ASNT Industrial Radiography Radiation Safety Practice Test

What type of tube is used for the transport of radioactive sources in an exposure device?

1. S tube

2. D tube

3. R tube

4. T tube

The correct answer is: S tube

The correct answer is associated with the type of tube that is specifically designed to safely transport radioactive sources in an exposure device, which is critical for maintaining safety standards in industrial radiography. The S tube is tailored for this purpose, ensuring that the radioactive material is securely contained while allowing for the necessary transmission of radiation for examination purposes. The design of the S tube incorporates features that prevent leakage and unintentional exposure to radiation, which is essential to protect both the operator and the surrounding environment from hazardous exposure. This includes considerations for structural integrity and shielding. In contrast, the other types of tubes mentioned—D, R, and T tubes—do not serve the same function in the context of safely transporting radioactive sources within exposure devices. They may have different applications or characteristics that do not align with the safety and operational requirements of transporting radioactive materials. Understanding the purpose and special requirements of the S tube is vital for ensuring compliance with radiation safety regulations in industrial radiography.
