Primary locations for nuclear medicine activities are:

  • Nuclear Pharmacy (in Radiology)
  • Scintillation Camera Room (Radiology)
  • Equine Nuclear Medicine Stalls
  • Radiology hallway (from Equine stalls to camera room)
  • Small Animal Medicine Ward
  • Necropsy cooler


  • Do check status of survey meter before every use as noted earlier.
  • Do wear personal dosimeter badges when cleaning the nuclear medicine stall, working around sources of radioactive material, x-ray machines, nuclear medicine patients or their urine or feces.
  • Do read and follow the rights and responsibilities on the State Notice to Employees.
  • Do report areas that should be kept locked for security of radioactive materials, if they are not locked.
  • Do put all radioactive waste in a well marked, appropriate container. Waste can be liquid, sharps, or solid radioactive waste including used protective clothing.
  • Do notify your supervisor or the Radiation Safety Office (231-5364 or through the Virginia Tech Police at 911) immediately if there is a spill of radioactive material, or some other event or you are asked to get help.
  • Do notify the Radiation Safety Office anytime you have a question or want to declare your pregnancy.
  • Do ask to see your radiation dose report if you have a dosimeter badge and you are concerned about your dose history.
  • Do wear lab coats and gloves any time you may come in contact with radioactive materials or a radioactive patient. Carefully remove gloves and wash hands with soap and water when done.
  • Do wear booties or protective shoe covers if there is a chance that you will enter a nuclear medicine stall.
  • Do get training in the control of patients, visitors, contamination, waste, and become informed on how to notify the Radiation Safety Office and the Principal User before working with radioactive materials or animals.
  • Do insure that all nuclear medicine patients remain until 24 hours post injection.
  • Do notify the Radiation Safety Office if a radioactive nuclear medicine patient requires surgery. Establish contamination control by wearing protective clothing, consider all equipment and supplies contacting the patient contaminated and clean equipment and work areas and survey for contamination prior to reuse.
  • Do notify the Radiation Safety Office if a radioactive nuclear medicine patient dies. If a nuclear medicine patient dies or is euthanized before it reaches background radiation levels, the carcass must be stored in a probably marked area in the necropsy cooler until background radiation levels are reached.
  • Do use time, distance, and shielding consistent with good patient care. Limit time to only that needed to do the job (anything routine that can be done away from the patient and radiation fields should be). Syringe shield should be used whenever possible.
  • Do insure that stalls are not cleaned until 60 hours post injection, they are surveyed and are indistinguishable from background and radioactive material signs and cable ties have been removed fro the stall.
  • Do clean stalls, runs, and cages with copious amounts of water. Avoid splattering.
  • Do always use two persons to transport any patient and have a spill kit available. Use a cart or carrier with absorbent and muzzle when appropriate.
  • Do if an equine nuclear medicine patient urinates in a hallway, avoid the splatter, warn others, cordon off the area and contract the RSO for assistance.


  • Don't allow owners or visitors to touch or enter stalls or runs. Visits should be discouraged and all visitors should be escorted by a student or clinician.
  • Don't clean stalls until released by Principal Users. Seek them out during any emergency. They include Drs Daniel and Larson, Valerie Vaught, Jennifer Hurt among others.
  • Don't prepare or administer radiopharmaceuticals unless you are a Principal User.
  • Don't enter stalls or runs with "Caution Radioactive Material" signs.
  • Don't enter or clean the nuclear medicine stall from the "A Barn" side. Always clean it from the radiology hallway door.
  • Don't eat, drink, or store foods in areas where radioactive material is used or stored. Look out for "Caution Radioactive Material" signs.
  • Don't have unnecessary objects in radioactive material areas where they may become contaminated.
  • Don't work around or use radioactive material unless you have been trained by lecture or this material, pass the nuclear medicine test, and have a radiation dosimeter badge.
  • Don't flush small animal urine or feces until after 24 hours.
  • Don't flush small animal runs unless you are a Principal User.
