Dosimetry Service Agreement Canada: What you need to know
Dosimetry is the measurement and monitoring of radiation doses received by individuals who work in environments where they may be exposed to ionizing radiation. In Canada, dosimetry services are provided by certified companies that offer different types of dosimeters and reporting options to monitor radiation exposure of workers in various industries. This article will guide you through what you need to know before signing a dosimetry service agreement in Canada.
Types of Dosimeters
Dosimeters are devices that measure the exposure of individuals to ionizing radiation. There are different types of dosimeters used in Canada based on their advantages and disadvantages. The most common types of dosimeters are:
1. Thermoluminescent Dosimeters (TLDs): TLDs are small crystals that when exposed to ionizing radiation store the energy and release it as light when heated. This light is then measured to estimate the radiation dose received by the individual.
2. Optically Stimulated Luminescence Dosimeters (OSLDs): OSLDs use aluminum oxide to measure the radiation dose received by individuals. Similar to TLDs, OSLDs store the energy of the ionizing radiation as light, but they use a laser to read the signal instead of heat.
3. Film badges: Film badges are small plastic holders that contain a small piece of photographic film. When exposed to ionizing radiation, the film changes color, and the degree of color change is used to estimate the radiation dose received.
There are other types of dosimeters that are used less frequently, such as pocket ionization chambers, electronic dosimeters, and personal air sampling equipment. The choice of dosimeter depends on the type of radiation to which the individual is exposed, the level of radiation, and the duration of exposure.
Dosimetry Service Agreement
When choosing a dosimetry service provider in Canada, it’s essential to have a written agreement that outlines the terms and conditions of the service provided. The agreement should specify the type of dosimeter provided, the frequency of monitoring, the reporting format, and the turnaround time for reporting. Other important aspects to consider include:
1. Accreditation: The dosimetry service provider should be accredited by a recognized body, such as the Canadian Nuclear Safety Commission (CNSC), to ensure that they meet quality assurance and standards criteria.
2. Cost: The cost of dosimetry service may vary depending on the type of dosimeter, the frequency of monitoring, the number of employees being monitored, and the reporting format. The agreement should clearly state the cost and any additional fees.
3. Liability: The agreement should specify the liability of the dosimetry service provider in case of any errors or discrepancies in the reported radiation dose. The responsibility of the individual and the employer should also be outlined.
4. Confidentiality: The agreement should clearly state that the dosimetry service provider should maintain the confidentiality of the personal information of individuals being monitored.
Conclusion
Dosimetry is an essential tool in ensuring that individuals who work in environments with ionizing radiation are exposed to safe levels of radiation. When choosing a dosimetry service provider in Canada, it’s essential to select a certified provider and have a written agreement that outlines the terms and conditions of the service provided. By following these guidelines, you can ensure that your employees are effectively monitored and are protected from the harmful effects of radiation exposure.
