Dóziseloszlás refers to the distribution of radiation dose to a specific area or volume. It is a crucial concept in fields such as radiation therapy, nuclear medicine, and radiation protection. Understanding the dose distribution is essential for determining the effectiveness of a treatment, assessing potential risks to healthy tissues, and ensuring safety protocols are met.

In radiation therapy, the goal is to deliver a high dose of radiation to a tumor while minimizing the dose to surrounding healthy organs. This requires careful planning and precise delivery of radiation beams, resulting in a complex three-dimensional dose distribution. Imaging techniques and sophisticated treatment planning software are used to predict and optimize this distribution.

In nuclear medicine, radiopharmaceuticals are administered to patients, and their distribution within the body is tracked. The resulting dose distribution depends on the biodistribution of the radiopharmaceutical, its physical decay characteristics, and the patient's anatomy. This information is used for diagnosis and treatment monitoring.

For radiation protection, dose distribution helps in assessing the potential harm from occupational or environmental exposure. It involves understanding how radiation scatters and penetrates different materials, and how it is absorbed by biological tissues. This knowledge informs the design of shielding, the establishment of safety limits, and emergency response procedures. Accurate knowledge of dose distribution is fundamental to maximizing therapeutic benefits while minimizing adverse effects and risks.
