====How can CNSC staff members suggest improvements to the laboratory?====

Through annual customer satisfaction surveys that the CNSC laboratory conducts, CNSC staff members who have used the laboratory services in the previous year can provide feedback on their quality, including suggestions for improvement. The CNSC laboratory has been conducting such surveys since 2015, and has taken action to address comments from its customers to meet its commitment to provide a high service level and meet customer expectations. One such action was to respond to the suggestion to provide links to instrument manuals from the laboratory’s Web page.

The CNSC laboratory gamma calibration service now operates within a quality management system that complies with the requirements of [https://www.iso.org/standard/39883.html ISO/IEC 17025:2005]. As specified in the quality management system, the laboratory implements mechanisms including, but not limited to, proficiency testing, customer satisfaction surveys, internal reviews, management reviews, and corrective and preventative actions to drive continual improvement, which is the true intention of the ISO/IEC standard.

=='''1.1''' '''Customer Feedback'''==

The CNSC Laboratory solicits customer feedback on an annual basis as one of the measurements of performance of the Laboratory Management System (LMS) ([Pcdocs://E-DOCS/4412335/R e-Docs-#4412335]) in regards to instrument management and calibration services. Customers can provide feedback to the Laboratory to address any issues which require immediate attention any time as needed, however, the annual survey provides an opportunity for customers to feedback on any aspect of the laboratory’s services including data quality and turnaround times. Any immediate problems as reported by the customers are to be documented and corrected through the non-conformance and corrective action processes following the Laboratory procedure P409 ''Corrective Action and Preventive Action'' in a timely manner by the Management System Officer (MSO).

Customer feedback is solicited to conform with the requirements of standards ISO/IEC 17025:2017, “General Requirements for the Competence and Testing of Calibration Laboratories”, and “SCC Requirements and Guidance for the Accreditation of Testing Laboratories – April 2018.”

The survey was executed during the spring and summer in 2018. All customers who were identified as requestors of instrument services during the calendar year 2018 were contacted via Microsoft® Outlook email with a formal invitation for their participation in the survey. Customers were given the choice to describe the impression of services as Excellent, Good, Fair or No Impression using the Voting button as well as an option to include any comments a customer may wish to have for the improvement of services.

A telephone call/voice message was used to remind the customer within few days after the initiation of the survey. Those customers who did not respond within few weeks of the initial formal request for participation were sent the reminder email in late summer same year.

===3.3.1 Customer Response to the Survey ===

Table 1 illustrates the proportion of customers who responded to the survey. The total cohort response yielded 43 responses and 8 non-responses, of possible 51 responses, for a final customer response rate of 84%. Out of 60 customers who were originally identified to seek feedback, 9 of them were not available to respond either because they were no longer working for CNSC or on extended leave. This response rate was relatively higher than that of previous surveys conducted for calendar years 2014, 2015, 2016, and 2017, as illustrated in Table 2. It also demonstrates an increasing trend since the inception of survey in 2014 as demonstrated in Figure 1. This increased participation in the survey could be apparently attributed to number of factors including the simplified form used this year as well as follow up phone calls/voice messages given to customers after initiating the survey.

The accuracy of dosimetry for radiation therapy and radiation safety is vital. Accuracy of radiation dosimetry depends on the quality of calibration of the device used to quantify the radiation dose. Calibration of such an equipment can be performed in two types of laboratories: primary standard lab also which mostly are commonly called national meteorological institute in the country or at a secondary standard laboratory. A primary laboratory maintains the [[wikipedia:Standard_(metrology)|primary standard for measurement]] of ionizing radiation in SI units which is compared and calibrated with the standard maintained in [[wikipedia:International_Bureau_of_Weights_and_Measures|International Bureau of Weights and Measures (BIPM)]] whereas the secondary lab maintains the standard which is used to calibrate dosimeters and survey meters which is traceable one of the NIMs. In Canada, the [https://nrc.canada.ca/en/certifications-evaluations-standards/instrument-calibration-services/ionizing-radiation-standards-calibration-services NRC MSS] maintains primary standards for ionizing radiation.

By becoming a member of the network of SSDL, CNSC~~ is reaffirming its commitment as through ISO/IEC 17025 accreditation to continue to maintain the traceability of standards as a secondary standard laboratory and continue to provide services with the required accuracy and precision to clients within CNSC and counterpart institutions within federal and provincial governments with MOUs which meets the accuracy, ~~precision~~ and ~~traceability requirements~~. ~~Membership of~~ the ~~network is aligned with CNSC priorities as Modern~~, ~~trusted, global and agile~~ {| class="wikitable" |'''~~CNSC Priority~~''' |'''~~Description on CNSC Laboratory alignment with the priority~~''' |- ~~| Modern | Adopting latest standards ISO/IEC 17025 for Laboratory management~~ for ~~calibration services and recognition with IAEA as a secondary standard lab to promote accuracy, traceability of ionizing radiation in SI units |~~- | ~~Trusted | Recognition by national institutes such as standards council of Canada and NRC MSS as an ISO/IEC 17025 accredited lab and recently by IAEA as a full member of the network~~ |- | ~~Global | Participate in global network of SSDLs~~ to ~~aimed to improve~~ the ~~accuracy of radiation dosimetry and to support network members globally through IAEA |~~- | ~~Agile~~ | ~~Continue to evolve and grow to meet demands of current and future needs.

Every developed country in~~ the ~~world has~~ a ~~primary laboratory~~ and ~~one or more Secondary standards laboratories~~ to ~~support calibration requirements~~. ~~As an SSDL, CNSC~~ is in ~~a position to support and serve other network members as well as within TerraCanada and clients as per scope of accreditation~~. '''~~How does it benefit the network?~~''' ~~Over several decades, the CNSC laboratory has a long history of providing equipment management and calibration services to clients within CNSC and other federal and provincial government departments~~. Over the years, CNSC has made huge strides toward developing a management system that fully complies with the stringent requirements of ISO/IEC 17025, introducing efficiencies through machine vision systems, automated data collection, data analysis tools with automated functionality to minimise human errors due to task repeatability, compliant Excel spreadsheets, and other management tools. Design of protocols for PT for dosimetry, which are practical to implement for relatively small laboratories is quite challenging. There are no such protocols exist and hard to conceive because of challenges for calibration laboratories. CNSC has experience in designing and implementing of such protocols. =
