Field-proven detection systems
Field-proven detection and telemetry systems — area monitors, portable detectors, air-monitoring units, and mesh-networked remote sensing for distributed site monitoring. Built for harsh conditions, engineered for continuous data transmission.
RadSight — dosimetry and monitoring
Unified exposure records, real-time environmental monitoring, and access control across single or multi-site operations. Fully compatible with Mirion and Thermo Fisher systems.
24/7 technical support
Engineering teams in the UK and US, available around the clock. Remote diagnostics, on-site response, and full asset lifecycle management from installation through to end of service. Uncompromising safety and value — at every stage.

Trusted in facilities where the
‍ quality of data protects people

Still running ageing radiation monitoring infrastructure?

Legacy systems don't fail overnight — they become harder to calibrate, harder to source parts for, and increasingly difficult to justify under modern regulatory scrutiny. Charthouse instruments are designed as direct, like-for-like replacements for end-of-life monitoring equipment — engineered for minimal disruption, maximum operational continuity, and designed to adapt as your monitoring requirements evolve.

About Charthouse
28 years building systems that the world's most critical facilities rely on.
Charthouse was founded with a single purpose — to create safer working environments through better radiation data. Since 1996, we have been building the hardware, software, and support systems that nuclear utilities, defence agencies, and healthcare facilities rely on to protect their people.

We do not resell generic instruments. We design, engineer, and support integrated monitoring systems for the specific demands of safety-critical industrial environments, including remote telemetry networks for multi-point site coverage — because consistent performance and accountability don't stop at installation.
28+
Years in Operation
Charthouse has been designing and supporting radiation monitoring systems since 1999 — through changes in regulation, technology, and the facilities we serve.
4
Continents Served
Deployed across nuclear, defence, and healthcare facilities in North America, Europe, Asia, and Australia.
24/7
Support
Round-the-clock technical support from engineers who know the systems. 
Not a call centre — the people who built it.
