Irradiation Field Dosimetric

Irradiation field (IF) dosimetric is the area in which the human body or other objects, such as equipment or materials, are exposed to radiation. It is defined as the portion of space where the radiation dose exceeds a certain level, usually 50% or 80% of the maximum dose that the object can withstand.

The LO limit is calculated using the isodose curve, which shows what radiation dose will be received at a certain distance from the radiation source. Isodose curves can be plotted for various types of radiation such as X-rays, gamma rays, protons and others.

When using dosimetric software, it is necessary to take into account its size and shape in order to ensure safe exposure to radiation on the object. For example, when taking x-rays, the size and shape of the object must be taken into account in order to obtain a sufficient image without overexposing or underexposing.

It is also necessary to take into account that dosimetry software can be used to measure the radiation dose that a person or object receives when exposed to radiation. This can be useful for quality control of medical procedures, for example in the treatment of cancer or other diseases.

In general, dosimetry software is an important tool for ensuring the safety and effectiveness of radiation exposure to objects and people.

Irradiation field (RF) is a part of a radiosensitive medium in which the attenuation of the intensity of ionizing radiation and other properties significantly depend on the point of its intersection with the ICU projection. FO is characterized by radiometric parameters, which are established based on the results of dosimetric monitoring and are included in the corresponding measurement protocols.

One of the important parameters of the FO is the dose field, where the corresponding curve, equal to D-10% or W30%, passes.

Under the conditions of existing irradiation installations P.o. is usually determined by measuring the dose rate outside the irradiation installation directly behind the limiting lead protective screen (the reading is an X-ray counter). This calculation corresponds to the maximum dose rate. In the presence of absorption in the chamber wall and surrounding structures, the gamma dosimeter readings are calculated taking into account their absorption coefficient.

All F. have certain functional dependencies of the field radius (R), its depth (h), and the length of the working part of the F (d). Dimensions of working fields neo
