Project Introduction

In complex and hazardous environments, risks are often not isolated.
Toxic and hazardous gases, flammable gases, oxygen-deficient environments, and nuclear radiation hazards may all be present at the same site simultaneously. Conventional detection methods rely on multiple devices operating in sequence, which not only prolongs workers’ exposure but also reduces on-site decision-making efficiency.

Sosk’s handheld gas–nuclear radiation integrated solution centers on integration, portability, and rapid response, consolidating gas detection, nuclear radiation monitoring, alarm signaling, data logging, and wireless transmission into a single device. It enables users to swiftly conduct on-site identification, risk assessment, and documentation, making it ideal for a wide range of applications, including industrial safety, environmental monitoring, underground operations, border‑crossing inspection and quarantine, and emergency rescue.

I. Why an Integrated Testing Solution Is Needed

At many high-risk job sites, the real question isn’t “can we detect it,” but rather:

1. The sources of risk are complex, and a single device is insufficient.

In the same environment, flammable gas leaks, toxic and hazardous vapors, oxygen deficiency, and radiological hazards may coexist. Conducting separate measurements with multiple devices is not only cumbersome but also prolongs the duration of operations.

2. The on-site window is short, so results must be obtained more quickly.

In tasks such as accident response, confined-space monitoring, and the identification of suspected contamination zones, the speed of data acquisition directly impacts operational efficiency. The faster reliable data are obtained, the greater the benefits for personnel safety and on-site decision-making.

3. In harsh environments, equipment must be reliable.

Conditions such as high temperature, low temperature, humidity, dust, underground environments, enclosed spaces, confined areas, and mobile operations place heightened demands on equipment’s protection capabilities, stability, and portability.

4. Testing should not only focus on the results but also involve maintaining thorough records.

For applications such as regulatory record-keeping, task traceability, emergency post‑event reviews, and accident analysis, on-site readings alone are far from sufficient; equipment must also be capable of data storage, transmission, and retrieval.

5. What frontline staff really need is “less equipment and faster task completion.”

On-site personnel want equipment that is lighter, faster, and more intuitive, rather than having to switch back and forth between multiple instruments.

 

II. What problems can the Sosk solution address?

Sosk’s handheld gas and nuclear radiation integrated solution, centered on “ Rapid detection, real-time assessment, over-limit alarms, data retention, and closed-loop task management. “Built to help users transform complex environmental monitoring—from multi-device, multi-process, and multi‑person collaboration—into a more efficient, integrated operational model.”

IV. Key Highlights of the Plan

True integration of gas detection and nuclear radiation sensing

Many on-site situations are not “single risks” but rather “compound risks.”
Sosk’s integrated solution enables users to obtain both gas and radiation data on a single device, thereby minimizing decision‑making blind spots.

Rapid response, ideal for real-world missions.

On the real site, speed is safety.
The device is designed for rapid screening and quick confirmation, enabling users to complete environmental assessments in a shorter timeframe.

The synergy of multiple detection principles enhances scene adaptability.

Different target substances, concentration ranges, and environmental conditions impose varying requirements on detection principles. By combining multiple principles, it is possible to achieve both broad coverage and reliable detection.

Multi‑alarm system, better suited for complex environments.

Under conditions of high noise, poor lighting, and a tense environment, a single reminder method is often insufficient.
A multi-dimensional alerting mechanism can effectively enhance on-site situational awareness.

More comprehensive data closed-loop capabilities

From detection to storage, and from querying to data transmission, it supports not only on-site operations but also downstream management, reporting, and traceability.

Truly designed for mobile operations

Handheld, integrated, and portable—ideal for a wide range of mobile tasks, including inspections, spot checks, routine maintenance, and incident response.

 

V. Demonstration of Core Competencies

Rapid testing capability

Composite risk identification capability

It can detect toxic, hazardous, and combustible gases while simultaneously performing nuclear radiation detection, making it particularly well-suited for complex, uncertain, and high-risk environments.

Efficient On-Site Interaction Capability

The high-definition display, combined with touch-based interaction, enables frontline personnel to quickly access critical information even in complex environments.

Real-time early warning capability

Once a measured value deviates from the norm or exceeds the preset threshold, the system can immediately trigger an alarm to alert personnel and enable them to promptly adjust their operational strategies.

Data Storage and Retrospective Capabilities

Supports on-site result retention, facilitating subsequent queries, analysis, and the generation of task reports.

Wireless Connectivity and Positioning Capabilities

It facilitates on-site data transmission, device network management, and task‑location logging, thereby enhancing the overall manageability of the solution.

VII. From On-Site Testing to Task Closure

Compared with single-point devices that merely provide “readings,” Sosk places greater emphasis on the closed-loop capability of the entire operational workflow.

Step 1: Quick positioning

Handheld deployment enables rapid on-site access, making it ideal for mobile and ad-hoc operations.

Step 2: Synchronous Detection

Conduct simultaneous gas and nuclear radiation monitoring in the target area to minimize redundant operations.

Step 3: Immediate Alarm Activation

Once an anomaly is detected, the system immediately issues an alert to help on-site personnel take timely action.

Step 4: Auxiliary Judgment

Based on the test results, data-driven guidance is provided for personnel access, area segregation, risk level assessment, and subsequent response measures.

Step 5: Data Logging

The collected data can be stored, queried, and transmitted back to the system, providing support for management and post-event analysis.
