Emergency Procedures for Spills of Radioactive Materials

Call the 辐射安全主任 if any of the following is true:

• 皮肤或衣服上的污染.
• Activity of the spill is greater than 10μCi.
• The spill is outside of the immediate work area.
• The spill covers a large area or volume.

1. 使用 游泳!
   • S – Stop the spill and stop what you’re doing (stop your 研究). Cover the spill with absorbent paper (dampened if spilled material is solid).
   • W -警告该地区的其他人. They may not be contaminated and need to know.
   • I  – Isolate the area so others don’t get contaminated. 如果可能的话，使用胶带或缎带.
   • M – Monitor for skin contamination and clothing contamination. 经常更换手套.
   • S – Survey and cleanup the contaminated area. Do not forget your dosimeter or the proper protection equipment: gloves, 实验室外套, 保护眼睛, and booties (shoe coverings) before attempting to clean the spill. Mark the perimeter of the spill and isolated spots. Thoroughly clean by wiping the contamination with absorbent paper (preferably with Radiacwash or Count-off) working from the perimeter towards the center of the spill.
2. 还记得, used radioactive absorbent paper must be disposed of in the respective radioisotopes’ waste container (i.e. 32P废物装入32P容器等). Carefully fold the absorbent paper with the clean side out and place in a plastic bag for transfer to the proper waste container. Put contaminated gloves and any other contaminated disposable material in the bag.
3. Once finished with the decontamination, survey the area to make sure that it is reading background levels. Perform an extensive personnel survey. Take your time in surveying the hands, shoes, 实验室外套, pants, and face.
4. Do not allow personnel to return to work until area is cleared by the RSO.
