Installing X-Ray Systems and X-Ray in Use Lights – What to Know

Dec 2, 2020 | Articles, General Imaging

Medical x-rays play an important role in the diagnosis and treatment of patients. As they can generate images of structures in the body, they are commonly used to examine bones and joints. In particular, they can help detect bone fractures and breaks. Sometimes, they are also used to identify problems with internal organs.   

With that said, it’s worth remembering that unnecessary exposure to radiation through x-rays can harm living tissues in the body. Especially with frequent exposure, it can present some health risks.  

Considering this, you must see to it that the essential safety precautions are installed along with your x-ray system. One particular device you will need is the “X-ray in Use” light. 


What is the “X-ray in Use” Light And Why Do You Need It? 

This device is usually installed right outside radiological exam rooms to signal when x-rays are being produced. This helps keep patients as well as medical staff safe from passing through an active x-ray area. Consequently, this helps reduce the chances of unnecessarily exposing others to radiation. 

Aside from keeping the people inside your healthcare facility safe, there are other reasons to install these devices. In fact, there are certain guidelines and regulations on the installation of “in use” lights. Take note, however, that these regulations vary depending on the state or country you are in. 

To make sure that your center is fully compliant with these ordinances, it is best to get in touch with your local health or radiological department. 


How Are “X-Ray in Use” Lights Installed? 

If your local health authorities require these devices, you have the responsibility of installing these along with your x-ray system. Furthermore, you have to maintain it and ensure that it is working properly. 

The bright side is that your equipment providers and electrical contractors will do all the legwork for you. All you need to do is get in touch with the right professionals and schedule the installation thoughtfully. 

Before your equipment providers deliver the x-ray system to be installed, it’s a smart move to work with your electrician to prepare a 110 VAC or 24 VAC fixture with two relay wires. These will be for the x-ray in use light. Afterward, see to it that the wires are long enough to reach where your x-ray generator will be placed. 

Once your x-ray device arrives, you can ask the help of your electrician to link it to your in-use light. Connecting the two will turn the latter on and off every time power is applied to or removed from the x-ray tube. 



While x-rays can be helpful in how you diagnose or treat your patients, the radiation it emits can present health risks to both your patients and staff. Considering this, you must see to it that you install your system properly along with a functioning “x-ray in use” light. On top of that, remember to conduct periodic testing and routine maintenance to keep all components in tiptop shape. Ultimately, all of these efforts will help you keep your facility not only efficient but also safe for everyone.
