Products & ServicesWe provide world-class research, calibrations, specialised measurement services and training for the dosimetry of ionising radiation in cancer therapy, diagnostics and industrial sterilisation for medicine and pharmaceutics.
Healthcare
- NPL operates a mailed alanine reference dosimetry service for 60Co γ-ray and megavoltage photon beams.
- NPL now offer dosimetry audits for non-reference conditions, including IMRT, rotational therapy, SABR/SBRT and FFF.
- NPL audit services for therapy level MV photons, electrons and medium energy X-rays are available by arrangement.
- Linac commissioning is a time-consuming process. NPL now offers support in the form of staff time and equipment to assist in the beam data acquisition part of commissioning.
- NPL's diagnostic and mammographic calibration service is for ionisation chambers to be used intentionally as secondary standards or instruments required for measurement of the greatest accuracy.
- Calibration of an ionisation chamber in terms of absorbed dose to water, based on primary standard electron-beam graphite calorimeter. Available in Spring each year.
- Calibration Service for 192Ir High Dose Rate (HDR) Brachytherapy Dosemeters.
- Calibration of non-invasive voltage measurement equipment (kV meters), traceable to standards of electrical potential.
- A calibration service for ophthalmic applicators has been developed by NPL's Radiation Dosimetry team.
- Traceable calibration of a therapy-level dosemeter in terms of absorbed dose to water or air kerma. The service is available for thimble chambers or thin-window chambers, and offered in spring of each year.
- A calibration service for electrometers for use with secondary standard ionisation chambers is available on demand.
Industrial Dosimetry
- Chemical dosimetry involves determination of dose by the measurement of chemical changes induced in materials by ionising radiation.
- Links to all aspects of our chemical dosimetry measurement services and other useful information.
- NPL alanine dosimeters, specifically designed for 1 MeV to 4 MeV industrial electron beams, are available pre-packaged in convenient holders.
- NPL delivers traceable dosimetry to your irradiation plant with a fast reliable mail-order service available on demand.
Ionising Radiation Modelling
NPL offers consultancies, collaborations and training, based on our scientists' wealth of experience in Monte Carlo radiation modelling and other modelling techniques.
Radiation Protection
- Regulatory agencies, local authority monitoring laboratories and the nuclear industry all require accurate, well calibrated instruments in order to monitor environmental dose rates at successively lower levels.
- NPL's protection-level calibration service is tailored for ionisation chambers used as secondary standards or instruments required for measurement of the greatest accuracy.
Training
- Details of Monte Carlo meetings and workshops
- This course is primarily aimed at trainee radiotherapy physicists but would also benefit anyone wishing to improve their practical dosimetry techniques.
Facility Hire
- NPL's three Co-60 self-shielded irradiators are available for the irradiation of dosimeters or investigations, and tests of materials. The irradiators provide Co-60 gamma-ray fields covering dose rates from 0.4 Gy/min to 225 Gy/min.
- The protection level gamma-ray facility at NPL has a multi-source, collimated irradiator situated in a large electrically screened, temperature-controlled exposure room.
- A therapy level Co-60 Gamma-ray facility is maintained by NPL’s Radiation Dosimetry group and is available for hire for short or long term gamma-ray irradiations with supporting dosimetry and technical services if required.
- The suite of X-ray facilities at NPL consists of three industrial and two clinical sets, covering a wide range of energies and applications.
