Information about Dstl’s dosimetry services and how to use them.

The Defence Science and Technology Laboratory’s (Dstl) dosimetry services measure and record radiation workers’ exposure to ionising radiation such as X-rays, gamma rays, beta particles and neutrons.

About the facilities

Dstl offers a dose assessment and dose record keeping service. We are one of the largest dosimetry providers in the UK and have a long service history spanning more than 50 years.

Our services are approved by the Health and Safety Executive under the Ionising Radiations Regulations 1999 and the Requirements for Approval of Dosimetry Services. We undertake approximately 60,000 dose assessments every year. All of our dosemeters are maintained to the highest quality standard and we undertake regular performance tests as a requirement of our approval.

Dstl’s dosimetry services are open to all employers that have classified or unclassified radiation workers. For all categories of radiation workers, Dstl’s dosimetry services can provide a range of different dosimetry options to carry out dose assessments and to open and maintain dose records for individuals.

  • Extremity Thermoluminescent Dosemeters: to assess beta, gamma and x-radiation doses to the hands.

  • Environmental Thermoluminescent Dosemeters: to undertake environmental monitoring of low-level environmental gamma and x-radiations. Can be used inside or outside, and have been tested in all weather conditions.

  • Personal Radon Dosemeters: to measure a person’s exposure to Radon gas in the workplace.

  • Environmental Radon Detectors: to measure the Radon gas concentration in workplaces and dwellings.

  • In vivo monitoring: whole body, lung and thyroid monitoring to assess intakes of radionuclides.

  • Co-ordination and record keeping: we store and maintain personal dosimetry records in accordance with the Ionising Radiations Regulations 1999.
