영문 초록

Purpose: In general, We discharged radioactive wastewater and sewages less than 8.1×10-13 Ci/ml in a exclusive water-purifier tank. Our hospital operating three exclusive water-purifier tank for radioactive wastewater and sewages of 60 tons capacity respectively. In order to meet the criteria it need a enough decay more than 125 days per each exclusive tank. However, recently we fell into the serious situation that decay period was decreased remarkably, owing to the wastewater amount increased rapidly by enlarge the therapy ward. For that reason, in this article, I’d like to say the way that reducing of radioactive wastewater and sewages rationally. Materials and Methods: From January, 2006 to October, four hundred and two cases were analyzed. They were all hospitalized during 3 days and 2 nights. We calculated the average amount of water used (include toilet water used, shower water used, washstand water used, …), each exclusive water-purifier tank’s decay period, as well as try to search the increased factors about water-purifier tank inflow flux by re-analysis of the procedure of radioisotope therapy step by step. Results: We could increase each exclusive water-purifier tank’s decay period from 84 days to 130 days through the improvement about following cause: ① Improvement of conventional toilet stool for excessive water waste → Replacement of water saving style toilet stool ② Prevention of unnecessary shower and wash ③ Stop the diuretics taking during hospitalization ④ Analysis of relationship between water intakes and residual dose of body ⑤ Education about outside toilet utilization before the administration ⑥ Changed each water-purifier tank’s maximum level from85% to 90% Conclusion: The originality of our efforts are not only software but hardware performance improvements. Incidentally the side of software’s are change of therapy procedures and protocols, the side of hardware’s are replacement of water saving style toilet stool and change of each water-purifier tank’s maximum level. Thus even if a long lapse of time, problem such as return to the former conditions may not happen. Besides, We expect that our trials become a new reasonable model in similar situation.
