  The integrated disposal system was developed to make sure the disposal of wastes concerning positron emission tomography to comply with the regulations. The system consisted of a management system concerned with the data of wastes and a measurement system concerned with the residual radioactivity of wastes. The information of wastes was stored into the tags. The tags were pasted on the top surface of the container holding wastes. The tag's data was read by the reader. The reader was placed on the base and side surfaces in order to evaluate the dependency of the kind and volume of wastes respectively. The rate at which the reader succeeded in reading was researched. The successful rates in reading depended on the position of the tags and readers. The detection limit of the system was evaluated with the source 99mTc to be 218 Bq. The specific period for decay from 218 Bq to one atom of 18F was estimated to be 39 hours.<br>
