Phoenix Dosimetry

What Phoenix Dosimetry does

Phoenix Dosimetry Limited is a UK-based specialist distributor and service provider of radiation detection and dosimetry equipment, founded in 2013 and headquartered in Sandhurst, Berkshire. The company supplies a comprehensive portfolio of radiation monitoring and dosimetry products to hospitals, radiotherapy departments, nuclear facilities, defence organisations, and academic research institutions across the UK and Ireland. It holds the exclusive UK distribution rights for the Harshaw TLD product range manufactured by Thermo Fisher Scientific, and also distributes equipment from Polimaster, Par Scientific, PHDS, femto-TECH, Codeac Solutions, TALS, and Helgeson. Its product lines span electronic personal dosimeters (TruDose, Polimaster Radflash), portable radiation monitors (RadEye B20, PRD4, SPRD, NL, HEC), TLD readers (Harshaw models 3500, 5500, 6600, 8800), ionisation chambers (NE2571 Farmer), water phantoms, radon monitors (femto-TECH CRM-LPT), handheld isotope identifiers (PHDS GeGI), mould room equipment, and supporting software platforms such as RadSight.

Phoenix Dosimetry operates a direct field-sales model supported by regional sales representatives (e.g., Mike Sweeney as Director, Dawn Broadhead covering Northern UK) and supplemented by active participation in industry exhibitions including the SRP Annual Conference, IRMF, IPEM events, AURPO, CARM, and Security and Policing. Revenue is generated across four streams: hardware sales across the distributed product portfolio, repair services (charged at GBP 90 per hour for legacy NE and Thermo equipment), TLD training courses delivered in partnership with Rotunda Scientific, and UKAS-accredited calibration services. The calibration capability is provided through its parent HTSL Group's accredited laboratory in Deeside, which services all makes and models of radiometric equipment.

Phoenix Dosimetry is a wholly-owned subsidiary of HTSL Group Limited and operates alongside sister companies High Technology Sources Limited and Euroteck Systems UK Limited. The company holds ISO 9001:2015 certification, is an affiliated member of the Society for Radiological Protection (SRP), and received the SRP Affiliated Organisation Award in 2023. Its named customer base includes the NHS, Sellafield, AWE, DSTL, Cavendish Nuclear, NPL, UKHSA, and UK universities, with a team of approximately 9 employees.
