Dose Superficial

Surface dose is the absorbed dose of x-ray or gamma radiation at a given point on the surface of an irradiated object. X-rays and gamma rays, for example, are used to diagnose diseases, treat tumors, and in industry for welding and other operations.

Surface dose is measured by calculating the number of photons that reach the surface and are absorbed by the substance. The number of photons is calculated based on the power of the X-ray source, the geometry of the beam, and the distance between the source and the surface. Then, based on the information obtained, the amount of absorbed dose is determined.

It is important to understand that surface dose is not an accurate indicator of a person's health or the effectiveness of medical procedures, but it is an important factor in determining the safety of radiation exposure. If the radiation dose is too high, severe tissue damage and even death can occur. Therefore, it is important to strictly control the surface dose and limit the level of radiation to a safe level.

There are various methods for reducing the surface dose, such as the use of protective screens, changing the angle of the radiation source, using different imaging methods, and others.

Introduction

Surface dose (also known as gamma percent dose) is a concept associated with exposure and radionuclide dosimetry. This is one of the main dosimetric quantities used by researchers studying nuclear medical technologies and the use of radioactive isotopes for therapy. It measures the absorbed dose at a specific point and depth on the surface of an object.

Description

Surface dose characterizes the amount of energy to which the surface of an object is exposed during irradiation. It is measured using special devices called dosimeters. The device records the radiation that is absorbed by the surface tissue and estimates its amount. This means that when measuring the surface dose, the amount of radiation that has been absorbed into the
