（Ⅵ） Radioactive Safety
Radioactive Safety
1. The use of radioisotope and radiation- generation devices has to be approved by government environmental agency applied through university. Acquire Ra- diation Safety Permit. Affected areas should be identified with radioactive si- gns and placards. Records of radioact- ive sources should be kept by specific personnel. Check on a regular basis to ensure items match the account book.
2. Concerned personnel should receive training provided by environmental agency and acquire a Radiation Safety and Prot- ection Training Certificate. Upon certific- ate expiration, retraining is necessary.

3.Personnel involved in experiments with radiation should take the necessary prot- ective measures, operate according to gu- idelines, avoid air contamination, surface contamination and external radiation acc- idents. Wear dosimeters correctly.Partic- ipate in monitoring.
Radioactive Safety
4. Concerned personnel have to attend the physi- cal check-ups arranged by university.
Radioactive Safety
5. Students should attend lectures on radiation pr- otection and safety provided by advisors.Advi- sors are responsible for monitoring of st-uden- ts' behavior.
Radioactive Safety
6. The purchase of radioactive substances has to be approved by the laboratory and equipment management department as well as the district, civic and provincial environmental agency. For importing radioactive substance, it also has to be approved by the state environmental agency.
Radioactive Safety
7.If radioactive source spills or the package is broken, close all doors and wi- ndows as well as shut down the ventilation system. Report to the supervis- ors and the related departments immediately. Launch the emergency resp- onse and notify the neighboring staff to evacuate. Strictly control the affect- ed area. Forbid irrelevant personnel to enter. Reduce and control the level of effect.
Radioactive Safety
8. Radioactive Waste Disposal
8.1Sign disposal agreement with qualified companies to dispose the sealed isotopes with long half-life. Send the agreement to the laboratory and eq- uipment management department as back-up document.
8.2Isotope with short half-life should be separated and then collected accord- ing to the half-life and the date of production. Store them for 10 half-lives in specific radioactive waste containers. Once the residue radiation reac- hes the background level, dispose the isotope according to guidelines for average laboratory waste.

8. Radioactive Waste Disposal
8.3After finishing all the procedures applying to discard radiation-emitting de- vices like X-ray diffractometer, the crush of pressure vessel should be supervised by the staff from environmental agency and the university laboratory and equipment man- agement department.
8.4Radioactive chemical waste should be disposed by the qualified companies.
8.5Radioactive waste that has decayed to background level of radiation should be disposed according to guidelines for average laboratory waste.
