R-Metrics Ltd. is licensed by the Canadian Nuclear Safety Commission (CNSC) to perform wipe test analysis of sealed radioactive sources.
The CNSC requires that all sealed sources containing 50 MBq (1.35 mCi) or greater of radioactive material be monitored to assess the integrity of the material containing the source. By definition, a sealed source provides a level of assurance that the radioactive material can not escape and result in contamination or an inadvertent exposure. Unfortunately, due to age, use or damage, the integrity of the housing material can be compromised resulting in a potentially serious situation. In evaluating the risk verses the probability of an incident, CNSC has set a graduated leak test frequency schedule taking into account when sources are in storage, incorporated into devices, or in use.
The frequency of leak testing is as follows:
- immediately after an event which may have resulted in the sealed source or shielding being damaged;
- immediately before using a source that had been in storage for a period of 12 consecutive months or greater;
- every 6 months for sealed sources in use and not incorporated into a device;
- every 12 months for sealed sources incorporated into a device;
- every 24 months when a source is in storage.
Most sealed source devices come with their own wipe test procedure. However, if you cannot locate the procedure for your device, R-Metrics Ltd. provides a basic Wipe Test Procedure (click here). Please use the Wipe Test Form from our site for submitting your wipe test samples for analysis.
