ASNT Industrial Radiography Radiation Safety Practice Test

What was a significant cause of personnel overexposure in the early years of radiography?

1. Poor equipment design

2. High radiation levels

3. Advanced safety practices

4. Accurate surveys

The correct answer is: Poor equipment design

In the early years of radiography, a significant cause of personnel overexposure was indeed poor equipment design. Early radiographic equipment often lacked proper shielding and safety features that are now standard in modern devices. This inadequate design meant that radiographers were exposed to higher levels of radiation while performing their work. At that time, the emphasis on radiation safety was not as developed as it is today. As a result, workers frequently found themselves in situations where they could not effectively limit their exposure due to the equipment's limitations. The understanding of dosimetry and the importance of personal protective equipment were also not as advanced, making it challenging for personnel to safeguard themselves against radiation hazards. This historical context highlights why ongoing improvements in technology and safety protocols have become crucial in preventing overexposure and ensuring the safety of workers in the field.
