2. b. Food and drink are never stored in areas where radioactive materials are used or stored.

3. c. Always use laboratory coats, gloves, or other protective garments while handling radioactive materials.

4. d. Wear the appropriate monitoring device at all times while in areas where radioactive materials are used or stored.

5. e. Never pipette radioactive material by mouth.

6. f. All personnel should wash their hands after working with radioactive materials.

7. g. Monitor hands, feet and clothing before leaving the area and after each procedure.

8. h. Work should be performed on absorbent pads to catch spills and prevent splattering of liquids.

10. j. Do not dispose off non-radioactive waste in designated radioactive waste containers.

11. k. Work surfaces and trays should be smooth and non-porous.

12. l. Work with radioactive gases or other volatile materials (e.g., concentrated iodine solutions) should be performed in a ventilated fume hood. Never open sealed vials or bottles of radioactive materials in open areas if those contain volatile materials such as radioiodine.

13. m. Laboratory should be kept free of dust and dirt; floors should be washed twice.

14. n. Work areas should be kept tidy. Radioactive trash, contaminated pads etc., should be disposed off promptly.
