Module 10.2: Practical Factors 
Instructor's Notes 
D. 
Introduction 
Prior knowledge of radiological conditions can 
reduce unnecessary personnel exposure. Using 
proper radiological techniques and information 
provided by Radiological Control personnel will 
help ensure a safe working environment for all 
employees. 
Each site shall develop a practical factors evaluation 
for High Radiation Radiation Areas (as applicable). 
The site may choose to incorporate the High 
Radiation Area practical factor into the 
Radiological Worker I practical factors, or develop 
a separate practical factors lesson for High 
Radiation Areas.
