The use of dental radiographs is an important component of dental hgyiene practice. These resources will inform your practice.

Under the Health Professions Act, dental hygienists can provide their services in a wide variety of settings. Settings and practice models include independent dental hygiene practice and practice in association with another person or another regulated health professional. Further, dental hygienists may own and operate ionizing and non-ionizing radiation equipment including dental x-ray equipment and lasers used for periodontal therapies or bleaching procedures. 

Radiation Protection Act

Pursuant to Radiation Protection Act Internal Link , all dental x-ray equipment including digital radiography systems, Class 3B lasers (i.e., Periowave Laser Base Station PW1100) and Class 4 lasers, are designated as radiation equipment that must be registered prior to use.

The purpose of the Radiation Protection Act is to ensure protection of: 
5(1)  Every person owning, installing, supplying, operating or servicing a radiation facility, radiation equipment or radiation source shall take all reasonable precautions to protect persons from radiation injury.
(2)  Every worker employed in connection with a radiation facility or a business or undertaking involving the use of radiation shall:

  • take all reasonable precautions to ensure the worker's own safety and the safety of fellow workers, and
  • use the protective devices and equipment and wear the protective clothing provided by the employer.


Radiation Protection Regulation

The intent of Radiation Protection Regulation Internal Link is to protect workers and members of the public from excess exposure to ionizing radiation and to non-ionizing radiation from higher-powered lasers. The Regulation specifies maximum exposure limits and the monitoring of personal exposure to ionizing radiation. It lists designated radiation equipment that requires a registration certificate, and outlines the conditions for issuing these certificates.


Alberta Association for Safety Partnerships

Alberta Association for Safety Partnerships Internal Link (AASP) is the authorized Radiation Health Administrative Organization designated to ensure that dental hygiene owners of radiation equipment are in compliance with the Radiation Protection Act and Regulation. If you have made arrangements to purchase or acquire radiation equipment for use in your dental hygiene practice, please visit the AASP website at to download all documents related to registration, inspection and monito

Failure to be in possession of a valid registration certificate from the AASP prior to the operation of your radiation equipment is a contravention of the Radiation Protection Act. In accordance with the Act, the penalty for this offence is a maximum fine of $15,000 and/or six months imprisonment. Operation of unregistered radiation equipment would also be considered unprofessional conduct under the Health Professions Act. Radiation equipment must not be operated until it has been inspected and registered with the AASP.


Safety Code 30

Safety Code 30 Internal Link provides specific guidance to the dentist, dental hygienist, dental assistant, and other support personnel concerned with safety procedures and equipment performance.

This document is one of a series of safety codes prepared by the Radiation Protection Bureau to set out requirements for the safe use of radiation-emitting equipment.
