Comprehensive Calibration Services and Options
Complete Gauge Service and Maintenance
Our nuclear density gauge calibration provides comprehensive service beyond basic measurement verification. Each calibration includes:
Leak Testing: Required radiation safety testing that verifies sealed source integrity and prevents radioactive contamination. Leak testing meets NRC requirements and provides documentation for regulatory compliance and license maintenance.
Gauge and Case Cleaning: Thorough cleaning of gauge housing, measurement components, and transport case that removes field contamination, ensures proper operation, and maintains professional appearance for regulatory inspections and customer confidence.
Source Weld Inspection: Detailed visual inspection of radioactive source welds and shielding that identifies potential damage, wear, or degradation that could compromise source integrity or radiation safety.
Lubrication and Mechanical Service: Proper lubrication of moving parts, probe mechanisms, and locking systems that ensures smooth operation, prevents wear, and extends gauge service life under demanding field conditions.
Electronic Checkup and Adjustment: Comprehensive evaluation of measurement electronics, display systems, and control circuits with necessary adjustments and optimization that ensures accurate measurement and reliable gauge operation.
Calibration Block Options
3 Block Calibration: Standard calibration using three certified reference blocks that verify gauge accuracy across typical density ranges encountered in construction applications. This calibration option provides essential accuracy verification for routine construction quality control and regulatory compliance requirements.
5 Block Calibration: Enhanced calibration using five certified reference blocks that provides comprehensive accuracy verification across extended density ranges. This expanded calibration option ensures optimal accuracy for diverse materials, demanding applications, and projects requiring the highest measurement confidence.

Why Nuclear Density Gauge Calibration is Essential for Your Operations
Accurate Field Testing and Quality Control
Nuclear density gauges provide critical quality control data for compaction verification, pavement density testing, and moisture determination that determines whether construction materials meet project specifications. Inaccurate gauge readings can approve deficient materials that lead to premature failures or reject acceptable materials that cause project delays and disputes. Properly calibrated gauges ensure reliable field measurements that support construction quality and project success.
Regulatory Compliance and Licensing Requirements
Nuclear gauge operation requires strict compliance with NRC regulations, state radiation control programs, and transportation department requirements. Regulatory agencies mandate regular calibration, leak testing, and maintenance with comprehensive documentation. Proper calibration records are essential for license renewals, regulatory inspections, and continued authorization to possess and use radioactive materials.
Radiation Safety and Worker Protection
Nuclear gauges contain sealed radioactive sources that require proper handling, maintenance, and safety verification to protect workers and the public. Regular calibration includes leak testing that verifies source integrity and prevents radioactive contamination. Comprehensive safety inspections ensure proper shielding, locking mechanisms, and safety features that protect personnel from radiation exposure.
Transportation Compliance and DOT Requirements
Nuclear gauges must comply with Department of Transportation regulations for radioactive material transport including proper packaging, labeling, and documentation. Calibration services include verification of transport case integrity, safety features, and compliance with DOT shipping requirements that enable legal gauge transportation between project sites.
Project Acceptance and Payment Authorization
State DOTs, municipalities, and project owners require documented proof of gauge calibration and compliance for test result acceptance and payment authorization. Without current calibration certificates and leak test documentation, field test results may be rejected, causing project delays, payment disputes, and potential contract violations.
Insurance and Liability Management
Construction operations involving nuclear gauges require appropriate insurance coverage and liability protection. Insurance carriers often require documented calibration programs and safety compliance as conditions of coverage. Proper calibration records demonstrate due diligence and support liability protection when gauge operations become subject to safety investigations or legal proceedings.
