Personal Dosimetry Service
The company is pleased to offer a reliable and responsive personal dosimetry service utilising the latest Electronic Personal Dosimeters. This service is only suitable for users who are not classified persons or as a backup to other HSE approved dosimeters. An Electronic Personal Dosimeter (EPD) will allow the day to day, or even task by task, monitoring of individuals when working with ionising radiations. Depending on your level of usage you may purchase your own EPDs or lease a set of EPDs through the company.

The EPD can measure penetrating external radiation (gamma, x-ray and beta) and is ideal where individual tasks may result in a range of personal doses. In these situations day to day knowledge of doses received is invaluable in ensuring doses are maintained as low as reasonably practicable.

The service that the company can offer includes:

  • Management of client’s own EPDs - including issue, return and routine calibration
  • Lease of the company's EPD to clients where use is infrequent.
  • Management of dose records and provision of routine dose summaries
  • Review of individual doses and advice where doses exceed pre-agreed thresholds
  • Experienced personnel with detailed knowledge of EPD operating systems.
