSA along with a completed registration application.
What are the requirements for owning a CBCT machine?
Any regulated member of the CDSA can own CBCT equipment. The owner must have a compliance inspection completed and register the equipment with the CDSA. The owner is also responsible for the proper installation of hardware and software, registration and operation of the unit, including education of the operators, storage of records, and a quality assurance program.
