The document , titled "Central Axis Depth Dose Data for Use in Radiotherapy" , is a cornerstone reference in medical physics and radiation oncology, published by the British Institute of Radiology in 1996 . It provides standardized "golden data" for radiotherapy treatment planning, specifically focusing on how radiation dose varies with depth in water for different beam types and energies.
