Radioactive iodine is used in several procedures on campus. The radiation safety staff is concerned mainly with iodination procedures. These procedures can be very cost effective for researchers, but several additional safety considerations must be met. Due to the volatility of the compounds used, air monitoring is involved as well as thyroid bioassays post-experiment to assure that no iodine uptake occurred. Before doing any iodinations, please contact Mike Nicholson for an air filter as well as an appointment for a bioassay. These safety considerations are extremely important in preventing unnecessary exposure.
