I. Introduction
Radiological mapping plays a crucial role in dismantling and decommissioning (D&D) nuclear installations. It involves determining the facilities’ radiological condition, which helps identify potential contamination areas. In France, most radiation-protection operators (RPOs) still rely on manual radiological mapping, which is time-consuming, exposes them to potentially contaminated environments, and is prone to human errors. This is mainly because the existing literature lacks a system that can reliably perform radiological mapping during the dismantling of nuclear installations, considering the French facilities’ characteristics and the procedures followed by RPOs in various scenarios and nuclear measurements.
