ABSTRACT:
A process for cleaning containers (pigs) in which radioactive drugs are shipped to health care providers, after than are returned to a pharmacy and may contain residual radioactive material, blood, microorganisms and other contaminants. Those pigs that are contaminated with radioactive material are removed from the cleaning process until they have decayed to the background radiation level. The upper and lower portions of each blood contaminated pig is disinfected. Each pig is washed at a temperature of at least 180° Fahrenheit for a least one minute to kill bacteria and viruses. The combination of a disinfectant and high washing temperature water provides an optimum level of sterilization.
