Following the crisis at the Fukushima Daiichi Nuclear Power Plant caused by the 2011 Tohoku earthquake and tsunami, radioactive substances ((131) I, (134) Cs, (137) Cs) were detected in tap water throughout eastern Japan. There is now concern that internal exposure to radioactive substances in the dialysate could pose a danger to hemodialysis patients. Radioactive substances were measured in three hemodialysis facilities before and after purification of tap water for use in hemodialysis. Radioactive iodine was detected at levels between 13 and 15 Bq/kg in tap water from the three facilities, but was not detected by reverse osmosis membrane at any of the facilities. We confirmed that the amount of radioactive substances in dialysate fell below the limit of detection (7-8 Bq/kg) by reverse osmosis membrane. It is now necessary to clarify the maximum safe level of radiation in dialysate for chronic hemodialysis patients.
2011年东北地震及海啸引发福岛第一核电站危机后，日本东部各地的自来水中检测到放射性物质（碘-131、铯-134、铯-137）。目前担心透析液中的放射性物质内照射可能对血液透析患者构成危险。在三个血液透析设施中，对用于血液透析的自来水净化前后的放射性物质进行了测量。在这三个设施的自来水中检测到放射性碘的含量在13至15贝克勒尔/千克之间，但在任何设施中通过反渗透膜均未检测到。我们证实，通过反渗透膜，透析液中的放射性物质含量降至检测限（7 - 8贝克勒尔/千克）以下。现在有必要明确慢性血液透析患者透析液中辐射的最大安全水平。
