Introduction

Interpretation of the National Standard of the People's Republic of China GB/T 17568—2019

1. Analysis of Standard Background and Technology Evolution

GB/T 17568—2019 replaces GB 17568—2008. The main revisions include:

Deleted "JJG591 Verification Procedure for Radiation Sources (for Radiation Processing)"
Added "GBZ128-2016 Occupational External Exposure Personal Monitoring Specification"
Redefined "Operational Qualification" and refined the safety interlock requirements

2. Comparative Analysis of Standard Framework

Standard Version	Major Changes	Scope of Application
GB/T 17568—2008	For the first time, it established the design, construction and use specifications of irradiation devices	Applicable to the construction and operation of γ radiation devices
GB/T 17568—2019	Added new operation appraisal requirements, refined the safety interlock system, and deleted some outdated clauses	Covering the full life cycle management of irradiation devices

3. Interpretation of core technical requirements

3.1 Radiation safety principles

The standard emphasizes the concept of Defense in Depth and ensures that the risk of accidents is minimized through multi-layer protection measures.

Redundancy: Use multiple independent systems to ensure reliability
Diversity: Different operating principles and physical variables reduce common cause failures
Independence: Safety facilities are isolated from each other to avoid chain reactions

3.2 Safety interlock system requirements

The standard puts forward strict requirements for the safety interlock system to ensure the safety of personnel and equipment. For example:

Source lifting interlock:The key is bound to the radiation detector, and the source cannot be raised unless the door is closed
Emergency source lowering:Automatically activated by multiple trigger conditions (such as low water level, smoke alarm)

4. Implementation suggestions

4.1 Installation and commissioning phase

It is recommended that enterprises strictly follow the standard requirements for equipment selection and system integration, and conduct comprehensive functional tests before commissioning. For example, the calibration of the dose measurement system must be traceable to the national benchmark.

4.2 Operation management

Establish a complete operation record system and regularly check the status of key facilities. Especially the source lifting system and the water treatment system, because of their high failure rate and safety impact.
