A questionair survery of the quality control and the radiation control was performed on the laboratories of 34 university hospitals, 29 community hospitals, 4 reserch institutes and 9 commercial radioassay laboratories as well. 1) Management of the usage of radioisotopes In 79% of the laboratories, the usage of radioisotope including the purchasing and discarding, was under the control of centralized organization, such as the central radioisotope division. The radioassays were performed by full time physicians in 18.9% and by technologists in 72.4% of the surveyed laboratories. 2) Management of instruments 90.8% of the laboratories has a regular program for background counting, examination for contamination and energy spectrum adjustment. The measurement of radioactivity and calculation of the data were carried out on an automated system in a majority of the laboratories : the percentage of the use of these automated systems were 92.1% for measurement, and 76.3% for calculation respectively. The automated system, however, which covers entire procedue : pipeting of samples and reagents, and B/F separation was used in only 7.9-18.4%. 3) Quality control 89.5% of the laboratory had a specific quality control program for radioassay. Main causes of errors they had encountered were : problems in commercial kits, handling of samples, instrument performance, technical and clerical errors in that order. To prevent these errors, it was thought important to establish the detailed protocols for the radioassay performance.
