General Precautions
Preparation
Designate and label areas for working with radioactive material
Label all containers with a radioactive material label and specify the isotope
No eating, drinking or smoking in the laboratory
No mouth pipetting of radioactive material
Conducting the Research
Use spill trays and absorbent covering
Use fume hoods for handling potentially volatile material
Use glove box for handling large quantities of volatile material
Wear laboratory coat, disposable gloves, and laboratory safety glasses
Use gloves appropriate for the chemicals to be handled
Post Research
Monitor and decontaminate surfaces as described in Chapter 7 of the Radiation Safety Manual
Dispose of radioactive waste in waste containers in accordance with Appendix G of the Radiation Safety Manual. Insure the container is labeled with a "Radioactive Material" label and specify the radioisotope in the container.
