Portable RPI Calibration and Repair

The JFIMS Radiological Calibration Service calibrates and repairs portable RPI for customers across the UK. The service offers a prompt and reliable service with a rapid turn-round to all customers and complements our on-site calibration service. The service is backed up by a solid quality management system and uses sources traceable to UK national standards. The Radiological Calibration Service is based at Deeside in Cheshire, with good links to the UK national road network. We can arrange the transport of RPI to and from the RCS.

All work is performed by Suitably Qualified & Experienced Persons (SQUEP) and calibration certificates are checked and verified by an experienced Qualified Person (QP). JFIMS meets the statutory requirements of the Ionising Radiation Regulations 1999 (IRR99) by following the guidance given in NPL Measurement Good Practice Guide No. 14; "The Examination, Testing, & Calibration of Portable Radiation Protection Instruments" (GPG14).
We deliver a cost-effective service including tests before first use, full instrumentation checks, performance checks, repairs, adjustments and test before 'return to service' on instruments from all major RPI suppliers to the UK nuclear industry. Repairs are only carried out after your acceptance of our written quotation.
All work is carried out to a comprehensive set of maintenance and test procedures approved by an experienced senior qualified person.
Calibrations can be scheduled to ensure customers retain sufficient stock of RPI for on-going operations.
All RCS activities will meet the requirements of quality management system BS EN ISO 9001:2000.
The RCS is accredited to BS EN ISO 17025:2005 as calibration laboratory 4382.

Gamma dose rate

We can measure air kerma rate, ambient dose equivalent (H*(10)) and personal dose equivalent (Hp(10)) for the assessment of the radiometric performance of a wide range of gamma monitors, dose rate meters and personal alarming dosimeters and other RPI in our purpose-built gamma cell.

Surface contamination monitors

We have a range of large-area alpha and beta sources for the calibration of surface contamination monitors providing alpha and beta radiation of both low and medium energies. The surface emission rates are traceable to national standards. Sources are Class 2 reference sources manufactured to the standards set in ISO 8769.

Repair facility

We have experienced staff and a well-equipped repair workshop backed up with manuals and stock of key spares from all major UK suppliers of RPI to minimise turn-round times for faulty or damaged instruments. Repair work is only undertaken after you have accepted our written quotation. The instrument is then fully checked and calibrated prior to being returned for use.
