Limited Part of the Population

**Limited part of the population** (synonym - category B exposed) is a part of the population that, due to its social or professional characteristics, has an increased risk of exposure to ionizing radiation. These people may be exposed to higher levels of radiation as a result of certain working conditions, living near radioactive sites, undergoing medical procedures, etc.

**Radiation hygiene** is a science that studies the effects of ionizing radiation on the human body and the environment. She studies both natural and man-made sources of radionuclides and develops measures to reduce the impact of radiation on people.

A limited part of the population belongs to group B exposed. By definition, she may be at higher risk than the general population. This is because these people have certain occupations or places of residence that may result in greater exposure to radiation. For example, workers at nuclear power plants, radiologists living near radioactive sites, patients receiving medical radiotherapy, and others.

Category B exposed also includes persons

A limited part of the population or category B of exposed persons in radiation hygiene are people who received a radiation dose of more than 50 rem or received an estimated dose of more than 7 rem, but in any case were excluded from group I (normal or healthy) for further observation. The radiation level below which a person is classified as group I is determined by regulations. In the Russian Federation, this level is set equal to 0.05 BER (biological equivalent of x-rays).

The limited part of the population is the population incapable of working, people with permanent work restrictions, war and labor invalids, workers of certain professions (military personnel and some other persons). Control over their radiation exposure is carried out by conducting radiation monitoring, as well as by monitoring individual doses of external radiation among workers in contact with sources of ionizing radiation (category A personnel).

A limited part of the population (exposed category B) is a part of the population that has been exposed to ionizing radiation, but does not have documented evidence of radiation conditions or an increased radiation dose. Although Category B is among the least studied categories of exposed individuals, scientists recognize that it may include people who were exposed to radiation unknown to be recorded or assessed in official documents.

This phenomenon can have serious consequences for people's health and well-being. They may have an increased risk of developing cancer, genetic mutations, and other radiation-related diseases. In addition, they may also experience psychological stress and psychological distress associated with feelings of uncertainty and uncertainty. For a more in-depth study of category B exposed people, the following studies can be used:

In radiation hygiene for such a concept is the concept of radiation exposure. People whose jobs involve hazardous working conditions, such as those who work in the nuclear industry, may encounter radiation problems that can affect
