Hydrophones for ultrasonics calibration

NPL offers UKAS accredited and ISO 17025 compliant calibration of free-field sensitivity of hydrophones used to characterise medical ultrasonic fields.

Therapy level photon calibration

We provide traceable calibration of a therapy-level dosimeter for linac photon beam, using a cobalt reference.

Therapy level electron calibration

NPL provides traceable calibration of therapy-level dosimeter for Linac Electron beam.

Electrometer calibration

Our electrometers help to read data from ion chambers with a calibration uncertainty of ± 0.2 %.  

Radiotherapy dosimetry audits

NPL offers a wide range of reference and end-to-end dosimetry audits for advanced radiotherapy.  

Brachytherapy  calibration

We can provide calibration for ¹⁹²Ir high dose rate (HDR) brachytherapy dosemeters, used as secondary standards or for instruments required for accurate measurements.  

Protection level air karma

We offer a calibration service of ion chambers for lower dose rate radiation.

Diagnostic and mammographic x-ray dosemeters

NPL provides diagnostics for ion chambers and mammographic calibration services in accordance with BS IEC 61267:2006 for Medical Diagnostic X-ray Equipment.

Ophthalmic applicator calibration

Calibration services for Ru-106 and Sr-90 curved and planar ophthalmic applicators with an uncertainty of ± 7 % (k=2).

Standardised radionuclide - calibration and supply

We provide calibration of pure-β, α, β/γ emitting radionuclides for nuclear medicine. 

Custom radionuclide - calibration and supply

The nuclear metrology group at NPL can supply custom made standards for a wide range of radionuclides and activity concentrations.  

Fidelis secondary standard radionuclide calibrator

Our ionisation chamber provides rapid access to traceable measurements for a wide range of medical and industrial radionuclides.

Environmental proficiency test exercise

We provide traceable proficiency assessment to test, validate and compare your laboratory’s performance in carrying out measurements.

Practical course in reference dosimetry

This blended learning course will develop a fundamental, theoretical and practical understanding of all aspects of reference dosimetry and familiarise learners with UK primary standards & codes of practice.

Radionuclide calibrator course

This 2-day e-learning course will help hospitals to maximise accuracy of activity measurements, help them to meet nuclear medicine competencies and improve quality assurance processes.

Radionuclidic impurity checks

Within this UKAS accredited testing, fluorine-18 is attached to glucose molecules which, once in the body, are absorbed by tumours and used for cancer imaging.
