ASNT Industrial Radiography Radiation Safety Practice Test

What is the maximum surface reading for a Yellow II labeled container?

1. 50 mR/h

2. 200 mR/h

3. 500 mR/h

4. 1000 mR/h

The correct answer is: 500 mR/h

A Yellow II labeled container is indicative of a specific level of radiation hazard and is often used to signify containers or packages that contain radioactive material. The maximum surface reading for a Yellow II labeled container is established to ensure safety for handlers and those in proximity to the container. This label implies that radiation levels at the surface of the container can reach up to 500 mR/h. This threshold is part of regulatory guidelines to categorize the level of radiation exposure risk. It ensures that while such containers can contain significant levels of radioactive material, they are still considered to be safe under controlled conditions, provided that appropriate safety measures are observed. Understanding these limits is crucial for personnel involved in industrial radiography to maintain safe practices and protocols.
