TRACERC PED-IS PERSONAL ELECTRONIC DOSIMETER T404 A 2 RADIATION MONITOR 18:42

TRACERCO PED-IS Personal Electronic Dosimeter T404A2

The TRACERCO PED-IS (Personal Electronic Dosimeter – Intrinsically Safe) T404A2 is a advanced, rugged, and highly reliable radiation monitoring device designed for personnel working in potentially hazardous environments. It provides real-time monitoring of accumulated dose and dose rate, ensuring the safety of workers in industries such as nuclear energy, decommissioning, radiography, healthcare, and emergency response.

Key Features & Benefits

• Intrinsically Safe (IS) Certification: This is a critical feature. The PED-IS is certified for use in hazardous and potentially explosive atmospheres, making it essential for oil & gas, petrochemical, and other industries where flammable gases or vapors may be present.

• Robust and User-Friendly Design: Built to withstand the demands of industrial use. It features a large, high-contrast display that is easy to read in all lighting conditions, a simple two-button operation, and clear audible, visual, and vibrating alarms.

• Dual-Detector System: Incorporates both a Geiger-Müller (GM) tube for high dose rates and a Silicon detector for high sensitivity at low dose rates. This provides accurate measurements across a very wide dynamic range.

• Comprehensive Data Logging: The device stores a detailed history of dose and dose rate data, including timestamps and alarm events. This is invaluable for compliance reporting, incident investigation, and dose tracking.

• Multiple Programmable Alarms: Users and safety officers can set customizable alarm thresholds for:

  • Accumulated Dose

  • Dose Rate

  • Stay Time (warning when a worker has been in an area for a preset duration)

• Sealed and Water-Resistant: The housing is sealed to protect against dust, moisture, and contaminants, ensuring reliability in harsh environments.

Technical Specifications (Representative)

• Data Storage: Extensive logging of dose, dose rate, and alarm events.

• Connectivity: Typically includes an infrared (IR) or optical port for communication with a docking station or reader for data download and configuration.

• Power Supply: Long-life, user-replaceable AA batteries.

• Environmental Rating: High IP rating (e.g., IP67) for dust and water resistance.

• Safety Certifications: ATEX / IECEx for Intrinsically Safe operation in explosive atmospheres. Compliant with IEC 61526 standards for personal dosimeters.

Typical Applications

The TRACERCO PED-IS T404A2 is ideal for any scenario where monitoring personal exposure to ionizing radiation is critical:

• Nuclear Power Plants: For routine operations, maintenance, and outage projects.

• Nuclear Decommissioning & Waste Management: Monitoring workers in high-risk, variable radiation fields.

• Industrial Radiography: Ensuring the safety of crews using radioactive sources for non-destructive testing.

• Oil & Gas Industry: For use on offshore platforms and refineries where naturally occurring radioactive material (NORM/TENORM) may be present, and Intrinsic Safety is required.

• Medical & Healthcare: Monitoring staff in radiology, nuclear medicine, and radiation oncology departments.

• Government & Emergency Services: For first responders, border security, and military personnel in radiological emergency situations.

• Research Laboratories: In academic and industrial labs using radioactive materials.

Conclusion

The TRACERCO PED-IS T404A2 is more than just a dosimeter; it is a comprehensive personnel safety system. Its robust construction, Intrinsically Safe certification, dual-detector technology, and advanced data management features make it a top-tier choice for organizations committed to the highest standards of radiological protection and regulatory compliance. It empowers both the wearer and safety managers with the critical data needed to work safely and minimize radiation exposure.
