"Technical Specifications for Radiation Environmental Monitoring" National Ecological Environment Standards Released

[ Policies and Regulations of Chemical Machinery Equipment Network ] To implement the Environmental Protection Law of the People’s Republic of China, the Law of the People’s Republic of China on the Prevention and Control of Radioactive Pollution, and the Nuclear Safety Law of the People’s Republic of China, to protect the ecological environment, protect human health, and regulate the quality of radiation environment monitoring, For supervisory monitoring and emergency monitoring, *The "Technical Specifications for Radiation Environmental Monitoring" is now approved as the national ecological environment standard and will be promulgated.

This standard will be implemented on May 1, 2021.
From the date of implementation of the standard, the "Technical Specifications for Radiation Environmental Monitoring" (HJ/T 61-2001) shall be repealed, and the "Regulations on Environmental Nuclear Radiation Monitoring" (GB 12379-1990) The implementation of the corresponding national radioactive pollution prevention and control standards shall be suspended.

 

my country's nuclear and radiation environmental protection undertakings are developing rapidly, and higher requirements are put forward for radiation environmental monitoring.
The requirements for different nuclear and radiation facilities, equipment, site monitoring programs, quality assurance, and data processing are getting more detailed and higher.
The public’s demand for environmental information is also increasing.
Nuclear and radiation environmental monitoring data are both difficult and sensitive to the public, and the requirements for government information disclosure are also increasing.
Revising and perfecting this standard can better serve the nuclear and radiation monitoring data.
Radiation safety supervision provides technical support and better serves the public.

my country's current "Technical Specifications for Radiation Environmental Monitoring" was promulgated in 2001 and has not been revised for more than ten years.
The past ten years has also been a period of rapid development of radiation environment monitoring technology and capacity building.
During this period, many radiation environment monitoring methods have been revised and improved, and the infrastructure and technical capabilities of radiation monitoring stations in various regions have been greatly improved.
Therefore, the relevant requirements in the current version of the technical specifications have lag far behind the current monitoring technology and requirements, and are seriously out of touch with reality.
It is urgent to revise and update the original technical specifications.  

　　In order to implement the Environmental Protection Law of the People’s Republic of China, the Law of the People’s Republic of China on the Prevention and Control of Radioactive Pollution, and the Nuclear Safety Law of the People’s Republic of China, and to guide and standardize the monitoring of radiation environmental quality and radiation source environmental monitoring at all levels, this standard has been formulated.
(specifications).

 

　　This standard specifies the main technical requirements for radiation (*in ionizing radiation) environmental quality monitoring and radiation source environmental monitoring, including on-site measurement, sample collection and management, monitoring methods, data processing, quality assurance, and preparation of radiation environmental quality reports, etc.
.

 

　　This standard* was issued in 2001.
The original standard drafting unit was the National* Nuclear Safety and Radiation Environmental Management Department.
This is the *th revision.  

　　The main contents of the revision are as follows: according to domestic and foreign* radiation protection, environmental monitoring standards and guidelines, various nuclear and radiation facility monitoring programs have been revised; based on the summary of monitoring practices in the past two decades, some provisions of the original standards have been summarized Adjustments were made, and individual errors and inappropriate points were modified; marine and NORM radiation environmental monitoring contents were added; sample collection and management, determination of monitoring methods were refined, and practical indicators such as sampling volume and lower detection limit were added.
Make this standard more practical; revise quality assurance and data processing in accordance with domestic and foreign* requirements; revise part of the content of the original standard method.

 

　　The documents cited in this standard include: GB 18871 Ionizing Radiation Protection and Radiation Source Safety Basic Standard; HJ 168 Environmental Monitoring and Analysis Method Standard Preparation and Revision Technical Guidelines; GB 3097 Sea Water Quality Standard; HJ 969 Nuclear Power Plant Pre-operational Radiation Environment Background Investigation Technical Specification; HJ 1009 Technical Specification for Operation of Automatic Radiation Ambient Air Monitoring Station; HJ 663 Technical Specification for Environmental Air Quality Assessment; HJ/T 164 Technical Specification for Groundwater Environmental Monitoring; HY/T 235 Technical Specification for Radionuclide Monitoring in Marine Environment; GB 8999 Ionization General Regulations for Radiation Monitoring Quality Assurance; HJ 630 Technical Guidelines for Environmental Monitoring Quality Management; GB/T 4091 Conventional Control Charts; GB/T 8170 Numerical Rounding Rules and Limit Value Representation and Judgment; IAEA/AQ/48 Determination and Interpretation of Characteristic Limits for Radioactivity Measurements GB/T 4883 Data Statistical Processing and Interpretation Normal Sample Outlier Judgment and Processing; GB/T 4889 Data Statistical Processing and Interpretation Normal Distribution Mean and Variance Estimation and Testing; HJ 641 Environment Technical specifications for quality report compilation; CNAS-CL01-G003 measurement uncertainty requirements; GB/T 27418 measurement uncertainty evaluation and expression.

 

　　Radiation environmental monitoring (radiation environmental monitoring) is also called environmental radiation monitoring, which refers to the measurement of the radiation level in the environment (external exposure dose rate) and the radionuclide content in the environmental medium in order to understand the level of radioactivity in the environment, and the measurement results Explain the activity.
The narrow sense of radiation environmental monitoring refers specifically to ionizing radiation environmental monitoring.
At this time, the radiation environmental monitoring is also called environmental radioactivity monitoring.
The broad sense of radiation environmental monitoring also includes electromagnetic radiation environmental monitoring.
In this standard, it is more than the narrow sense of radiation environmental monitoring.  

　　Radiation environmental quality refers to the level of radiation in the environment.
In this standard, it is specific to a limited environment, and for different environmental conditions, some comparable key radiation parameters are selected as indicators to measure the radiation environmental quality, so as to realize the description, comparison and evaluation of the radiation environmental quality.

 

　　This standard applies to radiation environmental quality monitoring and radiation source environmental monitoring organized by the ecological environment competent department.
The radiation environment monitoring carried out by other departments can be used as reference.
