LANDAUER

What LANDAUER does

LANDAUER provides occupational radiation dosimetry services and equipment for monitoring personnel exposure to ionizing radiation across healthcare, nuclear, industrial, and research environments. The company's core offering is a subscription-based passive dosimetry service that manufactures detectors, ships them to customers on monthly or quarterly wear cycles, collects them for analysis, and delivers regulatory-grade dose reports retained for at least 50 years, supported by a free online account management portal (myLDR) that handles program administration, dose reporting, e-sign workflows, and data export.

The technical foundation rests on three proprietary detector technologies: Optically Stimulated Luminescence (OSL) using carbon-doped aluminum oxide (Al2O3:C) crystal grown in-house at the Stillwater, USA Crystal Growth Facility, with 40-60 times the sensitivity of competing LiF thermoluminescent materials; Thermoluminescent Dosimetry (TLD) with lithium fluoride for extremity (SATURN ring) and lens-of-eye (VISION) applications; and CR-39 Solid State Nuclear Track Detection (Neutrak) for thermal, intermediate, and fast neutron dosimetry. The product portfolio comprises Luxel+ (whole-body OSL), SATURN (TLD extremity ring), VISION (TLD lens-of-eye), Neutrak (CR-39 neutron insert), TLD Chip (single-point environmental), RaySafe 452 (multi-function survey meter), RaySafe i3 (real-time electronic dosimetry), and the INLIGHT/OSLR laboratory reader system. Imaging technology is automatically triggered on dose readings above 5 mSv to characterize exposure conditions.

LANDAUER operates as a division of Fluke Corporation (under Fortive Corporation), with a European SAS headquartered in Vélizy-Villacoublay, France, a UK operational subsidiary in Kidlington, and a US parent holding entity that runs the Stillwater crystal facility. The business is sales-led, combining dedicated field account managers, direct dosimeter delivery and collection logistics, and the self-serve myLDR portal. Revenue derives from recurring dosimetry monitoring subscriptions and equipment sales (readers, INLIGHT system, RaySafe instruments). The customer base of approximately 100,000 spans 30+ countries, anchored by HSE-approved service for the UK and EPA-approved service for Ireland, with verticals in healthcare, nuclear power, industry, and research/laboratories. Certifications include HSE, EPA Ireland, NVLAP Lab Code 100518-0 (categories IB, IC, IIC, IID, IIIB, IIIC, IIID, IVBB), ISO 21909:2005, IEC 62387-1:2012, ANSI N13.32 conformance, and GDPR compliance.

Core offering

LANDAUER provides a complete passive radiation dosimetry service that includes the manufacture of OSL (Optically Stimulated Luminescence), TLD (ThermoLuminescent), and CR-39 based personal dosimeters, distribution and collection of monitors on subscription cycles, laboratory analysis, dose reporting, and long-term record keeping. The company also sells dosimetry laboratory equipment (OSL readers, INLIGHT systems, RaySafe survey meters) for hospitals, nuclear power plants, industrial facilities, and research institutions worldwide.

Product overview

LANDAUER is a dosimetry services and equipment company offering a portfolio of passive dosimetry products organized around its myLDR online management platform. The core offering comprises five main dosimeter brands: Luxel+® (whole-body OSL dosimeter for X/gamma/beta), Neutrak® (integrated CR-39 neutron detector that slots into Luxel+®), SATURN® (TLD ring dosimeter for extremity dose), VISION® (TLD lens-of-eye dosimeter), and TLD Chip (single-point environmental TLD). These are supported by accessories including the Badge Board (organization/storage board) and Strap for VISION® (head strap). Equipment products include the INLIGHT® OSL dosimetry system with OSLR readers for laboratory use, the RaySafe 452 radiation survey meter, and the RaySafe i3 real-time dosimetry system. All products are managed through the myLDR online portal, which provides dose reporting, participant administration, and data export. LANDAUER also offers full-service dosimetry monitoring (distribution, collection, analysis, reporting, and record keeping) approved by UK HSE and Ireland EPA.
