This document provides information about planning nuclear medicine facilities. It discusses what nuclear medicine is and common applications like diagnosis of hyperthyroidism and bone scans. It also covers commonly used radiopharmaceuticals like Tc-99m and I-131. Facility layout plans are shown for areas like gamma camera, PET, and high dose therapy. Shielding calculations are provided for these areas based on workload, radiopharmaceutical half-lives, and regulatory dose limits. Thickness of concrete required is calculated using transmission values.
