Environmental Radiation Dosimetry

The independent Panasonic® TLD platform for environmental monitoring.

As the dosimetry industry consolidates, ProxDose™ Monitoring remains the independent operator of one of the largest Panasonic TLD inventories in the field — purpose-built for environmental programs, REMP support, intercomparison validation, and Qsea™ scientific analytics. NVLAP and ISO/IEC 17025–aligned operations across the U.S. and seven international markets.

International deployment experience spanning the Americas, Africa, and Europe — markets where consolidated U.S. providers maintain limited direct presence

Capabilities

Environmental dosimetry, engineered for the long horizon.

ProxDose™ Monitoring delivers full-lifecycle environmental radiation programs. From station deployment and quarterly badge cycles to long-term trend analytics and regulatory documentation — built to last decades, not quarters.

01 / Environmental TLD Programs

Environmental TLD Programs

The overarching environmental framework — incorporating the Direct Radiation Monitoring driven by the ODCM and aligned with NUREG-1301 (PWR) and NUREG-1302 (BWR). Quarterly and annual TLD programs designed around your monitoring grid: site perimeter, exclusion area boundary, indicator and control stations.

02 / REMP & Utility Support

REMP & Utility Support

What we do for the licensee with the Environmental TLD Program. We design, deploy, and operate Direct Radiation networks around a site — the expertise developed running these programs for state regulators and commercial nuclear utilities.

03 / Intercomparison Validation

Intercomparison Validation

Above and beyond the ODCM-based REMP baseline — the independent check every program should run. Blind-irradiation campaigns with PNNL and other reference laboratories, aligned with ANSI/HPS N13.11 categories.

04 / Long-Term Networks

Long-Term Monitoring Networks

Also standing on its own, beyond the ODCM baseline — multi-year, multi-station networks operated for utilities and state regulators alike, including independent licensee-network monitoring performed on behalf of a state regulatory agency.

Assessments

Qsea™ is the scientific quality engine inside every ProxDose™ Monitoring program. While most providers consider QA/QC an internal cost, we treat it as the deliverable. Every dataset we publish is traceable, reproducible, and defensible under audit, NVLAP review, and inspection.

/01

ECF & Fingerprint Correction

Element Correction Factor calibration and individual-element fingerprint correction analytics for Panasonic UD-series readers — the foundation of low-uncertainty environmental measurement.

/02

ANSI/HPS N13.11 Performance Evaluation

Category-by-category performance evaluation. Pre-NVLAP readiness, blind-irradiation studies with PNNL and other reference laboratories, and corrective-action analysis where bias or precision drift is identified.

/03

QA/QC Analytics

Statistical process control for environmental and routine programs — control charts, trend detection, outlier flagging, and quarterly QA reports formatted for regulator review. Includes formal Verification & Validation (V&V) of dose-calculation software.

/04

NVLAP & ISO/IEC 17025 Readiness

Documentation systems, internal-audit playbooks, scope-of-accreditation support, and on-site or remote pre-assessment evaluations for laboratories pursuing or maintaining accreditation.

/05

Laboratory Validation Systems

Method validation, equivalency studies, and platform-transition validation packages — particularly for laboratories migrating between TLD generations or extending Panasonic platform service life.

The regulatory basis

The ODCM sets the framework. We work fluently within it.

Direct Radiation Monitoring is driven by each licensee’s Offsite Dose Calculation Manual (ODCM) and aligned with NRC standard guidance. ProxDose™ designs and operates networks to that framework — for utilities and for the state agencies that independently verify them.

Why ProxDose™

The independent specialist in a consolidating market.

In 2024, two of the industry’s largest providers absorbed independents — and the market continues to shrink. ProxDose™ Monitoring offers what conglomerates cannot: focused environmental expertise, platform continuity, and direct technical access — without the layers.

i.

A platform that doesn't disappear

The Panasonic® UD-series remains one of the most accurate TLD platforms ever built. While Panasonic ended factory support, we maintain one of the industry’s largest independent inventories of UD-710, UD-716, UD-7900 readers, irradiators, lamps, PMTs, slides, and replacement components — sufficient to support active environmental programs for decades.

ii.

Methodology continuity for long-running networks

For utilities and environmental agencies running 20+ year monitoring programs, switching platforms means breaking your historical baseline. ProxDose™ Monitoring lets you keep the methodology — and the trend integrity — that your existing data was built on.

iii.

Established international capability

Active deployment experience across Costa Rica, Ethiopia, Brazil, Mexico, Europe, Colombia, and South Africa. Through ProxDose™ Global, we support international laboratory deployment, regional radiation infrastructure development, and technology transfer — markets where the consolidated U.S. providers have minimal direct presence.

iv.

Lean overhead, senior responsiveness

An operationally lean specialty laboratory means decisions in days, not quarters; technical questions answered by the engineer doing the work; and pricing built around the program — not enterprise SaaS license tiers. NVLAP and ISO/IEC 17025–aligned, with a VA Radioactive Material License.
