ASNT Industrial Radiography Radiation Safety Practice Test

Exposure devices are categorized into which two categories according to ANSI standard N432?

1. Static and Dynamic

2. Category I and Category II

3. Type A and Type B

4. Mobile and Portable

The correct answer is: Category I and Category II

The categorization of exposure devices according to ANSI standard N432 is indeed based on two main categories: Category I and Category II. This distinction is important as it helps to classify the exposure devices based on their design, usage, and the inherent safety measures that they provide. Category I devices are typically designed to be used in a more controlled environment and incorporate built-in shielding and safety features that assist in minimizing radiation exposure to personnel. These devices are often utilized in settings where strict regulatory compliance is required, and their design facilitates safe operation with less risk of accidental exposures. On the other hand, Category II devices may be used in a wider range of applications, including fieldwork, where portability and ease of setup are required. These devices might not have the same level of built-in safety features as Category I devices, thus necessitating more stringent operational protocols and training for personnel to ensure safety while using them. Understanding this classification helps professionals in the field of industrial radiography to choose the appropriate device for their specific applications while ensuring compliance with safety standards intended to protect workers and the public from the hazards associated with radiation exposure.
