Decommissioning Procedure for Radioactive Source
Cobalt-60。

Cobalt-60 is a radioactive isotope of cobalt used in various industrial and medical applications. Due to its radioactive nature, the decommissioning of Cobalt-60 sources requires a comprehensive and systematic approach to ensure the safety of personnel and the environment.
1. Preparation.
Conduct a thorough inventory of all Cobalt-60 sources, including their location, activity, and shielding.
Establish a decommissioning plan outlining the methodology, safety protocols, and disposal arrangements.
Obtain necessary permits and regulatory approvals for decommissioning.
2. Decontamination.
Decontaminate the source and its surroundings using appropriate methods (e.g., chemical cleaning, scraping, or grinding).
Collect and dispose of contaminated materials as radioactive waste.
3. Source Removal.
Remove the Cobalt-60 source from its storage or usage location using specialized equipment and shielding.
Transport the source to a designated interim storage facility or disposal site.
4. Temporary Storage.
Store the Cobalt-60 source in a secure and shielded facility until it can be permanently disposed of.
Monitor the source regularly for any potential
radiation leakage or deterioration.
5. Permanent Disposal.
Explore available disposal options for Cobalt-60 sources, such as:
Near-surface disposal in a licensed radioactive waste repository.
Geological disposal in a deep geological formation.
Choose a disposal method that meets regulatory requirements and minimizes environmental impact.
6. Site Restoration.
Restore the decommissioned site to its original or
designated condition.
Conduct radiological surveys to ensure that no
residual radioactivity exceeds permissible limits.
Issue a decommissioning report summarizing the process and documenting the safety of the site.

钴60放射源报废流程。

钴60是一种放射性钴同位素，广泛应用于工业和医疗领域。

由于其放射性，钴60源的报废需要采用全面且系统的办法，以确保人员和环境的安全。

1. 准备。

全面清点所有钴60源，包括其位置、强度和屏蔽。

制定报废计划，概述方法、安全协议和处理安排。

取得必要的报废许可证和监管部门批准。

2. 去污。

使用适当的方法（如化学清洗、刮削或研磨）对源及其周围环境进行去污。

收集并处理受污染的材料作为放射性废物。

3. 移出源。

使用专用设备和屏蔽，将钴60源从其储存或使用位置移出。

将源运送到指定的临时储存设施或处理地点。

4. 临时储存。

将钴60源储存在安全且有屏蔽的设施中，直至可永久处理。

定期监测源的潜在辐射泄漏或劣化情况。

5. 永久处理。

探索钴60源可用的处理选择，例如：
在许可放射性废物填埋场近地表处理。

在深层地质构造中地质处理。

选择符合法规要求且最大程度减少环境影响的处理方法。

6. 场址修复。

将报废场址恢复到其原始或指定状态。

进行放射学调查，以确保没有任何残留放射性超过允许的限度。

发布报废报告，总结流程并记录场址的安全性。
