化学试剂储存有限数量包装安全监管豁免研究

化学试剂是科学研究的重要基础耗材,对多个学科的整体发展起关联推动作用。当前对于化学试剂的监管考虑其性质多,但综合考虑性质、数量、场景、措施的少,有必要根据《危险化学品重大危险源辨识》中的辨识指标确定不同性质和数量危险化学品的相对危险性。借鉴《危险货物道路运输通则》,探讨制定化学试剂储存有限数量包装的基本条件,制定化学试剂储存有限数量包装,进行监管豁免。通过对危险化学品的临界量、危险货物有限数量包装、危险货物有限数量包装的辨识指标的情况分析,为化学试剂科学监管提出了制定化学试剂有限数量包装、确定了安全监管豁免依据的标准。

Radiation Dose Monitoring and Analysis for the Construction of the Upgraded Beijing Electron-Positron Collider(BEPCⅡ) During Its Storage Ring Operation

In this paper,the average dose level is introduced in an environment and area when BEPCⅡis debugged. The typical dose graphs are offered when the electronic storage ring is debugged and works in the synchrotron radiation mode.At the same time,some suggestions about radiation protection are presented.All the data indicate that the main and local part shielding satisfy the need and attain the design target.
