When you receive the package in the lab, it must be opened in a designated area such as a fume hood or lab bench. If contamination is greater than 50,000 cpm, notify the vendor for possible replacement. Provide shielding if necessary. Store the stock vial in a designated, posted area. Return form to RPS when the radioisotope is expended.
Most radioactive compounds have a limited shelf life due to radiolytic decomposition.
If the shelf life has been surpassed, the chemical integrity of the compound cannot be assured. Contact you vendor for further information.
