Various nuclear radiation dose detection instruments are generally used for measurement, so that nuclear accidents of nuclear power stations and other nuclear industrial production facilities can be timely monitored and evaluated, and influences on surrounding residents and living environments are reduced.
The monitoring method is divided into environmental monitoring and personnel monitoring according to monitoring objects. The environmental monitoring refers to nuclear radiation monitoring of infected areas, equipment, water sources, materials and the like which can generate radiation hazards, and comprises early nuclear radiation environmental monitoring and residual nuclear radiation environmental monitoring. The method mainly monitors the doses of gamma radiation and neutron radiation in early nuclear radiation, determines the distribution, decay rule and contamination level of the surface radioactive contamination in a contaminated area, and further measures and evaluates the radioactive contamination degree of air, water sources, food, weaponry, engineering facilities and the like.

Including the measurement of radioactive contaminants in ground, air, water, soil, various objects, effluents and biological samples. Generally, the classification is three types: (1) background monitoring. The natural radiation background level is obtained, so that basis is provided for making a conventional monitoring plan and evaluating a monitoring result. (2) And (5) performing routine monitoring. Radiation monitoring is performed to understand the environmental conditions of a nuclear facility during normal operation to determine whether or not the environment is contaminated or the extent of contamination. When confirming the environmental pollution, the collective dose and the equivalent of the collective dose of nearby residents are measured to evaluate the degree of harm. (3) And (5) monitoring an emergency accident.
