Calibration of Radiation and Contamination Monitors

Radiation monitoring instruments are required to be properly maintained and tested at appropriate intervals by a 'qualified person' (IRR99 Reg 19). The Approved Code of Practice suggests a test, or calibration, at least every 12 months.

NPL good practice guideWe are qualified to test both radiation survey meters and contamination monitors, providing all the necessary calibration certificates. Instument calibrations are carried out in compliance with NPL Good Practice Guide no. 14 - The Examination, Testing & Calibration of Portable Radiation Protection Instruments. Radman Associates operate a convenient mail-order service ans normally aim to return all radiation instruments within 3 working days.

To check the performance and calibration of your radiation instruments against specific isotopes and energies, please forward them to our calibration department at the address below or call 0845 226 7248 to arrange collection.


Radiation Survey MetersRadiation Survey Meters

Radiation survey instruments are calibrated in our laboratory against a traceable sealed source standard of caesium-137 (gamma rays 662 keV).

Calibration fee: £80 (+ £15 return carriage)


Radioactive contamination monitors
Contamination Monitors

Geiger-Muller probes used for measuring beta contamination on laboratory surfaces are calibrated against wide area reference standards Carbon-14 ( beta 0.16 MeV) and Chlorine-36 (beta 0.71 MeV). Derived responses are given for a surface contamination level of 1 Bq/cm2. Estimated values are provided for the more common inventory of laboratory radioisotopes including Phosphorus-32 (beta 1.71 MeV), Phosphorus-33 (beta 0.25 MeV) and Sulphur-35 (beta 0.16 MeV).

Calibration fee: £80 (+ £15 return carriage)


On-site calibration

If you have a number of contamination instruments it may be more cost-efficient for us to calibrate them on your premises. This will also minimise downtime while instruments are off-site.
