Texas Industrial Radiography Gamma Practice Test

How should sources be handled during gamma radiography?

1. By personnel wearing protective clothing

2. By personnel without protective clothing

3. Using breathing apparatus

4. By qualified personnel using remote handling equipment

The correct answer is: By qualified personnel using remote handling equipment

In gamma radiography, handling radioactive sources must prioritize safety and minimize exposure to ionizing radiation. Using remote handling equipment is crucial because it allows qualified personnel to manipulate sources from a safe distance, reducing the likelihood of radiation exposure. This method is essential in maintaining a controlled environment where radiographers can work effectively and safely without direct contact with the sources, which can be hazardous. Remote handling equipment such as collimators, source changers, or cranes designed for moving radioactive materials enables professionals to follow safety protocols while ensuring that operations remain efficient. It is a critical practice in safeguarding personnel and ensuring compliance with safety regulations in the industry. While protective clothing can provide a level of shielding, it does not eliminate exposure risks, especially when working close to sources. Similarly, using breathing apparatuses is not necessary unless working in environments with airborne contaminants, which is not the primary concern in gamma radiography. Overall, reliance on qualified personnel and remote handling equipment is the most effective and safest practice for managing radioactive sources in this field.
