As the world begins to embrace the power of nuclear energy again, there is a need to ensure these facilities are always safe to avoid some of the catastrophes the world has witnessed in the past. One of the measures is to inspect them regularly with the best equipment, like nuclear imaging cameras. According to the International Atomic Energy Agency, the lack of frequent inspection has led to about 20% of reported safety breaches in nuclear plants.
This is why these cameras are a must-have for any agency directly handling nuclear or related products. They ensure higher precision and accuracy during inspection and leak detection. With that, you can ensure the rooms are radiation-free and that any materials around the facility used for nuclear storage are best suited for the role. They are also more advanced in inspecting spaces and materials with nuclear exposure.
Despite their versatility and suitability for such duties, precautions are still needed when using them in hazardous spaces. So, before using them, master these tips for inspection camera usage and general safety.
1. Understand The Camera Capabilities
Sellers can sometimes cut corners and sell you a camera that is not up to the highest standards for nuclear inspection. So, you must examine it to ensure it can seamlessly achieve the task.
To do that, you should focus on the key features that make it suitable for such dangerous tasks and ensure you are safe using it. What matters most are the integrated features that make it ideal for any usage, including inspecting smaller vessels and tanks.
A reasonable nuclear inspection camera should feature a color camera to detect visual and color changes for issues like faint leaks. High-intensity lighting is another feature that contributes to faint leak detection and higher accuracy. The light is essential to detect leaks or measure the depth of the tank to ensure suitability for storing nuclear material.
Since the environment where you use the camera may have other impurities, including radiation particles, you must consider the camera’s external design. First, it should have a casing to withstand extreme temperatures.
Secondly, it should also prevent any material from sticking to its surface. The non-stick surface will prevent hazardous material from transferring from the camera to the human body upon contact. The casing should be made of non-stick, rust-free and easy-to-clean material.
Additionally, it should be thick enough to withstand corrosion or reaction from nuclear waste. Before purchasing it, get a nuclear test certification for the casing and camera.
2. Do A Routine Check and Maintenance
Unlike other cameras, these cameras should undergo intense maintenance under certain conditions. For instance, they should be subjected to infrared rays to detect any dents or holes in the body, which can limit their effectiveness.
Due to the heat, lenses can be damaged over time; hence, you should replace them frequently and dispose of the removed lenses properly. You should never reuse any lenses. Also, inspect the tightness after lens replacement to ensure no open spaces.
Finally, you should inspect the casing to ensure efficiency and reliability as a radiation shield. During the process, you can inspect the batteries and cables to ensure no damage or replace the old ones. Ensure you wear protective gear, including gloves, to avoid contamination.
3. Use Them from A Safe Distance
Despite having the camera and the protective suits, you should maintain a safe distance when inspecting. The ideal method is to stretch out your arms to ensure you are an arm’s length away from the surface you inspect. That distance is suitable when inspecting vessels and tanks with nuclear vessels.
If possible, attach the camera to remote operating systems to avoid holding it for too long. It is better to mount the cameras on drones and fly them to the area you wish to inspect. This method is perfect for checking the radiation level in contaminated spaces.
4. Use LED or Proper Lighting
Despite having infrared and thermal properties, these cameras work best when the room has sufficient lighting. That is why they have in-built lighting; however, you still need additional lighting, like drone or surface lights.
With proper lighting, you can identify faint leaks or tiny dents that could lead to leaks in the future. So, avoid using them in dark and poorly lit areas. Also, remember that not every lighting will be suitable for nuclear inspection.
The best ones are the high-intensity LEDs. With such lighting, you can easily avoid reflections, which can distort the image sent to the remote system for analysis.
5. Train Before Using Them
Note: Only the highest-trained personnel should handle these cameras, even when inspecting areas with low radiation levels. The training should also include protection for personnel entering the rooms and using cameras.
You must understand how to adjust features like sensitivity level to collect the best data. Before you begin the inspection, pay attention to the positioning, that is, the angular positioning of the camera and the distance from the main object you are inspecting.
All the training you need is in the camera manual; others are in nuclear safety manuals. Both trainings are critical and handy for any environmental inspection.
Concluding Thoughts
Negligence and improper handling of these cameras could have devastating consequences, hence the need to prioritize safety. You should maintain them regularly and change key components for higher accuracy. Only the best, the best-trained teams should handle the cameras. During the inspection, ensure the room is well-lit to boost accuracy and high-standard inspection results.
Wear protective gear to avoid direct contact with radiation or nuclear particles. Finally, it is best to operate the cameras remotely using gadgets like robots or drones.
