Dose Tissue

Tissue dose (TD) is an important parameter in medicine and radiation safety, since it reflects the amount of absorbed ionizing radiation energy throughout the human body. It is used to assess the risk of cancer, radiation therapy, and other medical procedures involving radiation.

Tissue dose is defined as the absorbed dose in body tissue, which can be measured using special devices - tissue dosimeters. These devices can be installed on the surface of the patient's body or inside it to measure the dose in various organs and tissues.

It is important to understand that each organ and tissue has a different tissue dose, and this can affect the treatment and prevention of disease. For example, during radiation therapy for lung cancer, the tissue dose to the lungs may be significantly higher than to other organs. This is due to the fact that the lungs are the most radiosensitive tissues of the body.

In addition, tissue dose can also be used to assess the effectiveness of radiation protection, for example when working with radioactive materials or when conducting medical research using ionizing radiation.

Overall, tissue dose measurement is an important tool for ensuring the safety of patients and staff and for optimizing the treatment and prevention of radiation-related illnesses.

Introduction

Tissue dose is one of the most important parameters that is used to assess the radiation risk for living organisms and the health of people exposed to ionizing radiation. It shows how much radiation is absorbed in a particular tissue or organ of the body. Tissue that absorbs a large dose of radiation can lead to serious illness and even death of the body. In this regard, tissue dose assessment is one of the most important tasks of radiation protection of the population and ensuring the safety of work with sources of ionizing rays.

Principles for assessing tissue dose

Tissue dose assessment is carried out using the formula:

D = (ƒ x S) / P, where D is tissue dose (Sv or Rem); ƒ - quality factor of the radiation source; S is the sum of absorbed tissue masses; P is the critical mass that determines the fraction of radiation absorbed by tissues.

The main factors of the quality of radiation sources include their penetrating ability and particle flux density or radiation power. So,
