ABSTRACT
The best weapon against radiation overexposure in the workplace is knowledge. To protect themselves from unnecessary exposure or overexposure, radiation workers must learn as much as possible about the nature, the types, the properties, and the interactions of radiations. They must learn also about the means of protection and the rules and regulations that guarantee their safety and the safety of the general public. To ensure a safe working environment in the NM department, technologists must be able to qualify and quantify radioactivity and radiation fields.
