A medical linear gas pedal is a device commonly used in medical radiation therapy, which uses high-energy X-rays or electron beams to treat diseases such as cancer. Under normal use, the screws are usually not radioactive. However, if the screws have been exposed to radioactive materials or have been irradiated, there may be a radiation hazard.
Therefore, if you remove a screw from a medical linear gas pedal, you should take appropriate precautions to avoid direct contact with the screw and dispose of it properly. It is best to contact the relevant professional or equipment supplier for guidance on proper disposal.
