Enterprise and workplace environmental monitoring for corporate offices, regional
schools, daycares, high-density residential properties, and institutional spaces

We execute both 3-7 day screening windows and complete 90+ day diagnostic series according to building needs.
Scintillation Lab Reporting
Analyzed strictly by certified Canadian radiological labs featuring continuous digital traceability.
1. Consultation
Direct initial assessment of structural square footage, custom blue print analysis, and flat project budgeting.
2. Strategic Planning
Coordinating device placements with local property managers, drafting clear tenant or employee leaflets.
3. Device Deployment
C-NRPP technicians deploy closed anti-tamper radon chambers strategically aligned with CNSC guidelines.
4. Testing Window
Passive chambers accumulate precise environmental data, during which standard business runs unaffected.
5. Lab Retrieval
Devices are sealed and routed to certified analytical laboratories for high-accuracy scintillation testing.
6. Master Reporting
Compiling location-by-location data sheets, compliance visual bar charts, and engineering advisories.
7. Follow-Up Review
Providing stakeholders with legal-compliance documentation, board summaries, and mitigation plans if needed.
Commercial radon testing requires absolute transparency in recording. Our master report packages satisfy school boards, workspace regulators, insurance underwriters, and legal counsel. Each report features:
Building Executive Summaries
High-level board-ready paragraphs explaining overall air health status simply.
Sensor-by-Sensor Location Graphs
Accurate trace records demonstrating exactly where each detector was active.
Vapor Barrier & Foundation Advisories
Physical diagnostics noting entry fissures or mechanical ventilation blockages.
Commercial Remediation Estimations
Clear mitigation strategies detailing options and clear flat costs if levels exceed guidelines.

Placements: 14 units
Average value: 34 Bq/m³
We monitor, calculate, and document workplace safety levels precisely under all
major Canadian occupational codes.
200 Bq/m³ Action Limit
Remediation must be commenced as soon as possible if concentrations in heavily populated zones cross above this core baseline.
Clause 25 General Duty
Employers are required to identify and take all reasonable precautions to protect workspace assets against environmental exposure hazards.
Part 9 Safety Measures
Regulates physical vapor mitigation provisions, gravel extraction conduits, and floor penetrations during renovations.
Managing complex multi-family blocks requires careful engineering. Shared foundations and heat-recovery ventilation (HRV) units create varying airflow environments. To protect tenants cleanly without raising alarm, our multi-unit plan incorporates:
Common Area Screenings
Placing sensors in concrete elevator lobbies, central service corridors, basements, and utilities hubs.
Strategic Ground Unit Sampling
Testing a representative 10-25% subset of apartments on the lowest living levels to audit soil ingress points.
Quiet Resident Communication Leaflets
Providing pre-written newsletter templates explaining natural radon tests simply to prevent tenant concern.
Historical Landlord Compliance Sheets
Producing structured environmental reports that secure and support building valuations during real estate sales.

🎯 Green dots represent high priority core tracking points placed touching slab levels.
Because children are in active development stages, long-term environmental radiation risks are significantly magnified. Our educational specialists maintain extensive school board experience. We guarantee:

Challenge: 8-story building housing 150+ staff had never completed certified radiological testing. Property managers required non-disruptive solutions.
Results achieved: Identified levels over 200 Bq/m³ in 3 occupied basement rooms. Provided clear plans allowing HVAC adjustments that resolved the issues cleanly.
Challenge: School board environmental protocols required comprehensive checks across 22 classrooms prior to school start. No learning disruptions permitted.
Results achieved: Deployed passive test chambers over a brief break period. 2 specific basement science labs tested positive and were mitigated safely during summer holidays.
Challenge: Concerns raised by first-floor occupants required a defensive property management audit that protected long-term valuations.
Results achieved: Tested common utility structures plus a 24-unit random sample. Developed a master compliance database demonstrating safe conditions across 92% of lines.
Commercial frameworks utilize custom ratios according to the building's footprint touching earth. According to standard CNSC & C-NRPP guidance, testing must be deployed in every occupied basement office, or room touching the ground slab, and at least once per 2,000 sq ft in larger open-concept store layouts. Our initial blueprint audit defines these points perfectly.
Yes. In fact, commercial passive radon devices are exceptionally quiet, small (similar to a coffee cup diameter), and run completely inertly. They require zero power and do not emit sound. They are secured with specialized labels to prevent tamper actions, allowing your employees, clients, or students to function as normal.
Short-term testing (typically 3 to 7 days) acts as an expedited commercial screening tool, ideal during active real estate transactions or immediate workplace hazard queries. Long-term testing (90+ days, ideally during cold winter heating seasons) represents the gold standard. Regulators and CNSC guidelines heavily prioritize long-term results because seasonal drafts cause massive variance.
There is no need to worry. Elevated radon is standard in the Ottawa limestone basin, and can always be resolved. If high readings occur, we present customized commercial mitigation proposals—such as upgrading central HVAC pneumatic exchange airflows or installing dedicated active sub-slab depressurization systems.
While there is no strict federal building law mandating pre-emptive alerts, transparency is highly recommended under Ontario's OHSA obligations which guarantee the 'right to know' of potential workplace exposures. We back your teams up by providing fully written tenant email newsletters and employee bulletin leaflets that explain testing simply.
Yes. Professional environmental surveying and air-quality monitoring services are fully deductible as standard commercial structure maintenance expenses or building workspace operations costs. Contact your corporate accountant to claim appropriate corporate write-offs.
