Selection of a New Dosimetry System: One Utility's Experience
Ontario Hydro is an electrical utility that operates 20 nuclear reactors of the Candu design. Dosimetry for workers is provided by an in-house thermoluminescence dosimetry service, using two-element dosemeters designed by Atomic Energy of Canada Limited in the late 1960's. Several recent assessments of the dosimetry system have recommended that it be replaced with more up-to-date technology. There has also been much interest within the company in the possibility of adopting electronic dosemeters for dosimetry of record. The task of evaluating alternative technologies and recommending the best option for the next dosimetry system was assigned to a team of employees. This team had representation from all of the four nuclear stations, from the two dosimetry laboratories, from the two major labour unions and from the purchasing department. Broad representation was considered necessary to ensure that the interests of all concerned parties would be taken into account. However, the team approach to making such recommendations appears to be uncommon, perhaps even unique. This paper describes the process that was followed by the team and its outcome.
