Landauer

What Landauer does

Landauer is a U.S.-headquartered provider of radiation monitoring services and dosimetry devices, operating as a wholly-owned subsidiary of diversified industrial conglomerate Fortive Corporation from Glenwood, Illinois. Founded in 1954 and employing 501-1,000 people, the company is described in its own materials as the global leader in radiation science and services, serving approximately 78% of U.S. hospitals for occupational dosimetry alongside a broad set of adjacent verticals including medical and dental offices, cancer treatment centers, imaging centers, military and first responders, industrial radiography, veterinary clinics, and chiropractic offices. Its core technology is optical stimulated luminescence (OSL), embodied in the proprietary Luxel+ whole-body dosimeter badge and the OSLR Reader Series used to quantify ionizing radiation exposure.

Landauer's product portfolio is organized around three pillars: occupational dosimetry (Luxel+ badges, ring dosimeters, readers, and the myLDR digital client portal), medical dosimetry (the MicroSTARii secondary dose verification system for radiation oncology), and imaging physics and radiation safety services (accreditation support, equipment performance testing, shielding design, RSO support, and nuclear medicine physics consulting). Compliance and reporting products — including RadFacts Dashboards, Signature Suite, ALARA dose alerts, and Equivalent Form 4/5 reports — are delivered primarily through the myLDR portal, with specialized add-ons such as fetal monitoring for declared pregnant workers. LANDAUER Academy extends the offering into fee-based professional education across CT, fluoroscopy, MRI, dosimetry, and nuclear medicine/PET.

The business model is predominantly subscription/recurring: organizations pay for ongoing dosimetry monitoring programs priced by badge volume and exchange frequency (monthly, quarterly, semi-annually), complemented by professional services billed as project-based or retainer engagements (medical physics consulting, shielding design, accreditation support) and hardware sales of dosimeters and readers. The company goes to market through direct enterprise field sales (1-800-323-8830), the myLDR self-service portal, and authorized distributors, targeting Radiation Safety Officers and healthcare administrators via content marketing, webinars, and educational resources. Two notable historical acquisitions — Global Physics Solutions (2009) and IZI Medical Products (2011) — expanded the medical physics and imaging product footprint that today underpins the LANDAUER Medical Physics subsidiary.

Core offering

Landauer sells and services radiation dosimetry products and monitoring services to organizations that need to track occupational and medical radiation exposure. Its core offerings are the Luxel+ whole-body dosimeter badges (using proprietary optical stimulated luminescence technology), the myLDR client portal for compliance reporting, and a broad set of medical physics and radiation safety consulting services for hospitals, imaging centers, cancer treatment centers, and industrial facilities.

Product overview

Landauer offers a comprehensive radiation monitoring and dosimetry portfolio organized around its core Luxel+ dosimeter badges and myLDR client portal platform. The product line spans three main categories: (1) Occupational Dosimetry including whole-body badges (Luxel+), ring dosimeters, and readers (OSLR Reader Series); (2) Medical Dosimetry featuring MicroSTARii for secondary dose verification; and (3) Reporting & Compliance Services including RadFacts Dashboards, Signature Suite, ALARA notifications, and Equivalent Form 4/5 reports. Supporting services include LANDAUER Academy for education, Radiation Safety Training and Support Services for RSO assistance, Radiation Shielding Design for facility planning, and Imaging Physics Services for healthcare facilities. The company also provides fetal monitoring as a specialized add-on service. The portfolio integrates reporting, compliance tracking, and professional education into a unified ecosystem accessed primarily through the myLDR portal.
