Whenever an individual comes into contact with a radioactive material the possibility exists that they will absorb, inhale or ingest some of it and that radioactivity will enter their body. Understanding the isotopic profile and the quantity of radioactivity retained in the human body after an uptake event is important for dose management. This uptake can be measured in two ways; by directly monitoring the body, or by analysis of bodily fluids.

Bioassay services are used for ongoing confirmatory monitoring programs and as a one-off to respond to an emergency uptake event.

We offer complete dosimetry services involving the measurement of key alpha, beta, and gamma radioisotopes in urine, feces, and nasal swabs.

Why Us?

  • Rapid Response

    When personal health and safety are at stake, such as in a suspected uptake event, you may need to obtain information quickly. We have the ability to mobilize a rapid response service and quickly get you the answers you need.

  • Licensed and Accredited

    Our alpha dosimetry Lab is licensed by our nuclear regulator according to S-106, "Technical and Quality Assurance Requirements for Dosimetry Services", and our testing procedures are accredited to ISO 17025 by the Standards Council of Canada.

  • Dose Assessment and Supporting Services

    In addition to performing the analyses, our certified health physicists will calculate the dose, advise on any necessary actions, and help you with your investigations.

  • Femtogram Detection Limits

    Our sector field inductively coupled plasma mass spectrometry (SF ICP-MS) plutonium analysis has femtogram detection limits for Pu-239 and Pu-240 in urine bioassays.
